Jan 07, 2016 The Serial Plotter. Arduino’s serial plotter is really easy to use. Instead of just showing a bunch of numbers and/or characters like the serial monitor does, the serial plotter actually draws the numbers over time, where the y-axis is the value and the x-axis is the time.
- Using the Arduino Serial Plotter. By Brent Rubell. We're going to start plotting.values! Arduino comes with a cool tool called the Serial Plotter. It can give you visualizations of variables in real-time. This is super useful for visualizing data, troubleshooting your code, and visualizing your variables as waveforms.
- The serial plotter can be invoked after uploading code to the Arduino board, by clicking on tools - serial plotter from the drop-down menu or by pressing CTRL + SHIFT + L which is the keyboard shortcut for the same. Launch the Serial Plotter. To demonstrate the use of serial plotter in.
- Nov 12, 2015 This means that the plot is updated every time you use the Serial. Println command with a new value. Download the Arduino IDE version 1.6.6 or above. In order to use the Serial Plotter tool you need to download the latest version of the Arduino IDE, at the time I’m writing this blog post is version 1.6.6. Arduino with DHT11 Temperature and Humidity Sensor.
- The Arduino Serial Plotter takes incoming serial data values over the USB connection and is able to graph the data along the X/Y axis, beyond just seeing numbers being spit out on to the Serial Monitor. The vertical Y-axis auto adjusts itself as the value of the output increases or decreases, and the X-axis is a fixed 500 point axis with each.
Now that you have installed the latest version of the Arduino IDE(1.6.7 or above) its time to understand how the Serial Plotter actually works. The Arduino Serial Plotter takes incoming serial data values over the USB connection and is able to graph the data along the X/Y axis, beyond just seeing numbers being spit out on to the Serial Monitor. The vertical Y-axis auto adjusts itself as the value of the output increases or decreases, and the X-axis is a fixed 500 point axis with each tick of the axis equal to an executed Serial.println() command. In other words the plot is updated along the X-axis every time the Serial.println() is updated with a new value.

Remember to set the Baud Rate of the Serial Plotter so that it matches that of the code.
Multiple Plots
When displaying multiple waveforms, every separate variable/value/parameter is displayed using a different colour like shown below.
Inorder to plot multiple variables or waveforms simultaneously a 'space' is printed between the two print statements.

OR
Arduino Plotter Tutorial
In this case the values of the variables 'temperature & humidity will have separate waveforms plotted on the same graph simultaneously.
