I tried to plot this type of data
x y
00:00 99.42
00:15 99.44
00:30 99.41
00:45 99.37
01:00 99.00
01:15 99.29
01:30 99.51
01:45 99.58
02:00 99.49
02:15 99.50
02:30 99.52
02:45 99.57
03:00 99.56
with pgfplots. But the package cannot read the time data properly.
Is there a way to plot the time format?
