Hi,
I am using colorgrid for mapping with C#. xCoordinate, yCoordinate are coordinate array ,zValue is the value of x-y, c is different colors , programme is :

TChart2.Series(0).asColorGrid.IrregularGrid = true
for (int i = 0; i < MyDb.zValue.Length; i++)
{
UInt32 c = MyDb.allocate(MyDb.zValue);
TChart2.Series(0).asColorGrid.AddXYZ(xCoordinate, zValue, yCoordinate, "", c);
}
sometimes I can work out images,but sometimes I cannot, see attached. I checked the original data of black color in images, the color should not be black.I wonder if data are large(about 50000 records)
Now if I use addarrayXYZ(x,z,y) to replace addxyz to finish the same task. z represents color, how I define z in c#?

thanks,

Hello,

You may be interested in reading the explanation here about how to populate this type of series.

If you still find problems with it, please try to arrange a simple example project we can run as-is to reproduce the problem here.

Thanks in advance.

Yeray,
Thank you for your answer instantly. I find I cannot show the color rightly. I mark two points that show color incorrectly(see my images).
I give you a simple programme, Please help me to check it. I hope there were no black(or blue) bars in it.
I appreciate your great help.
thanks,
robinson.

Yeray,
Here is my programme. The colors on my image at my marked points should be the colors I marked. I donot know if I attached my programme successfully.
Merry Christmas,
Robinson
