Zooming

When a chart is selectable, you can zoom to an area of the chart by placing the cursor within the chart area and clicking an area, or enclosing an area in a rectangle selector. When the cursor is in the chart area, it becomes a magnifying glass. You can zoom to the horizontal, vertical, or both axes in the chart to view specific data. To zoom out on the chart, right-click the mouse while the cursor is in the chart area.

Depending on the options you enabled, the chart is restored to its original magnification or to the magnification set by the HiLimit and LoLimit properties (on the Y-axis) and the Start Time and End Time properties (on the X-axis). The following table summarizes the options to set or clear to achieve the effect you want.
