问题 I'm trying plot two panels in a plot. The first one (left) is a data with latitude values in its y-axis. The second panel is a map. I wanna that the latitude values of both panels coinciding, but I don't know how get it. I have a code like this: fig_mapa= plt.figure() '''Mapa''' ax1=fig_mapa.add_subplot(122) map = Basemap(llcrnrlon=-90,llcrnrlat=-58.1,urcrnrlon=-32,urcrnrlat=12.6, resolution='f',projection='merc',lon_0=-58,lat_0=-25, ax=ax1) map.drawparallels(np.arange(-90,90.,5), labels=[0,1

问题 I tried to install basemap within Datalab using pip: %bash pip install basemap and got the error: Downloading/unpacking basemap Could not find any downloads that satisfy the requirement basemap Cleaning up... No distributions at all found for basemap Storing debug log for failure in /root/.pip/pip.log How do I install extra packages on Datalab if they are not supported by pip? 回答1: Use apt-get install. In a cell of your notebook: %bash apt-get -y update apt-get -y install python-mpltoolkits

问题 I am trying to plot a scattered heat map on a defined geo location. I can very well plot a normal scattered map with no background but I want to combine it with a given lat and lon. I get the following empty map . Input Input: col[2] and col[3] are the x and y co ordinates & Geo Location Lat: 19.997453 , Lon: 73.789802 000000000023 61.0 19.006113 73.009168 000000000054 65.0 19.009249 73.000342 000000000003 19.0 19.001051 73.000080 000000000012 20.0 19.009390 73.008638 000000000061 82.0 19

问题 I am using a Matplotlib plot (with Basemap) inside of a wxPython pane. I have got the plot (US map with scatter plot of cities). I am trying to do some interactive zoom capabilities (select a box on the map and "zoom" into that area only). I have managed to get the toolbar to show, but when i click on the buttons, nothing happens. Seems like the toolbar is just there for show. Any Thoughts? Here is my code: # Set up area for plotting Basemap Plot and scatter plot self.figure = Figure(None,dpi

问题 I am creating a series of lat/long scatterplots on a map from basemap. I am planning on creating thousands of plot, with different lat/long data. To save time I wanted to draw the map overlay only once: map = Basemap(epsg=3395, projection='merc', lat_0=59.45, lon_0=10.5, resolution = 'h', llcrnrlon=minlong, llcrnrlat=minlat, urcrnrlon=maxlong, urcrnrlat=maxlat map.arcgisimage(service='ESRI_Imagery_World_2D', xpixels=3000, verbose=True) However, I find no way of clearing my previous

问题 I would like to know how I can generate the marker for the black colored line shown in this picture. (Source: NCEP & NOAA) It's the marker for a storm or hurricane in standard weather maps. I can probably generate an image file of the marker symbol. But, I am not aware of how I can tell matplotlib to use the image as a marker. 回答1: The marker looks like a 6 . If this is the case, you can use a 6 as a marker as follows: import matplotlib.pyplot as plt x = [1,2,3,4] y = [2,3,1,4] plt.scatter(x

问题 I have figured out a method to cluster disperse point data into structured 2-d array(like rasterize function ). And I hope there are some better ways to achieve that target. My work 1.

问题 When I plot the pcolormesh plot use the colormap from matplotlib.cm (like "jet" , "Set2" , etc), I can use: cMap = plt.cm.get_cmap("jet",lut=6) The colorbar shows like this: But if I want to call the colormap from the Basemap package (like GMT_drywet , GMT_no_green , etc). I can't use plt.cm,get_cmap to get these colormap and divide them. Does mpl_toolkits.basemap.cm have a similiar function like lut ? 回答1: As long as the plot you are making has discrete color values (e.g. contour or contourf
