I'm using this plugin to record my cppCheck and Gcc warnings and it's pretty cool.

But I didn't find in the plugin options if it's possible to show the delta (as integer) of those counters between 2 builds may be in this view :

I can see it in the trend graph but when starting with a project that contains numerous warning (cppcheck for exemple), the delta is not visible in a graph that contain +1500 errors so a number would help. I'm clearly aware that when my cppCheck warnings will be low (< 20) I will be able to see them in the graph.

But for the gcc exemple, we see that we introduce a new warning with the graph but it is less obvious than having a delta number displayed clearly. 

I seems that there is new feature but it doesn't detect the new one :

Nor in the new panel :
