how to control the width of the columns of the bar chart

[zhengyu xia]

I create a bar chart has two columns , the columns are very wide
I want to reduse the width of column how to do it

[David Gilbert]

There is no direct control over the width of the bars, they use up the available space after the gaps have been distributed.

In 0.9.4, you can use the setCategoryGapsPercent(...) and setItemGapsPercent(...) methods to increase the amount of space between the bars. And the setIntroGapPercent(...) and setTrailGapPercent(...) methods to control the space before the first bar and after the last bar. All in the CategoryPlot class.

This control has been passed to the CategoryAxis class in 0.9.5...
