Hi, I have a plot and the xaxis shows number of seconds after a start point. I would like to convert them to days anyone know how to do this. I have looked at the documentation but cant find what I need.
Couldn’t you divide your data points by the conversion (86400) before plotting? E.g., 432,000 seconds then becomes 5 days.

Another way to do this is to change the Formatter which generates
what the labels of each tick out to be to do this computation.
Take a look at this example:
http://matplotlib.sourceforge.net/examples/api/date_index_formatter.html
Just define something like:
def your_function(x,pos=None):
return "%d days" % (x/86400)
ax.xaxis.set_major_formatter(ticker.FuncFormatter(your_function))
best,
