This is a guest post from Aaron Henckler.
Waterfall charts are great, especially for visually showing the contribution of parts to a whole. While there are several tutorials on how to make a waterfall chart online the end products of these tutorials rate low on the visually appealing scale.
The principle problem with these charts is the separation between the elements of the waterfall. They are always either pushed together (Example A) or left apart, without element connectors (Example B):
Example A
Example B
Many users of waterfall charts employ the separated (default) version (example B) opting to add in element connectors manually via Insert>Shapes>Line on the Excel tool bar. The frustration with this approach is that all too often the values of the chart elements will need to be updated or changed forcing user to manually readjust each of their connector lines in turn.
With some simple charting trickery in Excel 2007 one can easily make a waterfall chart with connectors that will update automatically as element values are changed.
A Better Waterfall Chart
Steps to Building a Better Waterfall Chart
List of data series (columns) needed for your chart:
- Horizontal Axis Labels: in the example above North, East, South and West.
- Base Values: What your element values will “sit on.” Essentially this is the white space beneath each charted element shown above.
- Element Values: the meat and potatoes of your chart – the value of your elements as you want them to appear (above these are 40, 30, 20, 10 and 100).
- Label Spaces: This is optional but it allows you to place the value of you data elements on top of their respective bars (this avoids the use of the annoying Label Position options available after one has used Add Data Labels).
- Label Connectors: This is the key item needed to create the chart as shown above. You will need one column (series) for each of the data elements (excluding one for the total). For the chart above, four label connector series are needed.
Step 1: Enter all of the required series in a worksheet:
- Horizontal Axis Labels – self explanatory
- Base Values – A running total of the subsequent Element Values (Column C). Whereas nothing proceeds North in the example above leave its base value blank. Do the same for Total.
- Element Values – These are whatever numbers you want to highlight in your chart. These are represented by the blue column segments in the above chart.
- Label Spaces – Again this is optional. These will eventually hold text labels for the Element Values (Column C). The numbers here should all be the same and be some number about 1/4 to 1/3 the value of your lowest Element Value.
- (to H. ) Connectors – Connectors 1 to 4 correspond to Axis Labels North to West in the example above. In the respective Connector column make the cell at the row corresponding to the related Axis Label equal to the sum of Column B + Column C (Base Value + Element Values). Enter the same value for the cell beneath.
Step 2: Chart data and adjust
1. Select your data, here A2:H6, and go to Insert>Charts>Column>2-D Column>Stacked Column>OK (to exit). Your chart should look like this:
2. Switch column and row data by right-clicking within the chart and going to Select Data…>Switch Row/Column>OK (to exit). Chart should now look something like this:
3. The top colored column element in each column (purple, aqua, orange and baby blue, respectively) is what will become that Element Value’s connector. To convert to these columns to connectors, in turn, right-click on the series (the first one is the purple column element) and go Change Series Chart Type…>Line>Line>OK (to exit). Repeat this process for the other connector column elements (aqua, orange and baby blue). After this step your chart should look like this:
4. Follow this up by formatting each connector in turn. Right-click on the connector and go Format Data Series…. Consider making the Line Color>Solid Line>Color black, Line Style>Width .25 pt and Line Style>Dash Type>Square Dot. Play around with these options as you see fit to get the best look. Again, do this for each connector.
5. Remove grid lines (optional), delete the Legend (necessary). Your chart should now look like this:
6. Go into you Base Values series (blue column element in the chart above) and eliminate the color fill and borders: right-click on a blue column element and go Format Data Series….>Fill>No Fill and Border Color>No Line>Close (to exit).
7. Format your Element Values series (red above, using same process in Step 6 to change the fill color and add a border.
8. Right-click on your Label Spaces series and go Add Data Labels…. Don’t worry about the value on the labels for now, they’ll be changed in the next step. Follow this up by formatting the Label Spaces series just like how the Base Values series was formatted (in Step 6). Make it so there is no fill and there are no borders. This is what you should now have:
9. All that remains is to convert your labels to the values of the Element Values. To do this for each label: click on the specific label twice (so that only the box for that label appears, as below).
Click a third time on the edge of the box that appears and then type the equals sign “=”. Now go back to your data table and click on the cell of the Element Value that you want appear in the label. Then press enter. This links the value of the label to the Element Value (if your Element Value ever changes so too will the text in this label). Repeat this for the other data labels in turn. The result is your Better Waterfall Chart:

Final Thoughts
I hope you will agree that this waterfall chart is more visually appealing that the examples at the start of this tutorial. In addition to a more professional look this waterfall will fully update (step heights, labels, connector positions) automatically whenever you change your Element Values. While the process of implementing this form of waterfall chart may at first seem cumbersome it can be quickly implemented with some practice and is a great item to have in your charting toolkit. Enjoy.
Note from PHD:
- Thank you so much Aaron. You have taught us a very valuable tutorial. I really appreciate your effort in putting this together.
- If you need to make a lot of waterfall charts, I recommend trying Jon Peltier’s Waterfall Chart Utility.

