In the line plot example: if I just add one point at the y-axis of 0 (mydata3 point 2), no data point goes below 0 yet the y-axis extends beyond 0 and looks unpleasant. I would expect this plot's axis to begin at 0 for both the x- and y-axis. However, I do not recommend cutting it at the lowest or highest datapoint automatically at all, I think it should be a special case for 0 in the x- and y-axis.
