Fix Serial Plotter sketches for compatibility with all IDE versions #621
Conversation
The sketches provided in the Arduino IDE 2.x Serial Plotter documentation used variable labels that contained spaces. Support for spaces in labels has been intentionally dropped in order to enable fixes for critical bugs in Serial Plotter that made it incompatible with the data formats established for years by the Arduino IDE 1.x Serial Plotter. Since that Serial Plotter never supported spaces in labels, and thus the existing body of sketches did not use them in labels, it was determined an acceptable tradeoff. It may be that this enhancement will be implemented at some point in the future, but for now the example sketches in the docs must use the currently supported data format.

What is the issue on printing a string with spaces? |

@marqdevx this is what the previous sketch looks like in the plotter:
Note that the variable labels are "1" and "2" instead of "Variable 1" and "Variable 2". Here is how sketch looks in the plotter after my proposed change:
Note that the variable labels are "Variable_1" and "Variable_2", just as they are in the code. |

I didn't know about this!! 🤯 It would be nice to also update the screenshots of the Serial Monitor @jacobhylen |
Thanks for raising that point @marqdevx. I agree. I apologize for not taking care of that as part of the PR. Although screenshots are easy enough for me, I'd be happy to submit a separate PR providing those if you like. |

What This PR Changes
Use the supported variable label format in the Serial Plotter demonstration sketches.
