I have an array of timestamps in the format (HH:MM:SS.mmmmmm) and another array of floating point numbers, each corresponding to a value in the timestamp array.
Can I plot time on the x axis and the numbers on the y-axis using Matplotlib?
I was trying to, but somehow it was only accepting arrays of floats. How can I get it to plot the time? Do I have to modify the format in any way?
You must first convert your timestamps to Python
datetime objects (use
datetime.strptime). Then use
date2num to convert the dates to matplotlib format.
Plot the dates and values using
dates = matplotlib.dates.date2num(list_of_datetimes) matplotlib.pyplot.plot_date(dates, values)
