[SOLVED] Graph with no Data

I have a graph that I want to show a special message when there is no data. My research to date shows that I must perform a table request first to see if &LINES EQ 0. Then if there is data, I run the Graph report, otherwise show my HTML custom error page.

I am looking for a way to accomplish this more efficiently, since I am running two passes if there is data.

Thanks in advance.

You can do the graph, let it create an empty graph and hold it. Then check &LINES (it will be 0 for an empty graph) and take action upon that - either show the held image or show some empty graph message.
