I would like to erase the "0" label on the vertical axis so it does no longer intersect with the horizontal axis. I tried to change "Major ticks-> first tick" to "1" but it did not work for me.
By default Origin automatically determines if the axis begin and end shows or not.
To hide axis begin or end, double click the Y axis to open Axis dialog. Go to Special Ticks tab. On Axis Begin row. Click the Auto in Show column and choose Hide.
