Dear Paul, The issue I am facing is like in the attached plot where the month naming get cluttered. with best regards, Sudheer *************************************************************** Sudheer Joseph Indian National Centre for Ocean Information Services Ministry of Earth Sciences, Govt. of India POST BOX NO: 21, IDA Jeedeemetla P.O.

I used ferret to do this based on the length of the time axis it chose the mode of labelling. for example in case of 2 year plot it made month labeling as j f m etc and in case of 1 year as there is enough space on x axis it made jan feb etc with single label of year. > >In the attached python plot (ATser_RAMA_HYCOM_U_8n90e.png) every tick point is lablled for year, which I wanted to avoid and get plots similar to the first types thought it is not done automatically but at least manually. > > > > > >*************************************************************** >Sudheer Joseph >Indian National Centre for Ocean Information Services >Ministry of Earth Sciences, Govt. of India >POST BOX NO: 21, IDA Jeedeemetla P.O. >Via Pragathi Nagar,Kukatpally, Hyderabad; Pin:5000 55 >Tel:+91-40-23886047(O),Fax:+91-40-23895011(O), >Tel:+91-40-23044600(R),Tel:+91-40-9440832534(Mobile) >E-mail:sjo...@gm...;sud...@ya... >Web- http://oppamthadathil.tripod.com >*************************************************************** > > >>________________________________ >> From: Paul Hobson <pmh...@gm...> >>To: Sudheer Joseph <sud...@ya...> >>Cc: "mat...@li..." <mat...@li...> >>Sent: Friday, 7 June 2013 8:50 PM >>Subject: Re: [Matplotlib-users] time axis format >> >> >> >> >> >> >> >> >>On Thu, Jun 6, 2013 at 11:39 PM, Sudheer Joseph <sud...@ya...> wrote: >> >>Dear Experts, >>> I have been experimenting with the plot_dates option of matplotlib to plot time series data and have below questions >>> >>> I have used >>>loc = mdates.AutoDateLocator() >>>ax.xaxis.set_major_locator(loc) >>>ax.xaxis.set_major_formatter(mpl.dates.DateFormatter('%b\n %Y')) >>> >>> >>>and got the tick labels in attached plot >>> >>>However I feel the repeatd year labeling is not needed here and it is required once in a year only , Also if I need to plot long time seris insted of "MAR" "APR" I wanted to get them reduced to "M" "A" etc so that the lavel congestion can be avoided. >>> >>> >>>I notice that below options are available, but was wondering how commbinatins of these locateors are used ie mark every month and every year once each. >>> >>> >>>Is there a way to achive the above or does it need further development? >>> >>>fmt = mdates.DateFormatter('%Y-%m-%d') >>>loc = mdates.WeekdayLocator(byweekday=mdates.MONDAY,interval=4) >>>locator = mdates.YearLocator() >>> >> >> >>If I were trying to do this, I'd cobble something together using by the minor and major formatters. >>e.g.,... >>import matplotlib.dates as mdates >>import matplotlib.pyplot as plt >> >> >>fig, ax = plt.subplots() >> >> >>majorLocs = mdates.MonthLocator(bymonth[1,7]) >>majorFmt = mdates.DateFormatter('%b\n%Y') >> >> >> >>minorLocs = mdates.MonthLocator(bymonth[1,7]) >>minorFmt = mdates.DateFormatter('%b') >> >> >> >>ax.xaxis.set_major_locator(majorLocs) >>ax.xaxis.set_major_formatter(majorFmt) >> >> >> >>ax.xaxis.set_minor_locator(minorLocs) >>ax.xaxis.set_minor_formatter(minorFmt) >> >> > > |
