how to use time formatting in wxmpl (NOT FOR MATPLOTLIB)

Question

I have a time list below for plotting:

time_list = [63158,63159,63200,63201,63202]

But i want like this in graphic:

time_list = [6:31:58,6:31:59,6:32:00,6:32:01,6:32:02]

And between 63159 and 63200, shouldn't be behave as if there is 40 numbers among them.

I can use this with matplotlib library, but for my purpose wxmpl is better than it.

So my question is how can i use time formatting with any plot library except matplotlib?

Answer 1

Currently, wxmplot.PlotPanel.plot() (and .oplot()) supports auto-converting of xdata into date-time values only when using plot(xdata, ydata, use_dates=True) and only with xdata as Unix timestamps.

That is, use_dates=True does

from datetime import datetime
from matplotlib import dates

...
def plot(xdata, ydata, ..., use_dates=False, ....):  
   ...
   if use_dates: 
       xdata = dates.date2num([datetime.fromtimestamp(i) for i in xdata])

So, I think you will have to convert your custom encoding of time data into a more standard representation of times. I think you have two options:

1. convert your time_list data into timestamps (seconds since epoch) and use use_dates=True.

2. convert your time_list data into an instance of matplotlib.dates, possibly using datetime as an intermediate form and use use_dates=False.
