Hello!

I have 2 tables that I want to input to the data to report node to generate a line chart with 2 lines, one table represents one line. Does anyone know how to do it??

Thanks!!

Hello,

I am unclear about where your problem exactly is. I will try few possibilities/solutions:

  • To produce 1 single table with 2 columns out of 2 with 1 column each, you  can use the Joiner node or the Column Appender node.
  • To produce a chart with 2 distinct lines out of the resulting table you can use for example the (JFreeChart) Line Chart node (other nodes may be suitable as well)
  • To send the resulting graph to a report as image you can use the Image to Report node.

Hope this helps, otherwise please describe more in details what doesn't work for you.

Cheers,
Marco.
