No chart data yet.
Print a whole terminal line of the form label:value from your robot and it becomes one data point. Lines with the same label join the same series; anything else prints to the Terminal as usual.
Robot code (PestoLink firmware)
PestoLink.print("voltage:" + String(batteryVolts));
PestoLink.print("rpm:" + String(shooterRpm));
PestoLink.print("heading:" + String(imuDegrees) + "@" + String(millis()));
Terminal lines → chart
voltage:12.61 → point in the “voltage” series
rpm:3450 → new “rpm” series, own color
heading:-87.5@10230 → X = robot time 10230 ms
Motor OK → ignored (terminal only)
@<ms> the X axis uses arrival time — print at any rate you like.
