Hello Arsen,

Thanks for writing.
Please consider this example:

public class CustomCategoricalAxis extends CategoricalAxis {
    public CustomCategoricalAxis(Context context) {
        super(context);
    }
    @Override
    public void renderLabel(Canvas canvas, ChartNode dataPoint) {
        RadRect layoutSlot = this.getLayoutSlot(dataPoint, this.lastLayoutContext);
        Paint yellow = new Paint();
        yellow.setColor(Color.YELLOW);
        canvas.drawRect((float)layoutSlot.x - 20.0f, (float)layoutSlot.y, (float)layoutSlot.getRight() + 20.0f, (float)layoutSlot.getBottom(), yellow);
        super.renderLabel(canvas, dataPoint);
    }
}

You can use this custom axis instead of the base CategoricalAxis class.
You can tweak the width with those magic numbers added to left and right. Also, there is bug in the label layout that causes them to stick a little bit above their layout slot. This will be fixed in our next release.

Please write again if you have more questions.
