How can i make an empty graph without using csv?

[jafal]

Hi

Some informations here

Use Processing to make continuous graph using CSV

a GRAPH / PLOT as a short window of data from ONE CSV file? or a graph of all data from CSV with a zoom function? possibly better use a library ( loaded via PDE contribution manager ) like https://jagracar.com/grafica.php still i think you should start with your own little plot function -1- point(x,y) -2- rect() -3- a line connecting the measuring points and ignore the axis / grid beauty things at first next need check data in a first loop for min max to auto adjust graph float dmi…
