You could create a reference line for both views that is higher than any value in the measure. So for instance if the largest value in each is 800 and 900, you could create a reference line at 1000 in each view. Set the Ref line to not use a physical line and then set both axis from both views to have the same start value with the same ticks. If you have troubles, post your sample here and we can help more.
This will indeed work but it will be a bit manual for me as every day I will need to change this line. (No idea about the largest value, can be anything)
This is doable tho.
Any other way otherwise?
