How can I change the scale of the HR chart?

Is there an option to change the scale of the HR chart of an activity?
Today I did a run with some hill repeats and the HR chart is looking like this:

And I want it to look like the HR chart on Strava:

The HR trace started off with two zeros which messed up the scale. I edited those out but will sort out a fix for future activities (HR zero obviously bogus!).
