Pie chart with all zeros

[calimero100582Participant]

We want to draw a pie chart based on the usage data of certain tools with predefined ranges.

var data = [{Text: ‘Low’, Value: 0}, {Text: ‘Medium’, Value: 0}, {Text: ‘High’, Value: 0}];

the pie chart draw 2 sections at 0% and 1 at 100%.

Any way to get this special case to draw all 3 sections at 33.3%?
If I modify the data by myself, the tooltip would be incorrect.

Hello calimero100582,

An example on value/percentage use in a pie chart can be found in the forum topic Pie Chart section label to show John: 8000(20%). However, it would not be suitable in your case because it cannot be determined what part of 0 is 0 (division by 0).

We suggest you to manually modify the displayed values using the callback functions formatFunction and toolTipFormatFunction.

the formatFunction is useful for label, but do you know if there is a way to specify the size of the slice

Hi calimero100582,

The value field specifies the size of the slices. You may change your values to equal numbers, e.g.:

var data = [{Text: 'Low', Value: 10}, {Text: 'Medium', Value: 10}, {Text: 'High', Value: 10}];

and change the labels using formatFunction to display zeros.

I added a percent to my data for the label, and kept value for the tooltip
