Hi Richard, in the rrdgraph.pod there is the following section
=head2 graphv Calling rrdtool with the graphv option will return information in the rrdtool info format. On the command line this means that all output will be in key=value format. When used from the perl and ruby bindings a hash pointer will be returned from the call. When the filename '-' is given, the contents of the graph itself will also be returned through this interface (hash key 'image'). On the command line the output will look like this: print[0] = "0.020833" print[1] = "0.0440833" graph_left = 51 graph_top = 22 graph_width = 400 graph_height = 100 image_width = 481 image_height = 154 value_min = 0.0000000000e+00 value_max = 4.0000000000e-02 image = BLOB_SIZE:8196 [... 8196 bytes of image data ...] There is more information returned than in the standard interface. Especially the 'graph_*' keys are new. They help applications that want to know what is where on the graph.
