I have attached the csv file of my gcode obtained from the magnetic data from the 3D printer.I want to plot the X_value column against time values.Can someone walk me through this?

Best Answer

data=csvread('1333_mag.csv',1,0);   % read the csv file, skip header row
plot(data(:,1),data(:,2)            % plot 2nd column vs 1st
xlabel('time')
ylabel('X')
Slightly more exotic
data=readtable('1333_mag.csv');  % read again, this time as table object/class...
data.Properties
ans = 
           Description: ''
  VariableDescriptions: {}
         VariableUnits: {}
        DimensionNames: {'Row'  'Variable'}
              UserData: []
              RowNames: {}
         VariableNames: {'time'  'X_value'  'Y_value'  'Z_value'}
plot(data.time,data.X_value)
xlabel(data.Properties.VariableNames(1))
ylabel('X')
Any number of other choices as well...
