Using Processing to display data graphs

[richard]

interesting hobby , would like to see real data

just for comparison I did this with python, python allows you to zoom in/out on any portion of the graph and save it a png,pdf or whatever too
for just a dozen lines of code

import csv, sys
import matplotlib.pyplot as plt
filename = 'candaroad.csv'
t=[]   #time
a=[]   #altitude
with open(filename, 'rb') as f:
    reader = csv.reader(f)
    for row in reader:
            #print row
            a.append(float(row[4]))
            t.append(float(row[1]))
plt.plot(t,a,'b-',label='altitude')
plt.show()
#print a

graph looks a bit different to yours , I may have misinterpreted the data

O:,359.54,-16.05,5.61,577.59
O:,359.72,-15.96,5.55,577.02
O:,359.82,-15.97,5.59,576.49
O:,0.00,-15.96,5.55,576.06
O:,0.14,-16.01,5.50,575.67
O:,0.25,-15.96,5.53,575.77
O:,0.40,-15.97,5.48,575.86

I assumed the 577.xx is height and 359.xx is time but the time figure seems to rollover at 360 so I must have guessed wrong
