Hi, we’re using 19.5.9872 (7th May 2019), and are seeing an error in graph drawing: when we choose “Graph Trend” on any graph (that I’ve tried so far), I just get “Error Drawing Graph”.

Showing the RRD command also shows the error:

                RRDTool Output: ERROR: invalid rpn expression in: 586400,-7,1800,inbits,PREDICT

 

(full output shown below)

Is this a known problem?

Thanks,

-Adam
