Visualize Data
Use the MATLAB Visualizations app to 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 other MATLAB plots. 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 can Add 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 in Access Add-Ons in MATLAB Analysis and Visualization Apps.
