Topic: Regarding bar charts: How to set bar size? Posted: 03 Jan 2008 at 11:31pm
Hi!
How can I make nice charts bars that keeps the same bar size, no matter of how many bars I have in one charts?
I have two images to illustrate my problem. The first is when I have many values, i.e. many bars. On the second, I have just two bars. The chart's height is constant, and the bar size is divided over that area.
I would like the bar size to be constant and the charts size should expand if I have many bars. Is this possible to do?

You can sort of do this. In the Chart Options, you can play with the Gap and Overlap values to modify the largest bar you can get. (In Chart Expert, you can also change the bar size with somewhat cruder control.) If you have enough bars that they won't all fit on the graph, though, Crystal will automatically shrink the bars to fit.
To the best of my knowledge, there is no way to alter the size of the report dynamically. It is what it is.

If all else fails, I have just added a feature to CRChart 3.1 to do exactly what you want. You specify a "virtual number of bars" and the graph always draws as if their were that many bars, even if your dataset is much smaller.
So charts with just one or two or three bars look just like charts with 15 bars, etc.
This is so new that it isn't even in our online demo's yet. But if you contact me at danw@threedgraphics.com, I'll get you a free evaluation to play with.
