We are trying to use Nevron Mesh Chart in our Application to display graphs between three quantities. The chart works perfectly fine when all the three quantities are numeric. The sample code snippet is:

            Nevron.Chart.NChart surfaceChart = nChartControl1.Charts[0];

            surfaceChart.Enable3D = true;

            surfaceChart.Projection.SetPredefinedProjection(PredefinedProjection.PerspectiveTilted);

            surfaceChart.Series.Clear();

            Nevron.Chart.NMeshSurfaceSeries surfaceSeries = (NMeshSurfaceSeries)surfaceChart.Series.Add(SeriesType.MeshSurface);

            surfaceSeries.Data.SetGridSize(4, 4);

            surfaceSeries.Data.SetValue(0, 0, 0.8, 0.0, 1.3);

            surfaceSeries.Data.SetValue(1, 0, 0.5, 12.7, 1.2);

            surfaceSeries.Data.SetValue(2, 0, 0.2, 15.0, 1.1);

            surfaceSeries.Data.SetValue(3, 0, 0.0, 17.0, 1.0);

            surfaceSeries.Data.SetValue(0, 1, 1.9, 5.0, 12.0);

            surfaceSeries.Data.SetValue(1, 1, 1.7, 10.0, 11.0);

            surfaceSeries.Data.SetValue(2, 1, 1.3, 18.0, 10.0);

            surfaceSeries.Data.SetValue(3, 1, 1.1, 28.0, 9.0);

            surfaceSeries.Data.SetValue(0, 2, 2.8, 2.1, 22.0);

            surfaceSeries.Data.SetValue(1, 2, 2.5, 11.0, 21.0);

            surfaceSeries.Data.SetValue(2, 2, 2.1, 20.0, 20.0);

            surfaceSeries.Data.SetValue(3, 2, 1.9, 22.0, 23.0);

            surfaceSeries.Data.SetValue(0, 3, 3.8, 2.1, 22.0);

            surfaceSeries.Data.SetValue(1, 3, 3.5, 11.0, 21.0);

            surfaceSeries.Data.SetValue(2, 3, 3.1, 20.0, 20.0);

            surfaceSeries.Data.SetValue(3, 3, 3.9, 22.0, 23.0);

The problem that we are facing is – if one or more graph axis are calibrated by string values, the mesh graph is *not displayed*. In other words, we want to render a Mesh graph between numeric value on Y axis and string values on X & Z axis. We tried doing that by the following code snippet, but the Mesh chart didn’t get displayed on executing the code.

            Nevron.Chart.NMeshSurfaceSeries surfaceSeries = (NMeshSurfaceSeries)surfaceChart.Series.Add(SeriesType.MeshSurface);

            surfaceSeries.Data.SetGridSize(3, 3);

            surfaceSeries.Data.SetValue(0, 0, (object)1.2, (object)"b", (object)"c");

            surfaceSeries.Data.SetValue(1, 0, (object)1.5, (object)"e", (object)"f");

            surfaceSeries.Data.SetValue(2, 0, (object)1.9, (object)"h", (object)"i");

            surfaceSeries.Data.SetValue(0, 1, (object)2.3, (object)"k", (object)"l");

            surfaceSeries.Data.SetValue(1, 1, (object)2.7, (object)"n", (object)"o");

            surfaceSeries.Data.SetValue(2, 1, (object)2.9, (object)"q", (object)"r");

            surfaceSeries.Data.SetValue(0, 2, (object)3.4, (object)"t", (object)"u");

            surfaceSeries.Data.SetValue(1, 2, (object)3.1, (object)"w", (object)"x");

            surfaceSeries.Data.SetValue(2, 2, (object)3.9, (object)"z", (object)"zz");

It seems like Object version of overloaded NMeshSurfaceData::setValue is not working for some reason. Could you please help us to figure out what’s wrong with the above code snippet?
