I printed a bar chart using JFreeChart. But if I want to make the bars closer to each other using setCategoryMargin(-2) on my CategoryAxis, the Bar Chart appears to align in the center.
Is there a way to align the entire graph to the left, so it's directly next to the y-axis ? Or reduce the space between the bars without the chart getting centered ?
The setCategoryMargin(float) is used to adjust the space between categories and accepts a value between 0.0 and 1.0 (where 1.0 means 100% of the available space is used as the margin(!)). So using a negative value (-2) may not give the expected result.
You can try setting different lower positive margin to to see what suits your needs.
