SharpPlot.DrawResponsePlot Method
Draw 3D grid, and construct surface from multiple vectors of zValues giving rows and columns.
Example
respdata = new int[][]{new int[]{4,3,2},new int[]{7,6,5},new int[]{12,11,10},new int[]{19,18,17}};
sp.ResponsePlotStyle = ResponsePlotStyles.WallShading|ResponsePlotStyles.GridLines|ResponsePlotStyles.Markers|ResponsePlotStyles.TiledSurface;
sp.SetMarkers(MarkerStyle.Node);
sp.SetAxisStyle(Color.Gray,LineStyle.Solid,0.5);
sp.SetFillStyles(FillStyle.Opacity30);
sp.DrawResponsePlot(respdata);
The short tutorial shows a few of the possibilities and some sample code.

Description
This chart is almost always used to illustrate a computed mathematical surface, and could often be combined with a Cloudchart to show a theoretical model overlayed with raw data values.
In the simplest case it takes a rectangular array of arrays of Z-values (effectively a matrix) and treats these as a uniform mesh to be plotted vertically with equally spaced x and y values. An option is to provide either or both of the x and y values as arrays of the correct length, to draw the mesh on a non-uniform scale.
By default the surface is drawn as a simple wireframe, but an option is to ‘tile’ the surface to give the illusion of a solid figure. This is often done with semi-transparent tiles so that surfaces with folds remain partially visible, whatever the viewpoint.
