I'm wondered is the any graphing capabilities for custom events present in current version of WPT?

For example, I add the following lines to SimpleProvider example and would like to see value graph over time:

for (int i=0; i < 100; i++)
{
    EventWriteSampleEvt_INT32((i*10)%100);
    Sleep(10);
}

In XPerfView I could see only tick marks and values in "Table View". Not found a way for custom graphing at all.

In WPA I could put "Field 1" to "graphing area" in "Generic Events View Editor", but no graphing for this event occurred. It looks like it does not understand this type at all (it shows as "Field 1", but not as Prop_Int32 (like table view does) and does not contain Min/Max/... options like graphed events does.
