3D Bar chart with 0 value

[Don Mitchell]

I have a 3D Bar Chart with multiple series per category. Some of the categories have a value of 0 (zero) for some of the series. These show up as missing columns. Is there a way to have a colored shadow shown at the bottom of the chart where the column would be? I think this would be easier for a viewer to interpret than just a missing column.

I have turned on the feature that shows the values for the columns and that puts 0s where the columns would be, but it doesn't look all that good.

I can email an example picture if anyone wants to see what I'm talking about.

Thanks,
Don

Hi Don,

The method that needs modifying is the drawItem method in the VerticalBarRenderer3D class. I can see a test in there for rectHeight!=0.0 which prevents the bar from being drawn...but in that case, you probably still want to draw the bar3dTop shape.

I haven't got time to look at it more right now, but I'll add it to the to-do list...

Regards,

DG

Don,

I had this same problem, and I solved it by changing all 0.0 values to 0.1. This causes a minimal representation without too much rewrite of the code. The other thing I had to do was add a "minimum axis height" so that if ALL values were 0, that the 0.1 didn't go to the top of the chart. I set my minimum height to 10, for example, and things worked quite well.

I think the other suggestion,to change the draw method is the way to go, however.
