graph arduino IDE

HI

Is there a way to customise the graph u get from"serial plotter" by adding label axis and also to split the printing to to have two different graphs on the same plotter

One of many Google hits for Arduino serial plotter

No there isn't. You could output the data as comma separated text to the Serial Monitor, copy the data, and then paste it into a spreadsheet and then have the ability to generate much nicer graphs using the features of the spreadsheet application but this doesn't allow real time graphing.
