Dear all pyplot seems to be plottting(joining points with lines) in the wrong order I have checked all the algorithms relating the data being plotted and everything is in order http://matplotlib.1069221.n5.nabble.com/file/n42696/bad_line_joints.png this can be observed in the image on how it

Hello, Can you provide a short piece of code that shows the issue? Do you provide your points in order and in a collection-like object that preserves the order in which the points are appended? (a Dict or Set would not preserve the ordering). Regards 2014/1/9 Francisco Vargas

As the error message says, the problem is on Line 14: print f.variables['WWSWHGT_P0_L1_GLL0'] a KeyError means that you tried to access an element that is not in a dictionary. In this case f.variables is the dictionary and ' WWSWHGT_P0_L1_GLL0' is the element. Did your data and script come of

Hi Paul, Thanks for your reply, I managed to fix it after I realised the mistake I was making. I've currently got a new problem. If you look at the image below, there's a lot of white showing up around the coasts which ideally I'd like to remove. The map is drawn using basemap, is there a

I believe (as of v1.3.1) that after you create the legend you call leg.draggable(True) http://matplotlib.org/api/legend_api.html#matplotlib.legend.Legend.draggable Outstanding! (Google was not my friend here. I wasn't searching for draggable.) It works if I only plot using the left Y axis.

2014-01-09 Thread Skip Montanaro
On that assumption, I tried changing the legend to be associated with the right Y axis: if a legend is requested: labels = [line.get_label() for line in lines] if I have right axis data to plot: right_plot.legend(lines, labels).draggable(True) else:

I think you posted the same image in both cases. Without seeing the problematic image, I can only guess that it's caused by the resolution of your data. On Thu, Jan 9, 2014 at 7:58 AM, A Short surfersh...@hotmail.com wrote: Hi Paul, Thanks for your reply, I managed to fix it after I realised

Ive also changed the grib file from multi_2.glo_30m.t06z.grib2 to nww3.t12z.grib.grib2 i still cant figure out which is the right file for the North East Atlantic neither...i wonder if my data source is wrong..? http://matplotlib.1069221.n5.nabble.com/file/n42710/figure_2.png -- View this

Looks like it's just a coarse resolution to me. Try showing the data as an image with no iterpolation. On Thu, Jan 9, 2014 at 3:26 PM, A Short surfersh...@hotmail.com wrote: Ive also changed the grib file from multi_2.glo_30m.t06z.grib2 to nww3.t12z.grib.grib2 i still cant figure out which is
