Hello,

I've combined both the rotate and zoom examples and I'm having trouble when the user zooms in, the z axis disappears. It is especially noticeable when the user rotates the chart then zooms in.

I have inserted the code below, I haven't been able to find a solution for this. I've noticed there is no SetZoomEnable for the Z Axis, I'm not sure how SetZOrder would be used or whether its the solution to the problem.


If you could point me in the right direction I appreciate it. Thanks for your time.



public partial class ChartControl : ChartView
    {
        CartesianCoordinates pTransform1;

        private class ZoomWithStack : ChartZoom
        {

            public ZoomWithStack(ChartView component, CartesianCoordinates[] transforms, double zpos, bool brescale) :
                base(component, transforms, zpos, brescale)
            {
            }

            public override void OnMouseDown(MouseEventArgs mouseevent)
            {
                if ((mouseevent.Button & MouseButtons.Right) != 0)
                    this.PopZoomStack();
                else
                    base.OnMouseDown(mouseevent);
            }
        }


        public ChartControl()
        {
            // This call is required by the Windows Form Designer.
            InitializeComponent();

            // TODO: Add any initialization after the InitializeComponent call
            InitializeChart();
        }

Hello, I've posted this question in the wrong forum. Apologies.

Should i repost the question in the QCChart3D for .Net forum?
