Zooming charts

JetChart implements zooming of certain types of series. Series configured and displayed with the GraphApplet applet support zooming.
To zoom into a region of the area series displayed below, click the left or right mouse button at a point within the chart area and drag cursor. After selecting the area to be zoomed, release mouse button and the selected area is expanded. To return a zoomed chart to normal view, right click mouse button at any point of the chart area.
A scrolling bar to scroll zoomed charts can also be placed at one of the four chart sides.
