## Before starting... #setup
|
|
|
|
Make sure you follow the instructions on [how to setup a serial connection](/device/serial) 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@.
|
|
|
|
```blocks
|
|
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.
