Charts
A chart is a graphical representation of the device data as it changes over time. The x-axis in a chart is
always time. A chart may display one or more trends which are collectively called as a Source. Further, a
chart may have more than one source which you may select to view. The colors, labels, and axes of
charts may vary from device to device as defined in the DD file. The rate at which the chart is refreshed
is governed by the DD file. The default refresh rate is 3 seconds.
The following are the types of charts.
Strip: In a Strip chart data scrolls from right to left. New data is updated at the right end of the chart
with the historical data shifted to the left. Older historical data scrolls off to the left end of the chart.
