Show outer labels in a pie chart?

Hi there,

I'm trying to create a pie chart with the JS library and I am having a problem how to show the outer labels.

I set them in the construcotr:

var series = new PieSeries(myValues, null, new Collections.List(["t1", "t2", "t3", "t4", "t5"]));

I have no errors, the pie shows but no labels. Is this a bug?

Hi,

The pie chart draws only inner labels by default. You can specify you want to show all label kinds supported by the series like this -

Code
Select All
pieChart.showDataLabels = Charting.LabelKinds.All;


LabelKinds allows bitwise combination where you could enable / disable individual flags to show specific labels -

Hi,

The labels show now, thanks. Is there a way to increase the font size?

Hi,

There are various fontSize properties provided by the Theme class. For data labels set this -

Code
Select All
pieChart.theme.dataLabelsFontSize = 12;


Here's a list of other Theme properties you could set for the chart -