I see most are saying that array formulas are bad. But I thought that when you use array formulas it grabs all the data at once and performs the calculations in one fell swoop. At least that is how the UDFs that I created work. When I did the time test it was much faster that way. Maybe I'll go back and check to make sure my work is right, but that's what I did.
When I work with array formulas I get a full column of data then work on that column and return a full column of data all at once. Which has shown to be much faster than the alternative.
Anyone have special insights on this?
wow..! thats a pretty impressive list, some real gems in there. I read somewhere the other day that spreadsheet development should be 80% planning and 20% implementation - taking the time to think about layout, how you're going to calculate things and how to structure the data often results in a lot less headaches, and more time for deeper analysis...
Hi Chandoo...
Mixed feeling about this article, while I completely agree with you when you share everyone's points under their name giving credit to contributors, but at the same time I see alot of repeated tips and few those may not be applicable under all cases. (I may have sounded harsh). Some kind of sorting of tips were required than mere 3 categorization. (Tough ask, I know). Some really worthy and awesome tips get lost in occean.
I would have been happy to read only non repititive tips and more like standard chandoo articles.
Well, I have also got two tips (may get lost in the list above), which is not presented above:
1. When using too many pivots - Disable data drilling option. This reduces file size, cache memory and speeds up file.
2. If your macro has used too many files for gathering input, close the file and open. This is also release or kill unwanted space in memory and speeds up. Again this can be achieved by macro to close self file and reopen same file, using timer function.
Please do not count me negative.

Hey, one thing that really speeds up VBA processing of data is to extract ranges into arrays & then working on those arrays. Arrays are a lot faster than using cell offset or any other method for working with a database. After you are done you can also paste the value directly into the range with one single command. This will speed up the macros considerably.
Here is a msdn article with examples in it:
msdn.microsoft.com/en-us/library/aa139976(v=office.10).aspx
Hope this helps
oops, noticed a typo in the tip I posted:
Re directly assigning values in VBA rather than copying & pasting should have read:
Sheet2.Range( "B1:B200 ").Value= Sheet1.Range( "A1:A200 ").Value
not
Sheet2.Range( "B1:B200 ").Value= Sheet1.Range( "A1:A100 ").Value
Corrected with double quotes:
Sheet2.Range("B1:B200").Value= Sheet1.Range("A1:A200").Value

OK, I tested it. My UDFs were faster as array functions (like a couple thousand times). But Excel's built in functions are faster when not doing arrays. Not sure this is the case for all situations.
I can't help but to speak up.
Deleting a PivotTable will not speed up your workbook. It will only reduce the file size. There is zero memory processing for a pivot table if it just sits there.
Instead of destroying the pivot table, why not remove the redundant raw data. That would equally reduce the file size of the workbook, while keeping the pivot table functionality.

Thanks a lot guys for your valuable tips !!
It really worked for me
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
...
...
...
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
I would add:
Application.StatusBar = "Wait a second..."
............
Application.StatusBar = False
Optimizing Speed using Pivot Tables:
If you find that Pivot Tables are becoming sluggish becomes of the sheer volume of tables there is a way to increase performance. By default (xls 2010) pivot tables are designed to autofit the data within the columns as well as preserving formatting. I discovered that unchecking these two options alone will exponentially increase performance.
Here's how to do it:
Right click on your pivot table(s) --->choose 'Pivot Table Options' -->Layout & Format' Tab --->uncheck two boxes at the bottom. Done!
here is my list:
1. Avoid Variants when possible
2. Use long instead of integer
3. Use double instead of single
4. Use booleans as much as possible
5. pull data into arrays, manipulate, then dump back to workbook
6. use .value2 instead of .value if you are looking at strings or numeric values
7. set object variables
dim Wks as Excel.Worksheet
set wks = thisworkbook.Sheets("Sheet1")
8. use with statements...
with wks.cells(x,y)
.value2 = "abcd"
.interior.colorindex=4
with .font
.bold=true
.size =20
.underline=xlunderlinestylesingle
end with
9. use string version of functions (Left$() instead of Left())
10. Test for empty string variables with len() or lenb()...if lenb(String1)=0 then
11. Use the Mid$() function if it is possible instead of split()
12. use the join$() function instead of concatenating strings
13. AscW() to evaluate first characters
14. combine if statements and booleans together
boolean = (lenb(String1) = 0)
16. InStr(), InStrB(), InStrRev() are very fast, InStr() can be used to quickly return a substring occurrence of a string
17. DICTIONARIES!!!!!!!!!!!
18. FileSystemObject
19. My machine runs slightly faster when i fill in all the inputs of a function (instead of InStrB(String1, "abcd"), i use (InStrB(1,String1,"abcd",vbBinaryCompare)
20. Short Circuit If statements: If x = 2 then if y >3 then if z = 5 then b=true or
if x=2 then
if y >3 then
if z=5 then
b=true
c=true
end if
end if
end if
21. use ElseIf
22. my testing indicates ElseIf is slightly faster than a Case Select
23. set strings to empty by: = vbnullstring
24. with application
.screenupdating = false
.displayalerts = false
.enableevents = false
end with
25. UserForms can be very beneficial
26. User-Defined Types are a very neat way to encapsulate data
27. User-Defined Functions are handy, but can increase run-time if called thousands of times
28. if using ElseIfs, nested And Ifs or Select Case statements, put the argument that will occur most frequently at the beginning
29. Looping is not the worst thing...just got to figure out how to do it the most efficiently
30. Use dynamic arrays instead of static arrays
31. if you can figure out Win32 APIs, then they are usually much faster than VBA functions
I worked on a massive spreadsheet and it had become very slow over time as I developed it. I tried stripping down more and more formulas by replacing with pasted values, removed all conditional formatting etc. In the end what finally did the trick was when I removed the last single SUMPRODUCT fomula. It changed the updating time after one change from 7-8 seconds to instantaneously. The SUMPRODUCT I had used the full columns, and if I put it to only look at rows 1-500 it was fine.

