Hello Ray,
There appears to be something wrong
with the way “val” is used in the first code section (if val==0:
val = 0 ?), unless it is modified externally somehow?
I would also suggest adding random values
or some such to make the test data non-periodic, so that it doesn’t always
look the same.
Best regards,
Brett McSweeney

[Matplotlib-users] continuous plotting…
Hello
I am trying to use this application to plot a diagram from a log file that
is always active and storing data. I have written the following and I have
issues once I touch the figure window it freezes…
from pylab import *
import time
val = 1
while True:
inData = load('c:\\data.txt')
x = inData[:,0]
y = inData[:,1]
plot(x,y,'o')
if val == 1:
show()
time.sleep(1)
if val == 0:
val = 0
time.sleep(1)
draw()
I am using the following program to create some dummy data:
import time
import math
def test():
for i in range(900):
for rad in sineVal:
fileData = open('c:\\data.txt','a')
time.sleep(1)
fileData.write('%d' % int(i))
fileData.write('\t')
fileData.write('%f' % math.sin(rad))
fileData.write('\n')
fileData.close()
print('*'),
def makeArray():
tempArray = []
for i in range(0,360,180):
tempArray.append(i)
return tempArray
sineVal = makeArray()
test()
You help and suggestion in the above matter will be most welcomed.
