Pie chart with single data element throws error

[guest]

A pie chart that is created with only a single data element throws the following error:

t.run has no properties - Pie.js (line 121)

Here is an example chart which produces this error (note the single data element in "Series A"):

var chart1 = new dojox.charting.Chart2D("test1");

chart1.setTheme(dojox.charting.themes.PlotKit?.blue);

chart1.addPlot("default", {type: "Pie"});

chart1.addSeries("Series A", [4]);

chart1.render();

#7124 is the dup of this ticket.

Solved looking at others .js in plot2d. Is it correct?

(In [15168]) gfx: fixing degenerated pies (no series, empty series, all non-positive, only one value, only one positive value), a test case was added as well. Fixes #7234. Fixes #6982. !strict

Replying to elazutkin:

Thanks very much for your correction, is perfect !.

This case even if seems to be not important, see the following usage for example:

I have a tree, each node is a task, each task have a certain period of time, displayed as a pie.

I am displaying in the pie, the nodes in the same level (each node in level n is recursively the sum of its children), clicking inside a pie portion will bring the next level also displayed as a pie.

The following case is real:

node_A (50%)

node_AA (100%)

node_AAA (30%) node_AAB (40%) node_AAC (30%)

node_B (25%) node_C (25%)

clicking on node_A will give you a 100% node_AA, clicking on node_AA will display the pie-> node_AAA,node_AAB and node_AAC

thanks again, the 2D graphics is excellent, and is a very important addition to Dojo '''
