Hi, 

I tried to add a line chart to a composite chart and this line chart is bound to a datatable.

after i set the datasource of a series, this chart was blank...

I found some examples about to add line charts in composite chart, but they add points in code, not bound to a datatable.

Would you please show me a example about how to add a line chart that bound to a datatable to a composite chart?

the datatable like this:

                      A100    A200  A300  A400  A500

TypeA             10        14        8        -10     -5      

TypeB            15         5          -5       -3        0

I tried to draw two lines in this chart and will add other charts in this composite chart. 

thanks a lot.
