How to clip a series by its grid? - androidplot

Question

I want to create an XYPlot such that the most left point and the most right point of all series, are clipped off.
So, let's say I want to plot the series described by the following arrays
Number[] xs = new Number[]{-1, 50, 101};
Number[] ys = new Number[]{10, 20, 20};
But I want to clip off the first point (-1,10) and the last point (101,20), how could I do it?
I tried to use the methods setDomainBoundaries() and setRangeBoundaries() but the series exceeds it's grid/plot area.

I'd suggest a custom implementation of XYSeries to do this. Here's a example that should basically do what you want:
class MyXYSeries implements XYSeries {
Number[] xs = new Number[]{-1, 50, 101};
Number[] ys = new Number[]{10, 20, 20};
#Override
public int size() {
return xs.length - 1; // clip the trailing point
}
#Override
public Number getX(int index) {
// shift xy vals over one to clip the leading point
return xs[index+1];
}
#Override
public Number getY(int index) {
// shift xy vals over one to clip the leading point
return ys[index+1];
}
#Override
public String getTitle() {
return "your title";
}
}
