CFChart not displaying all chart data items

Question

I am having an issue with ColdFusion's CFChart tag. I have a couple graphs that do not display properly. For a horizontal bar chart, when attempting to display 50 or more chart data items, the graph's bar labels stop plotting, but keeps plotting the bars themselves once it gets to bar number 50. I noticed making the chart height larger makes the issue worse as well. If i go from 1000px pixels to 2000px, it stopped plotting labels even sooner. The query that populates the chart items do not return blank label names either. See the screen below, the labels should keep plotting after "7 to 1".

I am running on ColdFusion 8 Developer Edition. Is this a possible limitation for ColdFusion's native charting capabilities? Or should I consider checking out Flex Charting instead?

Thank you!

Sorry - I banged away at this for a while, and couldn't get it to work. I tried recreating the issue in the Chart Editor. I modified the default data to have more than 50 columns but I was unable to reproduce the issue. I therefore thought it was your style. I noticed htat this line:

labelStyle isHideOverlapped="false" orientation="Horizontal" isMultilevel="true"

Was the main culprit. You remove it and you saw all the labels - but they were hard to read because of their orientation.

Ahah - try this:

labelStyle isMultilevel="true"

It isn't oriented right, but seems to work.
