5.3.4 Graph Tab

The Graph tab contains a plot window that shows the progression of data over time on the INA230. All four variables at the bottom of the EVM software (VBUS, VSHUNT, Current, and Power) can be plotted using the drop-down box directly above the graph. After the desired plot has been selected, toggle the Continuously Poll Data button above the plot to begin polling for data. If the user desires to save the data from the plot, simply select the USB Controls drop-down at the top of the page, then select the Start Graph Log option. When the Start Graph Log is selected, the user is prompted to select a location for the data and to name the file.
