Meteoinfolab Script Example: Multi-y-axis diagram

Multiple Y-axes are important when comparing data ranges that are relatively large. A Twinx function is provided in Meteoinfolab to generate a new Axes based on the existing coordinate system (Axes), which causes the existing Axes not to draw the right y-axis, and the newly generated Axes draws only the right y-axis. The YAxis function can set the y-axis of a axes, the first parameter is a axes object, you can set the y-axis color and offset (shift), and the 3rd y-axis must be offset to avoid the gland for graphs over 2 y-axes.
