Before starting... #setup

Make sure you follow the instructions on how to setup a serial connection with the @boardname@.

A typical scenario #example

A common scenario is to chart some sensor data, such as the acceleration, and analyse it in the editor. For example, run this code on your @boardname@.

basic.forever(() => {
   led.plotBarGraph(input.acceleration(Dimension.X), 0);
});

If your serial connection is working, you will start to see a chart representing that acceleration x value read from the @boardname@. Each time led.plotBarGraph is called, the value is also written to the serial output. The log view automatically detects that there is a data stream and displays a graph.
