+  * Drag mouse on X or Y axis to zoom that axis only
   * (0.2) Mouse filter, for example allow only left click drag to zoom
   * (0.2) Animated zooming
   * (0.3) Mouse wheel zoom in plot area, X axis, or Y axis. This has NOT been tested with mice with "continuous" wheels, only ones that rotate in discrete steps/clicks.
