Hi

Would it be possible implement the following features to the temp graph?

*Feature request 1*

**It would be good if there is way we can mouse over the temp graph
e.g. the heat bed graph or the hotend etc
and find out how long it actually took to heat up to the bed from 0 to 100 etc..**

Right now when we mouse over the curve of the temp graph,

we can find out how much degrees it was at that point of the curve

but there is no time code/duration at that point in the graph. so we don't know the exact time it took to reach that temp or how long a certain temp was maintained on the graph..

Yes, there is that -Xmin time axis on but it is hard to know the exact value of that time..

Also why is the X axis written with a negative minutes on the graph? e.g -24 min

It seems to be more confusing to understand since we tend to see time values to be positive, not negative on a graph.

*Feature request 2*

**click two points on the graph line (marked with an X) will show the exact time duration between those two points click**
