Hi Joshua,
As you can see from the attached graph, there is a break the in graph somewhere around 7 AM or so. This is the data I am graphing for that red line:"2007-10-09 00:00:00",0.015 "2007-10-09 01:00:00",0.015 "2007-10-09 02:00:00",0.014 "2007-10-09 03:00:00",0.012 "2007-10-09 04:00:00",0.008 "2007-10-09 05:00:00",0.002 "2007-10-09 06:00:00",-0.006
<snip>
If I change the -0.006 at 6:00AM to 0.006, it graphs with no break in the line.
Can not comment on Matplotlib, ... but what method are you using the process your input? RegEx or other ?, can it handle negative input? The attached script has missing data points where the data point in None Don't know if that helps Steve
from matplotlib import pylab , numerix X1= [ 0.3, 1.2 , -4.3 , 2.5, 2.5, -1.5, 1.2, .8 , 3.5 ] X2= [ 0.3, 1.2 , None , 2.5, 2.5, -1.5, None, .8 ,3.5 ] ax1 = pylab.subplot(2,1,1) pylab.plot(X1, marker='o') ax1.set_ylim(-5,3) ax2 = pylab.subplot(2,1,2) pylab.plot(X2, marker='o') ax2.set_ylim(-5,3) print type(X1[0]) print type(X2[0]) pylab.show()
