To increase the axes title size use multiRenderer.setAxesTitleSize()
. As for the axes label colors use multiRenderer.setXLabelsColor()
and multiRenderer.setYLabelsColor()
. The axis color can be changed with multiRenderer.setAxesColor()
.
Again, I encourage you to play with the settings of the renderer. In your IDE, type multiRenderer.
and all available methods will be shown. Scroll through those and you can probably find what you are looking. Most of the methods have clear descriptive names.
