Meet our new guest author, Ian Huitson, or Hui.

Hui will share excel tutorials, implementations with us once a week. Please visit About – Hui to learn more about him.

This week I am going to introduce a method for allowing single points to be highlighted and interactively moved in Excel Scatter / X-Y Charts and Line Charts.

You will see a lot of these style charts in various places where you want to highlight various aspects of the chart to your audience. It is a great technique for complex scientific and engineering charts where you may have hundreds or thousands of points.

Introduction

Excel charting basically has 2 styles of charts with these being Y value vs X Value charts and Y value vs X Label charts.

Examples of the X Value charts are Scatter and Bubble charts. Examples of the X Label charts are Line, Column, Surface, Area, Radar and Bar charts.

The basic differences between these is that the former has a variable X Axis and the later has a fixed X-Axis spacing between subsequent data points.

Some members of the X Label charts can display a value-type X axis when the X entries are dates, ie: The X values are plotted proportionally to the dates they represent. These types include Line, Area, Column, and Bar (Thanx Jon)

Y value vs X value (Scatter Charts)

As these charts are plotting Y vs X directly onto the chart, it is simple to add a series which contains the points you want to highlight.

It is worth noting that chart series for Scatter Charts don’t have to have an equal number of entries in each series. We will use this add a new series with just one point.

Method:

Goto Pg1 of the sample file. Sample File

My Data is an X-Y set of data in B2:C41, each Y value in Column C is plotted on the chart against the corresponding X value.

To plot a single point it is a matter of adding a new data series to the chart

The new series will be the 2 cells at B43:C43

1. Setup 2 lookup cells

In B43 put the equation =OFFSET(B$1,$B$44,0)

In C43 put the equation =OFFSET(C$1,$B$44,0)

Note that both these formula retrieve  a value that is the value in the Cell Reference cell, B44, below B1 and C1 respectively.

2. Setup a Cell Reference cell

Put a value in B44 for now say 1

3.Add a new Data Series to the Chart

Right click on the chart and goto Select Data

Add a New Series

Series Name  Highlight

X Values  =’Pg1′!$B$43

Y Values  =’Pg1′!$C$43

4. Add a slider

The slider is already installed

5. Set the Sliders Cell Link, Min, Max and other details

You will now have a new data point which will be at point 1 on the chart

6. Format the New Data Series

Right Click the new point and Format Data Series

Select a larger Marker Size and make it a Bold Red to stand out

7. Add a data Label to the series

Right Click the New Series and select Add Data Labels

8. Format the Data Label

Right Click the New Series and select Format Data Labels

On the Labels Options Tab, Tick the X & Y values

Select the Label and change the Font to a Bold and Increase Size so that it stands out

Use:

As you move the slider the Highlighted point will move back and forwards across the screen and show both the location and X & Y Values of the data point.

How Does This Work?

The chart contains a second series consisting of a single point (x,y)  which has been formatted to make it stand out on the chart

The coordinates for the new point are retrieved from the My Data list by using an offset from the top of the list.

The offset retrieves its offset value from a Cell Reference cell which in turn is controlled by a slider.

Why use Offset instead of Vlookup or Index/Match?

We aren’t concerned with looking up the actual value of the highlighted point, we are interested in retrieving for example the 9th data point from the list and the the 10th or 8th as we move the slider. The Offset only cares about how far it has to go to get the value, not the value.

By doing this we can mix up the X values, as Scatter charts allow you to do, and offset will happily retrieve data in order and doesn’t care about duplicates or having sorted data. Type any values into the X Column and watch as the offset happily maintains the highlighted point.


Line Charts

As these charts are plotting Y vs the position of the value on the X-Axis, a slightly different method is employed to highlight a point of interest.

For Line Charts we will add a new series to the chart and then use a method for hiding the non-highlighted points  so that only the highlighted point is visible.

Method

Goto Pg2 of the sample file. Sample File

1. Setup a Cell Reference cell

Setup a Cell Reference cell by putting a 1 in D43

2. Add a New Data Series

Besides the sample data, add a new series Highlight

D1:  Highlight

D2: =IF(ROW()-1=$D$43,C2,NA())

Copy D2 down to D27, Don’t worry about the errors #N/A, you put them there.

