The problem is that I have this nonlinear graph but there is a single value in it meaning that the value before my value is null, then comes this point and after the value is null again. I have read that it is not possible there: https://infragistics.com/community/forums/t/10025.aspx , but I hope that there is a workaround or something that can help to solve my issue.
Thanks a lot
Hi Sam,
In order for any line to be drawn, the Line chart requires two consecutive non-null values.
Max did provide some workarounds in the thread you linked that you may be able to use. The first one is to use a Scatter chart instead, and set the ConnectWithLines property to true. His second workaround involved drawing the point in manually (he provided some code for this).
Please let me know whether Max's workarounds can be used in your application.
thanks the scatter chart with the same data in another layer worked for me since the composite chart is used
