How to correctly draw a Surface

[Bartlomiej]

I am trying to draw a Surface as in the attached figure 1.

The following is a snippet of code that adds these points. 

Ultimately, I want to get the effect as in the Picture marked with the symbol 2

Unfortunately, something like this arises in the program. Strange shapes merging at zero point

      

            var test = new List<DataSurface>();

            test.Add(new DataSurface() { X = 0, Z = 400, Y = 0 });

            test.Add(new DataSurface() { X = 20, Z = 350, Y = 0 });

            test.Add(new DataSurface() { X = 150, Z = 150, Y = 0 });

            test.Add(new DataSurface() { X = 240, Z = 70, Y = 0 });

            test.Add(new DataSurface() { X = 300, Z = 0, Y = 0 });

            test.Add(new DataSurface() { X = 0, Z = 400, Y = 50 });

            test.Add(new DataSurface() { X = 20, Z = 350, Y = 50 });

            test.Add(new DataSurface() { X = 150, Z = 150, Y = 50 });

            test.Add(new DataSurface() { X = 240, Z = 70, Y = 50 });

            test.Add(new DataSurface() { X = 300, Z = 0, Y = 50 });

            RowSize = 4;

            ColumnSize = 4;

            DataSurfaceValues = new ObservableCollection<DataSurface>(test);

Hi Bartlomiej,

Greetings from Syncfusion.

In surface chart, you can apply data in a grid table format, that contains the number of rows and columns as shown in the following table.

	Z0	Z1	Z2	Zn
X1	Y00	Y01	Y02	Y0n
X1	Y10	Y11	Y12	Y1n
X2	Y20	Y21	Y22	Y2n
Xn	Yn0	Yn1	Yn2	Ynn

We have checked your query and we would like to inform you that, you are using the 2 rows and 5 columns as per your data values. But you have defined it as 4 rows and 4 columns which caused the issue. You can declare the row size as 2 and column size as 5 which will fix your issue.
