Feature to change ordinate min/max range

In this chart you can see the spike in the beginning - slope from 117% to -121%. Because of it ordinate scale set to -121 to +100%. And because of that whole rest of slope chart is useless - it's just too small to read it.

The ordinate scale does not change even if I zoom in the abscissa to make spike go out of view range.

I find that this case if pretty common, and I often cannot read charts, just because of single spike (btw, sometimes spike are just gps/maps glitches).

Would be great to have a feature to zoom ordinate scale.
