Using tmsh to Get a Specific ASM Chart

Thanks boneyard, I can get it to send out reports via the GUI (pre-defined ones and multi-level ones) but not that specific report unfortunately.

I was hoping I could use tmsh syntax along the lines of:

show analytics application-security report view-by violation drilldown { { entity severity values { Error } } }

But I can't quite work out how to put the syntax together for the specific chart I'm after
