I have, e.g. a chart of voltages measured during the day, so I decided to make the minimum Y axis the lowest voltage, and the maximum the highest voltage. So I get hundreds (sampled per minute) of 240V, and one or two 0V. This means the whole graph is at the very top, all compresses, with a vast mass of emptiness underneath except for one or two zero points.
It looks much better when I remove the zero samples. Maybe a logarithmic Y axis, very tight at the bottom, so zeroes have little effect? I don't know. Hardly ever done anything except a very small line graph with much less diverse data samples.
