Given a mouse position on a Cartesian chart, I can transform the point into a chart point using the following code:
protected NPointD TransformMousePositionToChartPoint(NMouseEventArgs e)
{
var view2Scale = new NViewToScale2DTransformation(this.cartesianChart, (int)StandardAxis.PrimaryX, (int)StandardAxis.PrimaryY);
var scalePoint = new NVector2DD();
view2Scale.Transform(new NPointF(e.X, e.Y), ref scalePoint);
var transformedPoint = new NPointD();
transformedPoint.X = scalePoint.X;
transformedPoint.Y = scalePoint.Y;
return transformedPoint;
}
Can I do the reverse? Given a point on the chart, can I transform it into a mouse position? If so, how?

Hi, Yes, you can do the opposite transformation using NScale2DToViewTransformation: NScale2DToViewTransformation transform = new NScale2DToViewTransformation(chart, (int)StandardAxis.PrimaryX, (int)StandardAxis.PrimaryY); Let us know if you have any questions.
