Hello,
You can use the Data Zoom tool in order to zoom-in on a portion of a chart interactively (with the mouse). You can take a look at the following example in our demo application:
All Examples > Interactivity > Tools > Data Zoom Tool
By default the chart in the example is 2D, but there is a setting to switch it to a 3D point chart. In general this method applies for all Cartesian series, including surface series.
The same thing can be achieved programmatically. The code below demonstrates how to zoom-in on a portion of a mesh surface:
nChartControl1.Controller.Tools.Add(new NSelectorTool());
nChartControl1.Controller.Tools.Add(new NTrackballTool());
NChart chart = nChartControl1.Charts[0];
chart.Enable3D = true;
chart.Width = 50;
chart.Depth = 50;
chart.Height = 40;
NMeshSurfaceSeries surface = new NMeshSurfaceSeries();
surface.Data.SetGridSize(10, 10);
chart.Series.Add(surface);
for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 10; j++)
{
double y = Math.Sin(i * 0.3);
double x = i;
double z = j;
surface.Data.SetValue(i, j, y, x, z);
}
}
NAxis axisX = chart.Axis(StandardAxis.PrimaryX);
axisX.ScaleConfigurator = new NLinearScaleConfigurator();
NNumericAxisPagingView pagingViewX = (NNumericAxisPagingView)axisX.PagingView;
pagingViewX.Enabled = true;
pagingViewX.Begin = 1;
pagingViewX.Length = 2;
NAxis axisZ = chart.Axis(StandardAxis.Depth);
axisZ.ScaleConfigurator = new NLinearScaleConfigurator();
axisZ.Visible = true;
NNumericAxisPagingView pagingViewZ = (NNumericAxisPagingView)axisZ.PagingView;
pagingViewZ.Enabled = true;
pagingViewZ.Begin = 1;
pagingViewZ.Length = 2;