3. Add a new Data Series to the Chart

Right click on the chart and goto Select Data

Add a New Series

Series Name – Highlight

Y Series =’Pg2′!$D$2:$D$27

Note there is no X Value as the Y values are plotted in order against the existing X Values

You will now have a new data point which will be at point 1 on the chart

4. Format the new Data Series

Right Click the new point and Format Data Series

Select a Bigger marker size and make it a Bold Red to stand out

5. Add Data Labels

Right Click the New Series and select Add Data Labels

Right Click the New Series and select Format Data Labels

On the Labels Options Tab, Tick the X & Y values

Select the Label and change the Font to a Bold and Increase Size so that it stands out

6. Add a slider

The slider is already installed

7. Set the Sliders Cell Link, Min, Max and other details

Use:

As you move the slider the Highlighted point will move back and forwards across the screen and show both the location and X & Y Values of the data point.

How Does This Work?

The chart contains a second series consisting of a Column of #N/A error messages and a single cell containing teh Y value for the corresponding data point

Excel ignores and doesn’t plot the cells with the error message and so only the highlighted cell is plotted

The coordinates for the new point are retrieved from the My Data list by comparing the current Row to the Cell Reference cells value and if they are the same retrieving the Y value, all others rows have an error message inserted.

The slider is connected to the Cell Reference cell and so when the slider is moved the Cell reference cell updates and the new highlighted cell retries its value.

Quick Tip #1:

You can change the highlight from a standard marker to pretty much anything you like

Insert an Icon on your worksheet, Insert Menu, Insert Icon

Format the icon as you wish, Color, Size and Copy the icon

Select the Chart and select the Highlighted data point and Paste

To apply the picture/icon to all points in a series select the series and paste

Quick Tip #2:

You can add multiple highlights using the same techniques described in this post ie: for showing Min and Max values.

Instead of linking the Cell Reference cell to a slider link it to the Minimum or Maximum value of the data: =Min(Range), =Max(range)

Checkout the example on Pg3 of the Sample File: Sample File

FUNCTIONS USED:

Offset: http://chandoo.org/wp/2008/11/19/vlookup-match-and-offset-explained-in-plain-english-spreadcheats/

Row: =Row() returns the Row number of the Current cell

=Row(M10) returns the Row Number of Cell M10 = 10

NA: = Returns the Error Message #N/A

    Would be considerably easier just to have a table with the variance shown.

  2. Jomili says:

    On Step 3, how do you "Add budget and actual values to the chart again"?

    • Chandoo says:

      There are a few ways to do it.

      Easy:
      1) Copy just the numbers from both columns (Select, CTRL+C)
      2) Select the chart and hit CTRL+V to paste. This adds them to chart.

      Traditional:
      1) Right click on chart and go to "select data..."
      2) From the dialog, click on "Add" button and add one series at a time.

      • Neeraj Agarwal says:

        One more way to accomplish it is just select the columns into chart. Press Ctrl+C and then press Ctrl+V

  3. TheQ47 says:

    Unfortunately, this doesn't seem to work for me in Excel 2010. The "Var 1" and "Var 2" columns cannot combine two fonts to display the symbol and the figure side-by-side.
    Secondly, there is no option to Click on “Value from cells” option when formatting the label options. The only options provided are Series Name, Category Name or Value.

    • Chandoo says:

      @TheQ47... the emoji font also has normal English letters, so if you use that font, then you should be ok. I am assuming your computer doesn't have that font or hasn't been upgraded for emoji support.
      Reg. Excel 2010, you can manually link each label to a cell value. Just select one label at a time (click on labels, wait a second, click on an individual label) and press = and link it to the label var 1 or var 2.

  4. Neeraj Agarwal says:

    I am using excel 2010, please explain how to apply Step 12

    Hi Chandoo,

    I just found your website, and really love it. It helps me a lot to be an Excel expert 😉

    Currently I am facing with a problem at step 11:
    Var1 Var2
    D30%
    A5%
    B0%
    B4%
    B7%
    C10%
    C13%
    D27%
    I42%

    Though at mapping table, I used windings, here formula uses calibra. How I can change it? I am able to change only the whole cell. In this case numbers will be Windings too.

