Analyzing Data

Important

WPILib standarizes on SI units, so its recommended that the Units option is set to Meters.

Once we have data from an identification routine, we can analyze it using the Analyzer and Diagnostic Plots widgets.

Loading your Data File

Now it’s time to load the data file we saved from the logger tool. Click on Select.

In the resulting file dialog, select the JSON file you want to analyze. If the file appears to be malformed, an error will be shown.

Running Feedforward Analysis

Click the dropdown arrow on the Feedforward Section.

Note

If you would like to change units, you will have to press the Override Units button and fill out the information on the popup.

The computed mechanism system parameters will then be displayed.
