Once you start using Excel to develop systems, budget, forecast and large tables of data you may come across the dilemma of “How do I know this is right” or “How do I truth check this”.

This post, Huis second, will add a tool to your arsenal to help you out.

The technique below allows for the rapid visual evaluation of 12 or more days/months/years of data via a chart of 2 variables and the ratio between them, utilising 2 sliders to rapidly change input variables.

DATA

Typically all businesses deal in 3 types of numbers, ie: Dates or Times, Physicals and Dollars.

Dates may include Times, Days, Weeks, Months, Years or any periods in between

Physicals directly relate to the business you are in but may include inputs and or outputs: eg: metal, tyres and cars, sugar, flour and cakes or whatever your business makes, strangely Physicals may also include Dollars, if you’re in the financial services sector. People are a Physical.

And Dollars which could be revenue, costs, cashflows or profit types of numbers.

I have found one of the best methods of looking at large tables of data is to look at a key input or output physical and then interactively scroll through the cost or income and calculate a ratio between the two.

I am going to use as an example a budget which has 40 rows of data including Physicals and Costs. But you will see that the techniques here can easily be extended to hundreds of rows. You can download this file here: Bobs Homes

The technique below allows rapid visual evaluation of 12 or more months data a chart of 2 variables and the ratio between them.

Using 2 sliders the user can rapidly move between variables and evaluate the variance over a given time frame against another variable.

The technique involves the charting of 3 ranges which in turn will be controlled by 2 sliders.

The first Range and slider will allow the selection of a Physical.

The second Range and slider will allow the selection of the Cost/Income component.

The third range will be the ratio of these, but specifically cost or income per physical.

I have attached a workbook, Bobs Homes, which contains 2 models, an example model for you to practice the following techniques on and a completed model which you can examine and pull apart to see how it works.

Bobs Homes

Load the model and scroll around and see what data is available. You will notice a time scale across the top with Physicals and Dollars down the left side. The Physicals and Dollars are grouped into common areas like inputs, outputs and costs, income and profit.

You will also note that there are 10 blank rows at the top of the worksheet. I do this so that I can perform simple calculations, charts or other workings without upsetting the data and other calculations below and for macro’s which automatically find the bottom of the data I know there is nothing below my data to upset the calculations.

Let’s jump in

SETUP

We’re going to add the following components

Headings

A2: Physical

A3: Cost/Revenue

A4: Ratio

E1: =E12

and copy across to Q1

Data

C2: 1

C3: 1

D2: =CONCATENATE(OFFSET(B$13,$C$2,0),OFFSET(C$13,$C$2,0))

D3: =CONCATENATE(OFFSET(B$22,$C$3,0),OFFSET(C$22,$C$3,0))

D4: =CONCATENATE(D3,”/”,D2)

E2: =OFFSET(E$13,$C$2,0)

E3: =OFFSET(E$22,$C$3,0)/1000

Copy E2:E4 across to Q2:Q4

Chart

Select Area D1:Q4

Insert Chart, Line Chart with or without markers to your liking

Suggestion – Place the Chart between the Data and the new Headings and formulas you have just added

Adjust the Legend to be at the Bottom of the chart

Sliders

Insert 2 Sliders

Developer Tab, Insert Scroll Bar (Form Control)

If you don’t have the Developer Tab, Have a read of: http://chandoo.org/wp/2009/05/26/excel-2007-productivity-tips/

Position the scroll bars so they are vertically next to the Chart, Use Alt whilst dragging to snap to Cell corners or edges

Link the sliders to the lookup cells

Slider 1
Current value: 1
Minimum: 1
Maximum: 7 (This is the number of Rows of Physicals data)
Incremental Change: 1
Page Change: 0
Cell Link: $C$2

Slider 2
Current value: 1
Minimum: 1
Maximum: 19  (This is the number of Rows of Cost/Revenue data)
Incremental Change: 1
Page Change: 0 (set this to maybe 10 if you have more than 30/40 rows)
Cell Link: $C$3

FINAL MODEL

You can now select a Physical by dragging the Left Scroll bar

You can now select a Revenue/Cost by dragging the Right Scroll bar

The Ratio of Cost/Revenue to the Physical is calculated and the 3 are all charted

Examine the model and see what variances in inputs/outputs can be seen.

HOW DOES THIS WORK?

The Formula in E2:Q3, are extracting the physicals and Cost/revenue data from the main body of the report by simply using an Offset function from the top of the Physicals and Cost/Revenue area.

The Distance they offset is retrieved from the control Cells C2:C3

The labels for the Physicals and Costs/Revenues are also retrieved using 2 Offsets inside a Concatenate. This is done to allow Heading Rows and Sub Headings to be displayed and joined if available from 2 separate columns.

The Chart is a simple Line Chart which is charting the 3 Data Rows (E2:Q4) against the Time Period (E1:Q1) at the top of the work area.

You can customise the chart to your content.

The 2 sliders control the control Cells C2:C3, and allow for interactive selection of Physicals and costs.

In use often you will find that one of the Physicals, Costs/Revenue or Ratio is generally much smaller in scale than the other 2 measures. Generally it is a good idea to plot the odd scale against a secondary Y axis.

Select the series line, Right Click and select Format Data Series

24 Responses to “10 Supercool UI Improvements in Excel 2010”

  1. Hui... says:

    The best improvement by far is the Collapse Ribbon ^ button !

