The chart doesn't automatically change its zoom in order to fit the plotted data. In order to achieve this you can set up the chart's zoom manually via the the following properties:
The properties work in relative units between 0 and 1.
By default the chart pan and zoom behavior enables only zooming interactions on the horizontal axis. To enable them also for the vertical axis you can set the ZoomMode property of the behavior to Both. You can read more about the pan and zoom behavior
in the chart's documentation.
