Question

I don’t know how to hide the y axis only. I want the numbers to stay but remove the line. Do you know how to do that?

Answer 1

You can hide both axes this way:

renderer.setShowAxes(false);

You can hide the grid independently:

renderer.setShowGridY(false);

If the above is not enough, you can set the margins such as the Y axis is not visible and move the Y axis labels to the right:

renderer.setMargins(new int[] {20, -1, 10, 20});
renderer.setYLabelsAlign(Align.LEFT);
renderer.setYLabelsPadding(-10);
