The chart is the part of the scope view displaying the signals and grid lines. In the X-Y mode, a background image can be placed in the diagram. Furthermore, the chart provides a zoom function. You can draw a zoom rectangle within the diagram, when releasing it, it is zoomed in to the drawn range. When zooming in, the trigger will be disabled. The toolbar buttons can be used to zoom out to the previous level or to zoom out entirely. You can also press the Play button to zoom out and enable the trigger.

If a trigger fires, the chart will be updated with new signal data. The maximum update frequency of the chart is 20 Hz. As the visible part of the memory length gets larger, the update frequency gets smaller. The reduction degree depends on the number of signals, the width of those signals, the base axis mode and its value signal, and the memory length itself.
