@aidanheerdegen Thanks for the code. I suppose it's better to mention this method for DataArray in User Guide. @dcherian Should I create a PR for example like this?

``` air = xr.tutorial.open_dataset("air_temperature")['air']

air.isel(lon=10, lat=[19, 21, 22]).plot.line(x="time", marker='o',linewidth=0.,markersize=1) ```

In the absence of a dedicated method, it is possible to obtain a scatterplot with the keyword options to plot.line(): rho_so_remap.plot.line(marker='o',linewidth=0.)

I agree this could be helpful... is there any interest in reviving this stale issue?

This certainly could be useful, but since this is essentially plotting a vector of data, why not just drop into pandas?

``` df = da.to_dataframe()

Could reset coordinates if you really wanted

df = df.reset_index()

df.plot.scatter('longitude', 'latitude', c=da.name) ```

Patching in this rough functionality into the plotting module should be really straightforward, maybe @jhamman has some tips?

+1

Especially useful when using unstructured spatial datasets like observation stations.

import xarray as xr nstations = 9 data = np.random.random(size = nstations) longitude = np.random.random(size = nstations) + -90 latitude = np.random.random(size = nstations) + 40 da = xr.DataArray(np.random.random(nstations ), dims = ['station'], coords = dict(longitude = ('station', longitude), latitude = ('station', latitude)) da.scatter(x = 'longitude', y = 'latitude')