  2. Alex Kerin says:

    Kind of a shame that some of the best improvements are actually returns to old functionality. One thing I don't like is that to get to recent files I need to do an extra click after File - apart from Save As, that's why I'm usually in the File menu. I like the sparkline options, though they are still as not fully featured as some of the free and pay options out there.

  3. Arti says:

    The collapse button for the ribbon menu is good news. Can you make the ribbon menus stick too?

  4. Jon Peltier says:

    Nine improvements, not ten. You can also select multiple objects in 2007. Click on the Find & Select item at the far right of the Home tab, and the dropdown looks remarkably like your 2010 screenshot.

  5. Chandoo says:

    @Jon.. Thank you. Dumb me, I somehow thought we couldnt select objects in Excel 2007. Just saw the "select menu" and it is there. I have corrected the post and removed the point. I have added the "you can make your own ribbons" instead. Thanks once again.

    @Arti: what do you mean by make ribbons stick?

    @Alex: May be it is my installation, but when I go to "File menu" I see "recent files" by default.

  6. Arti says:

    For example, if I am working with one of the contextual ribbon menus (Pivot tables, Drawing/Chart etc), as soon as I click away from the selected object, the menu tabs vanish. If I click on the object again immediately, then Excel will remember what I was looking at, but if I wander away and click on a Pivot, then back again on the Chart, the menus will 'appear' but not get activated, thereby causing much annoyance and additional clicking.

    I want to "pin" the whole menu (not invididual commands) somehow, so that I can have the menu there for the length of the time I am working with graphics. Excel 2003 used to have the Drawing toolbar you could detach and hover while you were working, but this functionality disappeared in Excel 2007.

    My thought was Excel should just allow a 'pin', similar to the Recently Opened files menu, for the Ribbon Menus as well. If I have not selected any Drawing object, the commands can be greyed out, but I want the menu as a whole to 'stick'.

  7. Chandoo says:

    @Arti... I think MS solved this problem differently. When I select a pivot and go to "design" tab Excel 2010 remembers this and automatically takes me to "design" tab when I reselect the pivot.

    Apart from this you can also define your own ribbon with all the things you normally do. See the above article (I have added this after Jon's comments)

  8. Stephen says:

    Nice feature. About time for a upgrade for MS Office

  9. Arti says:

    Oh... okay. That might be a start. I'd probably just copy-paste the Drawing tab haha. Thanks. I'll definitely give Excel 2010 a try.

    Btw - have you considered getting into / gotten into the world of Excel as it meets SharePoint?

  10. Jon Peltier says:

    Actually, the replacement new thing is probably better than all the rest. One thing that the designers of the Office 2007 ignored was allowing regular users to customize their own interface. Office 2010's interface was expanded in this way to address the huge uproar.

  11. jeff weir says:

    Is there still a limit on how many things you can add to the QAT bar? (I'm too lazy to look myself.)

  12. Chandoo says:

    @Jeff.. it seems to take quite a few, but only shows one line and gives a little arrow button at the end. (summary: shucks!)

  13. Squiggler says:

    The best thing is you can edit the ribbon directly from excel, so now i can create my own bar with just the things I use regularly!

  14. John says:

    One of the annoying things in 07 for me is the Add-Ins menu bar - in 03 I could keystroke directly to menu add ins.. In 07 I needed an extra keystroke just to activate the add-in menu, then the keystrokes as normal.. Hope this marek sense..

  15. Jon Peltier says:

    John -
     
    If you remember the old Excel 2003 Alt-key shortcuts, you can still use them in 2007. To get to the Add-In dialog:
     
    Alt-T-I

  16. Gagan says:

    Dear Arti & Chandoo

    Seen your comments over some issues. Hope you are form India, gone through your comment expecting a pin to command it as a whole, great, hope if someone out of MS have read it, it may be kept in mind while the next R & D of Office Ver. 16

  17. Loranga says:

    Just incase someone forgot CTRL+F1 will collapse the ribbon.

  18. [...] was pleasantly surprised when I ran Microsoft Excel 2010 for first time. It felt smooth, fast, responsive and looked great on my [...]

  19. DK Samuel says:

    I like the sparklines, and the ability to modify the charts

  20. CHRIS LUNA says:

    How do you get rid of the advertisment on the right hand side? If you upgrade then will it take off the ads?

  21. Derek says:

    Once again Microsoft has re-decorated the Office and we are NOT pleased!

    The graphics object selector can be found in the Home ribbon under Find & Select, Select Objects near the bottom of the drop down. You can make it part of the Quick Access toolbar by right click over it and selecting Add to Quick Access toolbar.

    The graphics "cursor" will now appear on the mini-toolbar at the top left of the window.

  22. Vladimir says:

    How to get rid of "Add-Ins" button in Backstage (File)" menu by means of XML code, i.e. to hide, to delete or to disable this button?

    This button is usually situated in the Backstage menu between "Help" and "Options" buttons.

    • Pete Kies says:

      Vladimir, did you ever get an answer to your question?

      I am tying to customize the ribbon UI for a file using XML, and this is precisely the piece I can't figure out. I can hide other tabs, remove items from QAT and backstage - all except the options that are showing up under add-ins in backstage. If there is an XML syntax for referencing this thing and making it invisible, I cannot find it.
