I'm creating a graph with MeterPlot in which I need 6 static values. It turns out that the graph cuts the top part and the part of the sides; how do I reduce that area? I already tried with this:

public void draw(Graphics2D g2, Rectangle2D chartArea, Point anchor, ChartRenderingInfo info) {
    chartArea.setRect(chartArea.getX(), chartArea.getY(),
        chartArea.getWidth(), chartArea.getHeight() + 50);
    super.draw(g2, chartArea, anchor, info);
}

It doesn't work for me. As you can see, the image comes out cut off; I need it to come out central.

A `MeterPlot` works best with an outline stroke < 10. – trashgod Mar 03 '22 at 23:41
Hello, thanks for answering, yes, but if I place < 10, the color line is very thin and I need it more or less that thickness. @trashgod – Rosmarys Morao Mar 04 '22 at 18:19
This [approach](https://stackoverflow.com/q/70692566/230513) is an alternative. – trashgod Mar 04 '22 at 18:46
Yes that is the approach I am following, but I am not able to reduce the area of the circle so that the sides do not intersect – Rosmarys Morao Mar 07 '22 at 13:02
You'll need either a custom `MeterPlot` or a custom `DialScale`. – trashgod Mar 07 '22 at 13:22
meterplot works for what I need, what I need is to reduce the area of the circle or if there is a way to enlarge its space so that the circle is not cut – Rosmarys Morao Mar 08 '22 at 19:02
You could alter the clip in `MeterPlot::draw` or the stroke in `StandardDialRange::draw`. – trashgod Mar 08 '22 at 19:57
I am using the meterplot.draw, but no change occurs – Rosmarys Morao Mar 17 '22 at 17:38
