+ You can define a custom range for the Y axis. Since there are two Y axis, you can define both of them. You can also
+ only define the min or max values. Since one of the Y axis is slaved to the other one (the right one is slaved to the left one),
+ you cannot absolutely define the range of the slaved axis because it has to use the same lines. The values you supply are used as guidelines however.
+ If the zero-lines have to be aligned, you can use the option alignZeros. It is enabled by default.
