REQUIRED INFORMATION Ext version tested:

Clicking on the legend items in a radar chart does not toggle visibility of the corresponding radar surface. The legend item is always black and does not assume the color of the surface.

Steps to reproduce the problem:

In the ST 2.1.0 rc2 documentation extend the example of Ext.chart.series.Radar with

legend: { position: 'top' }, .
Click on legend item, corresponding surface does not vanish.

The result that was expected:

radar surface visibility changes

The result that occurs instead:


Test Case:

var store = new Ext.data.JsonStore({
fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
data: [
{'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
{'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
{'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
{'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
{'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}

var chart = new Ext.chart.PolarChart({
legend: {position: 'top'},
animate: true,
interactions: ['rotate'],
store: store,
series: [{
type: 'radar',
xField: 'name',
yField: 'data4',

Isn't that the same as http://www.sencha.com/forum/showthread.php?247129 only different series?

Not quite the same, it's a Ext.chart.PolarChart vs. a Ext.chart.CartesianChart.
The legend also does on pick up the color of the series, which it does for line charts.
