Tabbed plots with linked (shared) data ranges
4
Shows how to place plots in separate tabs. Also shows how two plots can
5
dynamically display the same range of data, so that a zoom or pan in one
6
plot will automatically be shown in the other.
8
In this example, the top panel plots a sin function. The bottom panel contains
9
two tabs, plotting a tan function and a mixed trig function respectively.
11
The three plots are linked. The sin and mixed plots share both x- and y-axis
12
data ranges. The tan plot shares only its x-axis with the other two.
14
Mousewheel zooms in or out. Left-mouse-drag pans.
15
Typing "z", then left-mouse-drag, zooms to a specified region.
17
If you zoom or pan one plot, you will see changes in one or both axis ranges
