Visualize Data

Transform and visualize data in MATLAB^®

Use theMATLAB Visualizations appto visualize data in a ThingSpeak™ channel. You can view and explore data using interactive visualizations such as an area plot, line plot, or scatter plot in static visualizations using otherMATLABplots. You can also make visualizations public and use the URL to embed them on websites. ThingSpeak also allows you to use MATLAB to analyze your data. The MATLAB Analysis and MATLAB Visualizations apps provide code templates to assist you with basic operations on your historic or live data. Use code template tutorials to get started with ThingSpeak. Use the apps to convert from one unit to another, compare different or similar data on the same plot, or visualize the statistical distribution of your data.

You canAdd Functions to Scripts(MATLAB)in MATLAB Analysis and Visualization apps to allow for modular coding. In addition to the built-in MATLAB functions, you can also use functions from the toolboxes mentioned inAccess MATLAB Add-On Toolboxes.

Featured Examples

Create Heatmap Overlay Image

Create a heatmap using wireless network signal strength measurements from an ESP32 development board. ThingSpeak™ helps you visualize your data by projecting measurements over an image or map. You do not need special hardware, but you need an image of the area and position measurements. For more information, see Wireless Network Signal Strength with ESP32 in Arduino.
