1. Time series tick label overlap problem jfree.orgI have a lot of data points in a time series chart, and the problem is that the time labels on the domain axis (x-axis) displayed horizontal and they overlap , making the labels unreadable. Is it possible to tick labels in an angle or vertical? I am new to the jfreechart, and really appreciate your help. |
2. Time series tick label overlap in PDF-embedded chart jfree.orgI create PDF reports using JasperReport library, which uses JFreeChart capabilities. It works great but in some cases tick labels of time series X-axis overlap. I know that there is an auto-tick unit selection mechanism in JFreeChart. Could this mechanism fail when rendering charts for PDF? Is there any way to rarefy tick labels not switching auto-tick off? |
