Axis Scrolling/Zooming Instructions

When scrolling is enabled for one or more axes, as denoted by a slider displayed along the axis, the following user interaction is supported:

  1. If the slider is dragged along the axis, the current min/max values for the axis will be updated accordingly and the chart will be redrawn using those new values when the mouse button is released.

  2. If the mouse is clicked on either side of the slider, in the white area, the slider will "step" in that direction by one tick mark and the chart will be redrawn.

  3. If the mouse is clicked within the slider bar itself while the SHIFT key is held down, then the axis will ZOOM IN by a factor of 2. (i.e., the axis range will be cut in half).

  4. If the mouse is clicked within the slider bar itself while the CONTROL key is held down, then the axis will ZOOM OUT by a factor of 2. (i.e., the axis range will be doubled).

  5. If the mouse is clicked anywhere within the CHART, while holding either the SHIFT or CONTROL key down, then ALL axes will be zoomed accordingly. This allows both the X and Y axes to be halved or doubled at the same time.
