In a scenario where two numeric axis (X, Y) both have IsCenterAxis set to true, is it then possible to force MouseWheelZoomModifier to use center point of current view when zooming, rather than using mouse point as center point when zooming ?

Hi Arne,

We discussed your inquiry and prepared a custom Chart Modifier which will keep your chart centered while zooming. Please take a look:

    public class CustomMouseWheelZoomModifier : MouseWheelZoomModifier
{
    protected override void PerformZoom(Point point, double value)
    {
        var viewportPoint = new Point(ModifierSurface.ActualWidth / 2, ModifierSurface.ActualHeight / 2);

        PerformZoom(viewportPoint, value, value);
    }
}

You can find more info regarding the ModifierSurface area in the “Transforming Coordinates to the Viewport” section of the following documentation article:
Custom Modifiers – ChartModifierBase API
