[Feature Request] Ability to receive axis labels from serial data

[nomakewan]

In the Arduino Serial Plotter, it is possible to send the name of a variable alongside the data value. The example for this is here.

In short, the datagram uses CRLF/LF to separate messages and uses comma/tab/space as a delimiter for variables, but the NaN portion preceding the numerical value (ending in a colon) is accepted as the name of the variable in question. So a sample datagram would look like this:

W.AvgPow(W):0.52,W.State:0.49W
or
W.AvgPow(W):0.52 W.State:0.49W
or
W.AvgPow(W):0.52 W.State:0.49W

Then the Serial Plotter displays a key with the variable names received from the datagram, and of course plots the new value received on the line chart.

I have noticed that when this recommended datagram structure is used with SerialAnalyzer, it causes the program to fail to plot any data. Once I modified my sketch to only include numerical values, the plot worked as expected.

Adding the ability to interpret NaN as a label name would be fantastic as it would make this program a drop-in replacement for the Arduino Serial Plotter.

Thank you!

It's a good request. Easy to implement too. I'll look at adding this if I find some time.

Thank you so much for looking into it! I really appreciate it, this has been a great program to use!
