  How to adjust plot area base on data

Hi All,

I often set the plotarea at (50, 50), but sometimes data if very large so 50 pixel not enough to display the large data label in y axis.

Like attachment, correct label should be "119.8689", but it looks like "19.8689"

Is there any way to adjust plotarea base on current data or fullRange?

Thanks,
zudeng

Hi zudeng,

You can use setPlotArea to provide an initial position and size for the plot area (you can use (50, 50) for your case). After entering all the data and configuring the chart, you can use XYChart.packPlotArea to adjust the plot area so that the axis labels will stay inside a given region. See:

An example is at:

Hope this can help.

Regards
Peter Kwan
