Hi.. I am new to chart FX, and I need to develop an Web Chart using chart FX.

I have following codes, but hits an error on line 3:

System.NullReferenceException: Object reference not set to an instance of an object.

I found the online sample coding (Softwarefx's Website), but it does not solve it. Is there any sample help code that I can refers to?

In my project, I included the ChartFX.WebForms.dll

Please advice.

Line 1: Imports

ChartFX.WebForms

Line 2: Dim

Charts As ChartFX.WebForms.Chart

Line 3: Charts.Data.Series = 2

Line 4: Charts.Data.Points = 5

Line 5: Charts.Series(0).Color = System.Drawing.Color.DarkGreen

Hi,

Have you dropped the chart control onto a form? Additionally, I noticed you are specifying a color for a series that does not exist yet (Line 5). This may be the line causing the problem. You need to define (add) the actual series to the chart before attempting to access it in the Series Collection (chart.series(0)....  cannot be accesed if this series has not been added).

Regards,

RandyJ
