- Part 4: Pulling it all together
In this post we are going to look at a simple example of the VBA behind the Dynamic Dashboard. Essentially we will learn to write macros for doing this:
The dynamic dashboard VBA example can be downloaded here [Mirror]
Some VBA essentials
Defining variables:
First we need to define variables “left” and “top” as integers.
Dim left As Integer
Dim top As Integer
Next we need to set a value for these variables. To do this I have created two named ranges in the Excel file called Left and Top. To make variable “left” equal to named range Left:
left = Range("Left").Value
and the equivalent for variable “top”
top = Range("Top").Value
Finally select the shape:
ActiveSheet.Shapes("Rounded Rectangle 1").Select
And define its position:
Selection.ShapeRange.top = top
Selection.ShapeRange.left = left
So the full code is:
Sub move_Image()
Dim left As Integer
Dim top As Integer
'Define the position values
left = Range("Left").Value
top = Range("Top").Value
'Select the shape and position it
ActiveSheet.Shapes("Rounded Rectangle 1").Select
Selection.ShapeRange.top = top
Selection.ShapeRange.left = left
End SubThis code can be viewed by clicking on macros in the file.
Once you have the code ready, you should assign it to the Rounded Rectangle 1, so that whenever you click on the rounded rectangle, the code is run.
What it does
In the downloadable file in Sheet1, enter values against the Top and Left positions in the input area (blue). Click on the shape to move it to the position you have defined.
How it works
Clicking on the shape runs macro “move_Image”.
The value for the position of the shape is linked from the named range to the variable.
The macro uses Selection.ShapeRange.top and Selection.ShapeRange.left to determine the position of the shape based on the variable value.
What Next?
We now know how to move objects using VBA. In the final part of the series learn how to pull all this together to create the dashboard.
Download the complete dashboard
Go ahead and download the dashboard excel file. The dynamic dashboard can be downloaded here [mirror, ZIP Version]
It works on Excel 2007 and above. You need to enable macros and links to make it work.
Added by PHD:
Myles has taken various important concepts like Microcharts, form controls, macros, camera snapshot, formulas etc and combined all these to create a truly outstanding dashboard. I am honored to feature his ideas and implementation here on PHD. I have learned several valuable tricks while exploring his dashboard. I am sure you would too.

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!
Whyyyyyyyy?
The idea is to tell how to make a bubble chart. I got an e-mail from a reader recently asking how the scatter bubble is made. So I thought a 15 second tutorial would be a good idea to show this.
Did that email go "Dear Chandoo, I know that you scorn bubble charts, but if I don't do one in Excel for my boss then he'll fire my sorry ass, and my children will have to be sold for medical experiments in order for me to be able to afford the upgrade path to Excel 2010"?
If so, fair enough...it's all in the greater good 😉
Chandoo,
I am using excel 2003 and it is not working. The x axis is not the one that I enter in x axis column. Please help! Thanks.
Sorry, after few attempts, I managed to get the right result. I shouldn't select the title (header) of the table and select only the data to produce the right bubble chart.
What's wrong with bubble charts? Is there a better method for displaying scatter plots with lots of overlapping data points? Don't tell me you'd rather jitter!
@Sanwijay: Cool.
@Precious Roy: There is nothing wrong with bubble charts. Infact, it is the only way to show 3 dimensional data (x,y and sizes) without confusing your audience. Jeff is worried that people might misuse the chart. As with any chart, bubbles also have a place and time for using them.
I recommend using bubble charts to show relative performance various products in several regions and similar situations.
Also, human eye is notorious in wrongly estimating the bubble sizes (as we have to measure areas). See http://chandoo.org/wp/2009/07/28/charting-lessons-from-optical-illusions/
We can partially improve bubble charts by adding data labels, but if you have too many bubbles, the labels will clutter the chart and make it look busy.
I can't seem to find a way to plot more than ten bubbles on a chart and need to know how to add more
@KW.. why would such a thing happen. I am sure you can add more bubbles that that. Can you tell us exactly what you are doing...
Example table:
A B C (size)
Me: 25 30 15%
Him: 30 22 11%
Her: 12 30 20%
I am trying to make a bubble chart where the Y axis is A, the X axis is B, and the size of the bubble is C. There should be only 3 bubbles. I keep ending up with six (with the labels being only "Me" and "Her"). My goal is to have three bubbles, one representing each person. Clearly I am doing something wrong. Can you help explain...?
Hi,
I wanted to add data labels to the bubbles. Each bubble represents a different company name. Excel allows me to add the size, legend, x axis values and y axis values. How do I add instead- Company A, B, C, D for the bubbles?
youon you have to choice every data for every company..
ex:create bubble for A company,after that click right> add data label> adjust data labels :format data labels and choose : series name.
i hop u will succeed .
[...] we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target [...]
If we want bubble size to be controlled by one column, but the bubble labels to be controlled by another column, how can this be achieved?
many thanks!!!!
