Serial Plotter examples

[pierrotm777]

I see a new 'Serial Plotter' feature that arrive with the future IDE 1.6.6 .

Can you give us some examples for it use ?

Thanks

There is an example sketch at #2177 (comment)
It would be nice if you could provide an example good enough to be included in the standard set

[pierrotm777]

It's fantastic new feature .
I cool option would be to add several plots possibility in same time with different colours :-)

/cc @henningpohl in case he wants to jump in

I added a basic example here: henningpohl/Arduino@0f395d8

It is a bit odd though, as the example is not really showing off capabilities of the Arduino, but instead of the IDE. Would you want a PR for this anyway?

As for extension options: certainly multiple graphs, each with a different color, would be a clear way for this to move. There's a bit of a trade-off in that this could get overly complicated if not kept in check. For example, somebody might want to add spectrograms, logic analysis, or signal smoothing. I personally don't think that's what this should become. But hey, at the end that's really up to the people using this.

Thank you @henningpohl, we are reviewing it

@henningpohl instead of a new example, we prefer enriching AnalogReadSerial description. See d9b3a86

[ffissore]

And ReadAnalogVoltage. See 974fef1

Maybe it should be noticed in these comments that Serial Plotter only works with Serial.println() -because it uses \n as value delimiter, does it?- but not with Serial.print() or Serial.write().

@henningpohl The idea of showing multiple graphs...is finally discarded?

[henningpohl]

@q2dg not discarded, but I won't have time for this before mid-October

Ok, thanks a lot. Casually yesterday I wrote a comment in #2177 asking for the same...I don't wanna be onerous, sorry

[q2dg]

@henningpohl Thanks a lot for that pull request!! Let's see if we are lucky and it gets merged...
If it were...how would be a code sending two series of values? Is there some identifier inside the message written by Serial.println()?? Thanks!!

[henningpohl]

You just need to separate individual values by commas or spaces. So you could, e.g., send one update from the Arduino as: "3.4, 5.4, 1.0\n".

Ahhh, terrific!! Thanks!

Here's a link to a tutorial that I made on Instructables about the Arduino Serial Plotter. It has a detailed explanation & example code too.
