 Stacked Bar Chart with "variable" numbers of stacks |

Is this possible? I'm not sure how to change the data...
// The data for the bar chart
double[] data0 = {100, 115, 165, 107, 67};
double[] data1 = {85, 106, 129, 161, 123};
double[] data2 = {67, 87, 86, 167, 157};

Hi MarkZB,
If the overall coloring scheme of the stack bars follow a fixed sequence, you can use one dataset per stack. It is possible that some bars would not have some stacks by setting the values of those segments to 0 for that bar.
If the colors of the bars are entire independent, you may consider to just use put each bar in a separate bar layer. In this way, each bar layer only has one bar, and you can use one dataset per segment. For a bar, if your code put the segment values and their colors in two arrays, you can use something like:
BarLayer layer = c.addBarLayer2(Chart.Stack);
layer.setXData(new double[] {0}); // the x-position of the bar
for (int i = 0; i < data.Length; ++i)
layer.addDataSet(new double[] { data[i] }, color[i]); // one dataset per segment
The above is for a stacked bar at x = 0 (the first label position). You can use the same method to put a bar at x = 1, 2, 3, ... with different data and color arrays.
Hope this can help.
