Pleae see my chart. It has large numbers, and the change over the time period is small compared to the absolute numbers. The gain of one grid is not well visible by having a look at the axes and will be completely gone when the numbers continue to grow.
How to resolve this common problem? E.g. display only the delta values and show the difference somhere else.
2nd question: I have two lines of data on different axes. I want to have only one fit into the screen, the smaller shall begin at y low point and the meaning of one grid shall be the same so that both values are better comparable.