    Thanks for your help!

    • Chandoo says:

      Hi Mariann... Welcome to Chandoo.org and thanks for your comment.

      If you wanted to use symbols from wingdings and combine them with % numbers, then you need to setup two labels. One with symbol, in wingdings font and another with value in normal font. Just add the same series again to the chart, make it invisible, add labels. You may need to adjust the alignment / position of label so everything is visible.

  6. […] firs article explains how you can enhance your charts with symbols. You can simply insert any supported symbol into your data and charts. To some extend you can […]

  7. Franciele says:

    You're a good person, thank you to share your knowledge with us, I will try to do in my work

  8. Ali says:

    Great visualization of variance. My question is that is this possible in powerbi?

    How would you go about it?

  9. NARUTO says:

    HELLO, WHY CANT I FIND VALUES FOR LABELS IN EXCEL 2013

  10. Amol says:

    Dear chanddo sir,

    What to do if we have dynamic range for Chart. How this will work. can you able to make the same thing works on dynamic range.

  11. Ricardo says:

    Sir Chandoo,

    Good Day!
    First, I'd like to say that I am very grateful for your work and for sharing all these things with us.

    I tried to do this chart but it seems that the symbols don't work with text (abs(var%),"0%") unless we keep the Windings font style.
    The problem is, it converts the text into symbol as well and you wont see the 0% anymore. I'm using Windows 7.

    Sir This is awesome chart, and very easy to made because of your way to explain is very simple , everyone can do. Thank you

    one problem i am facing, I hv made this chart , but when i am inserting data table to chart it is showing two times , how can i resolve this

  14. renuka says:

    in this chart when i am adding new month data for example first i made this chart jan to mar but when i add data for the apr month graphs updated automatically but labels are missing for that new month

    • Chandoo says:

      Hi Renuka,

      Please make sure the formulas for labels are also calculated for extra months. Just drag down the series and set label range to appropriate address.

  15. Justine says:

    So I am playing with the Actual chart here - but amounts are bigger than your - you have 600 as Budget - my budget is 104,000 - is there a way to shorten that I am unaware of

    thank you - I LOVE YOUR SITE

  16. Arvind says:

    Thanks for the tips and tricks on Excel. In the Planned versus Actual chart examples, you use multiple values (ex. multiple Categories in above). How can this be done when we have only 1 set of values? For example if I have only this:
    Planned Actual
    SOW Budget 417480 367551

    How can I create a single bar chart like the one above?

  17. JEREMIAH KOOL says:

    Thank you Chandoo.
    This one is just perfect for my Quarterly Review presentation on Operational Budget against Actual Performance for the Hospital I'm currently working with.

  18. Shawn says:

    Is there a way to make the table of data into a pivot table to be able to add a slicer for the graph due to many different categories and months?

  19. Mihail says:

    Hi, I tried to modify you template with something appropriate for me, and I found a problem. this template was modified by me started with excel 2010, then 2016 and finally 2019. Same thing - somehow appear an error - or didn't show the emoticons for positive percentage or doubled the emoticons for some rows. I suspect to be from excel. if is need it I can sand you my xlsx for study. Please help if you can.

  20. Saidatta Pati says:

    Hi Chandoo,
    Could you please check the Var Formula in Step1. You have mentioned budget-actual and when i did this i got different values but when reversed like actual-budget i got the actual value what you have demonstrated in step1.
    Please share your view.

  21. Dan says:

    This is a great chart (budget vs. actual). However, in trying recreate it, I cannot color in the UP Down bars individually, and they all become formatted with the same color. I'm using Office 365. Look forward to the feedback.

    Thanks.
    Dan

  22. sathik says:

    pls explain in detail step 7

  23. Arun says:

    While in the Excel sheet you have used following formula for Var
    Var = Actual - Budget
    But
    in the note, you have written
    Var = Budget - Actual

  24. aye myat maw says:

    Good Presentation and Data information.thank you so much chandoo.
