New chart for "digital" graphs

The new Easy Charts in version 2.0 or later feature a “digital mode” on a per pen basis. Besides using the digital renderer, it will “space” the data out if you have many overlapping values. Suppose you have 6 pens that only have values of 0 or 1 (on or off), you will be able to read all of the values due to spacing.

We’re still looking for the best way (pen or axis level) of defining a mapping for those digital values. This will actually show “Running” or “Faulted”, for example, instead of 1 or 0.
