Calculate comparisons between values.

[blaze-developer]

When looking at a log file, for example comparing motor encoders to absolute encoders, it would be useful if we could use the drop-down menu to calculate and plot a comparison between two values like differences, and averages between fields.

I envision this working as follows:

• Users would click on the menu button on the control pane, and select a comparison option such as "view difference" or "view average between", or any other useful calculations.

• A modal would appear prompting the user for the fields they would like to compare. Text would display that says "Show me the difference between ____ and ___."

• The user would then drag fields onto the blank spaces, similar to "upload file" drag and drops on websites.

• After dragging your fields to compare how the you like it, you would press a button to confirm.

• AdvantageScope would then display a line on the 2d graph showing the desired comparison, the name of the field in the control pane as a description of what it is comparing.

I acknowledge that log replay or simply calculating the value within the robot code is more robust and controllable, however it would save lots of time in an analysis to simply be able to calculate these within our data visualization tool.

Along with the time saving capabilities, this would also make more robust analysis possible for students that don't necessarily know how to run a log replay or write code altogether, but would still like to review and analyze log files and data.
