How to reduce the scale of GraphView to one?

问题

I want to reduce the scale of my GraphView to one.

I want to be displayed from 0 -> 15, one by one and not 0, 5, 10, 15.

This is what I have tried:

graphView.getViewport().setYAxisBoundsManual(true);
graphView.getViewport().setMinX(-15);
graphView.getViewport().setMaxX(15);

graphView.getViewport().setXAxisBoundsManual(true);
graphView.getViewport().setMinY(-15);
graphView.getViewport().setMaxY(15);

PointsGraphSeries<DataPoint> series = new PointsGraphSeries<>(new DataPoint[] {
        //Add DataPoint objects
});
graphView.addSeries(series);
series.setShape(PointsGraphSeries.Shape.POINT);

Hot can I solve this?
