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();
}

What you describe is a bug. The z-axis position is not preserved when zooming in the XY plane.
We will send you a modified QCChart3DNet DLL.
Also, when adding a grid in the XZ plane, use the following code, rather than what is in your example. Note that it specifies all three axes, and sets the GridAxisPlane to XZ_MINY_PLANE.
Grid zgrid = new Grid(xAxis, yAxis, zAxis, ChartObj.Z_AXIS, ChartObj.GRID_MAJOR);
zgrid.GridAxisPlane = ChartObj.XZ_MINY_PLANE;
chartVu.AddChartObject(zgrid);