TIPS FOR SPEEDING UP EXCEL
(1) Instead of writing a lot of formulas to organise data, you can VLOOKUP() the data in a Pivot table, thereby combining the advantages of Pivot table and VOOKUP().
(2) If you have a range named ‘TotalTaxForTheCurrentFinancialYear’, then it is not compulsory to use this name when making the worksheet. Naming the range as ‘Tax’ or simply ‘T’ will be sufficient. The formula =SUM(T) will be shorter and easier to use.
After completing typing all the formulas, simply edit the name of the range from ‘T’ to ‘TotalTaxForTheCurrentFinancialYear’, in the name box. The formula =SUM(T) will automatically change to =SUM(TotalTaxForTheCurrentFinancialYear).

I don't write many macros and like most of you when doing a recalculation it sometimes takes forever.
I have found that when I looked at my spreadsheet, I could determine which order of calcuations (by column) would produce the least number of iterations. So I wrote a macro to do my calculations on my terms. I picked the order of the columns I wanted to calcuate and it sped up my recalc 5-10X.
I did this so long ago, I believe I used "expression .Calculate".
TIPS TO SPEED UP EXCEL by Vijaykumar Shetye, India
You can view all the formulas in the entire worksheet quickly by pressing [ctrl] and [~] keys simultaneously.
To view results, press the key combination again.

I've had to do a lot of mass calculations for reports etc. that involved repetitive identical, yet complex formulae, which took forever...
I hit on a great time-saver: sort the spreadsheet data; if, for example, the same result was due to a lookup of Hotel Name (A column), Date (B column), and Room Type (F column), the formula (Z column) would be: "=IF(A2&B2&F2=A1&B1&F1,Z1,VLOOKUP(A2&B2&F2,LookUps!A:G,7,FALSE))".
This meant that if the result is the same as the row above, just use the same answer, thus saving loads of time instead of VLOOKUPs. (This is a simplified example, the actual one had INDIRECT(ADDRESS...) in it, too!)
Check files for invalid range names, invalid links and names that aren't needed any longer.
Clearing out some 200 old references in a template made the file open go from 30 seconds to 2.
You can improve the speed by stopping calculation during changing cell value and after that you can enable it. please follow the link.

If you want to highlight the content or result within a cell with colour, use content colour not cell fill colour. This make a large data sheet fast as full colour takes up more resource.
There are already so many useful replies, so don't be mad at me if I repeat someone with the following hints.
While using pivot tables:
1. Link (raw) data from external files, rather then building pivots in the same workbook of the data. => Reduces file size.
2. don't flag "keep source data" in pivot settings. => reduces cache.
Downside is when you want to use slicers, you must allow refresh of the source data and thus people need access to that file.
One extra when using tables above ranges: replace the table header references by cell references in heavy duty formulas. I'm not sure but it seems to be faster and lighter (in #MBs).

In VBA, send out values to the worksheet all together as an array then excel will only re-calculate once rather than each time a cell that is output.
to the guy who said avoid looping in VBA - easier said than done, it's one of the most powerful uses for VBA out there. I'd therefore recomend the half way house and break the loop as soon as you've got what you want, don't let it run until the end. Use While etc.
What I would say on VBA in general is minimise sheet to code interations. Suck all your data into a VBA array THEN do the maths don't use cells themselves as stand alone visual variables.
And to the lady who said it's faster offline - that's because Microsoft are constantly contacting their own website be it security verification and/or update checks
Apply some logic to the order of criteria in sumifs / countifs formula
order the most exclusive criteria first. Once one criteria fails the others do not execute.
Bing AI, given the following query, confirms this: "excel countifs. if one criteria is likely to exclude most of the data range then should this criteria go first in the list to prevent frivilous executions".
