Thank Daswson & Sterling, Got it, you meant the data should not have date and longitude against each grid point instead should have only 2 vectors rather than grid. 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.

This only applies if your coordinate actually contains datetime objects, if not then coordinates can be 2d as the documentation says. >On 13 Jul 2013 02:22, "Sudheer Joseph" <sud...@ya...> wrote: > >Hi, >> >>I did not understand 1d mentioned by you? for a diagram like this 2D is must as it need longitude /latitude and also time >>with best regards, >>Sudheer >> >>From: Andrew Dawson <da...@at...> >> >>To: Phil Elson <pel...@gm...> >>>Cc: Sudheer Joseph <sud...@ya...>; "mat...@li..." <mat...@li...> >>>Sent: Friday, 12 July 2013 1:28 PM >>>Subject: Re: [Matplotlib-users] Hovemuller Diagram >>> >>> >>> >>>As long as you use contour or contourf and your coordinates are 1d you should be able to do this no problem, just like Phil said.

The installation process is only going to get easier over time, for instance last week we added a PPA so that with the necessary repos added you would be able to "apt-get install python-iris" on an Ubuntu machine - for other installation guides there is a repository of recipes ( https://github.com/SciTools/installation-recipes ). >>>>As for achieving this without iris, it is perfectly feasible. You just need to contourf your data with the longitude as your x coordinate and the date times as your y coordinate. From memory you might also need to tell matplotlib that the y coordinate is date/time (I think that is a mpl bug that ajdawson has recently addressed). Obviously, basemap is not needed as you are not drawing a longitude/latitude plot but a longitude/time or latitude/time one. >>>>HTH, >>>>Phil >>>> >>>> >>>> >>>>On 11 July 2013 19:06, Sudheer Joseph <sud...@ya...> wrote: >>>> >>>>Thank you Signell, >>>>> I was looking for better looking labels as well as a solution with in matplotlib without needing to install additional packages.
