Doughnut Chart / Spiral Chart
A couple of posts back I demonstrated how to create a box chart. Here is thepost.
Today I wanted to demonstrate how to display the same data as a spiral graph. What’s a spiral graph you ask? Basically it’s a doughnut chart. Let me show you… In the above example I compare 3 leaf blowers based on Satisfaction, Price and Durability. Each category and item is separate. Well for the spiral graph I want to compare each category separately. I want to compare all three blower types for Satisfaction in one graph, Price in a second and Durability in a third.
To start my spiral graph I go to my data tab. For the green leaf blower I have the following data. The first column of numbers is the results of the survey. The second column of numbers is 100 – the first column (100 – 53 = 47). I need both of these numbers (53 and 47) to create the first spiral of my graph.
So I start by highlighting Satisfaction, 53 and 47. Then I choose Insert > Other Charts > Doughnut Chart
This creates my first spiral in the doughnut chart.
Now I want to change the blue of the doughnut to match the green color of the Satisfaction bar chart. I select the blue by mouse clicking on it. Now you may find that when you click on the blue Excel selects both the Blue and Red colors. No big deal, just click on the blue a second time and try again.
From the format tab, change the shape fill to be green.
Repeat the process for the red portion of the doughnut but select no fill instead of a color.
When Done I have my first section of my chart.
Now I can clean up the chart by removing the legend to the right by clicking on it and hitting the delete key.
Next I want to add the Yellow Satisfaction to my chart. I right mouse click on my green spiral and choose Select Data.
This opens the Select Data Source dialog. Click the add button. For Series name select cell A20 and for series value enter =Data!$B$20:$C$20
This adds the second spiral to the chart. I repeat the process above to change the color blue to yellow and no fill on the red portion.
Finally again I repeat the Select Data and add the red Satisfaction data.
I modify the blue color to be red and no fill the other section.
I am now left with my spiral graph.
I add the chart title “Satisfaction” by selecting Chart Title centered Above Chart from the Layout tab.
Now I can add a black edge to each color in my chart if I wish by using the Shape outline option just below the shape fill shown above.
Next I cut my chart moving it from the data tab to my Dashboard tab and resize it.
I repeat the above process for Price and Durability. When done I have displayed my results two different ways, by bar chart and by doughnut chart (spiral graph).
To add some additional detail I add text boxes for numbers and a line and circle from the Insert tab > Shapes.
How can you use the above techniques to add some wow to your next dashboard?
