ltspice
In the above circuit I can only be able to plot |Vr1+Vc1| = V1 in green plot and Vc1 in blue plot. I use the voltage probe in LTSpice and click on the lines to obtain the plots. If I click on the line between V1 and R1 it plots |Vr1+Vr2| = V1. If I click on the line between R1 and C1 it plots Vc1.
Is there a way to see also Vr1 (the voltage drop only accross R1) along with the others?
Unfortunately, as mentioned in the comments, there is no way to do this in LTSpice. I recommend plotting the stepped waveform in one plot plane and then plotting the second waveform in a second plot plane. This way you can still see the relationship between the two waveforms while having the stepped waveforms be various colors.
Right clock on the DC voltage source and select Advanced. Then select PWL(t1 v1 t2 v2...) Select Additional PWL points. Fill in the table with your desired voltage steps and times. See example below:

Click on the left side of the component (cursor will be a red probe before, then turning gray), drag over the component to the right (cursor will be a black probe), then release the mouse button.
Now the graph shows something like
V(N002,N003)which is the voltage between those nodes. If you know the node names you can also manually enter these expressions into the graph view, or move things around or do calculations there.
