The Chart Control can be moved on the Browser version using the mouse, and the zoom operation can be performed by using the combination SHIFT + Mouse wheel. Zoom for the time scale can be performed with the mouse on the center of the Control or on the time scale. To perform a zoom on the vertical scale, place the mouse over that scale.
On mobile devices with a touch screen, users can perform a zoom by using a two-finger pinch gesture. This gesture can be executed on the scales or on the center of the chart. To move a chart, hold and drag it over a scale.
The Chart Control has Live and Static modes. The Live mode is activated when the local computer or device time is inside the period displayed on the chart. In this mode, the chart moves and displays the last period. The Control's upper left corner shows an indication of this mode.
When changing the visualization period and if the current time is outside the chart area, then the Control leaves the Live mode and enters the Static mode. This mode is useful to analyze details on the chart without a moving Control.
