QUESTION
I'm trying to plot some big cities of Spain and tag them with their names, according to Natural Earth data. If I only plot the points, using ax.scatter, I get my figure correctly, without points outside it. But when doing ax.text in the same way, I get all the names of cities of the world outside the picture...
The code is here:

QUESTION
I am working with the NDFD forecast datasets and would like to assign lat and long within the array to give me the ability to plot the data outside of matplotlib. My versions are:
python 3.8,metpy 1.0.0,cartopy 0.18.0, xarray 0.16.2, siphon 0.8.0

requires that information about the CRS is available, so that it can properly calculation longitude and latitude from your projected coordinates. This means that you first need to have called parse_cf()
in some way. In your code above, you save the results of calling parse_cf('Total_precipitation_surface_6_Hour_Accumulation')
to var
, but this does not modify the original Dataset
stored in ds
.
Instead you need to either call it on the variable that has had the information parsed as:

I have a plotted map with station locations (from a CSV) but I am finding it difficult to add text to the points using their station name referred to as "STATIONS" in the first column of the CSV file attached. Below is the code compiled so far. Thanks.

QUESTION
I have successfully created a map (country boundary and coastline) from natural earth site but I am finding it difficult to plot the longitude and latitude coordinates of weather some stations to the map. The longitude and latitude coordinates are the CSV file attached.
Below the is code compiled so far and the map generated:
...ANSWER
Answered 2020-Dec-19 at 14:44This requires two steps
Read in the csv data to Python. You can do this with numpy or pandas, e.g.
weather_stations = pd.read_csv('path_to_file.csv')
Use the matplotlib function scatter on your geoaxes
ax_map
. You need to tell the geoaxes the coordinate reference system of your input data. It looks like lons and lats, this is the Plate Carree coordinate reference system. You pass this with the kwargtransform
Taking the data we imported in step 1:
ax_map.scatter(weather_stations['LONG'], weather_stations['LAT'], transform=ccrs.PlateCarree())

I have a figure with 3 subplots, two of which share a colorbar and the third has has it's own colorbar.
I would like the colorbars to align with the vertical limits of their respective plots, and for the top two plots to have the same vertical limits.
Googling, I have found ways to do this with a single plot, but am stuck trying to make it work for my fig. My figure currently looks like this:

Answered 2020-Nov-25 at 11:04I don't have any insight for generators, but I answered a related question about colouring a nation on a map from a list of nation names and values https://stackoverflow.com/a/61525984/13208790
The key step is reading the natural earth data into geopandas, so you have a dataframe rather than a generator to work with. Not very elegant but should work:

I am using the following code to make a map for Sweden, Norway and Finland together as one area. however, I am struggling with it. I'm following this example, Python Mapping in Matplotlib Cartopy Color One Country.
...ANSWER
Answered 2020-Nov-21 at 10:45The code here that you adapted to your work is good for a single country. If multiple contiguous countries are new target, one need to select all of them and dissolve into a single geometry. Only a few lines of code need to be modified.
Example: new target countries: ['Norway','Sweden', 'Finland']

Install ShapeReader
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
