add plots for accuracy and loss over all epochs in a separate view (always visible)

[gfrogat]

IMO we should actually replace the timeline with a plot of the loss- and accuracy-curves that can be also used for filtering

[mstreit]

good idea. would look similar to what we have in ThermalPlot.

@mstreit Just that we talking about the same thing, you mean this timeline?

[gfrogat]

we cannot keep the curves in the same location as the range on the y-axis would be too small --> plot dimension should be classic 4:3 ratio (matplotlib has a default of 8:6)

[thinkh]

@gfrogat Can you please post a sketch or screenshot of the matplotlib one?

[gfrogat]

should look somewhat like this, because that's what the ML-folks are used to

Accuracy cell was added with #189
