GraphView drawing only specific axis labels at specific points

Question

I'm using graph view to draw an inputted quadratic function. I'd like to only include numbers on the axes where the curve intercepts them. Here is my code:

private GraphView graph;
protected void Solve(View view)
{
    graph = (GraphView) findViewById(R.id.graph);
    graph.removeAllSeries();

    double x,y;

    LineGraphSeries<DataPoint> curve = new LineGraphSeries<DataPoint>();
    for(x=-10; x<10; x+= 0.1) {
        y = (A*x*x)+(B*x)+C; // A B and C are values input by the user.
        curve.appendData(new DataPoint(x, y), false, 200);
    }
    graph.addSeries(curve);
}

I understand that I can remove all labels on the axes using:

graph.getGridLabelRenderer().setVerticalLabelsVisible( false );
graph.getGridLabelRenderer().setHorizontalLabelsVisible( false );

If this isn't possible, I don't mind leaving the regular labels on but I need to label the intercepts. My application already calculates the intercepts so I have all the values, I just need to display them.

Example of when I run it:
