Add the option to enable/disable chart data points

[TheRustyPickle]

The chart renders all the tx method data at once. Perhaps another row can be added with all the tx method names where they can be enabled or disabled on perhaps Space or Enter press.

• Add a new row that will show all tx method
• The new row will be selectable/cyclable similar to how the other rows are
• Default all methods will be selected
• Selected methods should have a different color
• Will become hidden on double 'r' press as it happens on the chart page right now
• Selected methods should be saved in a vector(?) or something similar and passed to the chart UI where it will render based on that. Should ignore all data points if not selected
