#40 getBounds() entries return null after a bar with height 0

[Bernd Hufmann]

I'm creating a bar chart series where some bars have height 0. This causes the getBounds() method on IBarSeries to return null for all bar entries in the array after the bar entry that has height 0. This is due the following lines in BarSeries:
...
for (int i = 0; i < xSeries.length; i++) {
if (cnt < comporessedXSeries.length
&& comporessedXSeries[cnt] == xSeries[i]
&& compressedBounds[cnt].width != 0
&& compressedBounds[cnt].height != 0) {
rs[i] = compressedBounds[cnt++];
}
}
...

Once one of the conditions is false the cnt is not incremented anymore (see cnt++ in if clause) and rs is not filled at the following indexes.

I added a patch with a fix (BarSeries.java.patch) that works in my use case. Please have look and let me know if this is ok.

I provided also an example to demonstarte the problem (BarBoundsExample.java). Run this example and hover over the bars right beside the one that have height 0 and for these beside the tooltip is not shown due to the error above.

Thanks
Bernd
