Configuring the Chart

When first opening the Drive page the chart options menu will open automatically. Chart options are saved between configurator sessions and your previous configuration will automatically be applied unless you have reset the chart.

The chart options menu displays subchart configurations on the left and plottable parameters for each node that is sending telemetry on the right.
