RSTchartModes constants

Only used when the DataServer property is sent to None. In Manual mode, the container that holds the trend object sends data to the chart using the NewData method. The container manages the chart timing and sends the trend object an array with new data for each point at the intervals specified in the NewData method.

In Automatic mode, the RefreshRate property controls how often the chart acquires data. rstAutomatic can be used with a data server or the pen value property.

In On Change mode, real-time data updates in the chart immediately, as the values change. To avoid missing data between updates, you may want to select the On Change mode when working with data that changes rapidly. RstOnChange can be used with a data server or the pen value property.
