How to draw three y axis using the gnuplot at the same x axis in one graph?

As mentioned in my title, I need to draw more than two y axis for the same x-axis of some specific scale. Can someon开发者_如何学编程e can tell me how to do this?

In gnuplot only two differently scaled y-axis are possible.
But you could either

• scale your data against a certain value to plot relative values instead of absolute values,
• or simply have multiple plots. (multiplot)
