How to adjust X and Y axis scale in Arduino Serial Plotter (no extra software needed)
The Serial Plotter in Arduino is an excellent tool for quickly visualizing serial data. However, it has a limitation that can frustrate many users: it’s not immediately obvious how to adjust the X and Y axis scales, especially the X axis. In a recent article, Boris Landoni shows step by step on how to solve this issue without the need for additional software like Python or Processing.
In the latest version of the Arduino IDE (from version 2 onwards), the X-axis has a moving scale that only shows 50 data points, while the Y-axis is dynamic, adapting to the minimum and maximum values of the last 50 points. This can make data interpretation difficult, especially if you’re monitoring a stable signal such as a sine wave.
