first is your data file use what column names?
i changed here to
String infilename = "data/samples2.csv";
Time,Intensity
0.000,-0.335
to fit to my code
( or you change the code… )
second the Y auto ranging not work as your data are all negative
** i jumper it here by invert your data by using
iintensity = table.getFloat(i, "Intensity")*(-1); // invert
in 2 different places of the sketch
if you find a better auto ranging adjustment
please post it here
also that is a very big file, cant you start with the first some 100 lines for test,
anyhow now see
