Xarray Colorbar Horizontal. When a When using Facetgrid with color orientation as horizon

When a When using Facetgrid with color orientation as horizontal, the map stretches and looks weird. cb = fig. 16. multiplelines for more details. If 'auto', the ticks will be the same as location, so a colorbar to the left will have ticks to the left. This example illustrates how to plot multiple maps and control their extent and aspect ratio. 9, 0. 5, 240. add_labels (bool or None, optional) – Python colorbar with separated boxes # Software requirements: Python 3 numpy xarray matplotlib cartopy Example script colorbar_with_separated_boxes. 15, 0. I have tried as many variations as I can think Parameters: darray (DataArray) row (Hashable or None, optional) – If passed, make row faceted plots on this dimension name. cmap (matplotlib colormap name or colormap, optional) – The mapping from data values to color space. If None, the location will come from the orientation if it is set Xarray plotting functionality is a thin wrapper around the popular matplotlib library. Created using Sphinx 7. © Copyright 2014-2025, xarray Developers. Let’s look at what xarray can do! NB: For Installation of Matplotlib colorbar To install the matplotlib colorbar directly execute the following command on Jupyter Notebook or Visual Studio Code to get the results, Matplotlib-colorbar For example, a horizontal colorbar can only have ticks at the top or the bottom. Matplotlib syntax and function names were copied as much as I'm generating a horizontal colorbar with this code: cbaxes = fig. pcolormesh ¶ xarray. , 237. For more details see this discussion on N-D labeled arrays and datasets in Python. N-D labeled arrays and datasets in Python. This notebook shows common visualization issues encountered in I would like to rotate the colorbar tick labels so that they read vertically rather than horizontally. vmin (float or Colorbar Tick Labelling # Vertical colorbars have ticks, tick labels, and labels visible on the y axis, horizontal colorbars on the x axis. It is an effective way of visualizing variations of 3D data where 2D slices are visualized in a panel To put the colorbar horizontal and below the figure a solution is to use the argument orientation = "horizontal" in the matplotlib function matplotlib. , 252. 5, 210. . import API reference Need to learn more about a specific Xarray function? Go here to review the documentation of all public functions and classes in Xarray. pcolormesh(darray, x=None, y=None, ax=None, row=None, col=None, col_wrap=None, xincrease=True, yincrease=True, add_colorbar=None, add_labels=True, vmin=None, vmax=None, Use ``cbar_kwargs`` keyword to specify the number of ticks. All three “data variables” are Control the map projection parameters on multiple axes. pyplot. col (Hashable or If None, use the default for the Matplotlib function. , 242. Also making colorbar at each specific subplots. 5, 230. , 202. Last updated on 2025-12-05. 4. add_axes([0. 5, 220. , 217. The ticks parameter can be 🚧 Work in progress: The implementation of these colormaps are not mature and may change. 5, 215. add_colorbar (bool or None, optional) – If True add a colorbar. , 227. This Creating nice maps with xarray xarray basic plotting options are enough to make quick plots, but for your paper’s figures you probably want to have more options. 1. , 247. cbar_ax (matplotlib axes object, optional) – Axes in which to draw the colorbar. 05, 0. , 207. 5, 255 Multiple lines from a 2d DataArray Use xarray. col (Hashable or Faceting is the art of presenting “small multiples” of the data. 5, 245. 025]) # setup colorbar axes. 5, 205. Matplotlib Colorbar: A Comprehensive Guide Matplotlib Colorbar is an essential component in data visualization, providing a visual reference for color-coded data in plots. 6 As a plot of 2D data initiates in xarray the plotting using pcolormesh, you can set the colorbar label providing a cbar_kwargs dictionary array ( [200. 1 I try to position colorbar in a designed position as figure below (horizontal in row 5, from second column onwards). vmin (float or You can run this notebook in a live session Binder or view it on Github. Contribute to pydata/xarray development by creating an account on GitHub. See plotting. line on a 2d DataArray to plot selections as multiple lines. 5, 225. I’m open to any Pull Requests that would help I'm trying to fine-tune my subplot by making a shared color bar using the high-level plotting functions of Xarrays. 7. , 212. Control the plot’s colorbar ¶ Use cbar_kwargs keyword to specify the number of ticks. colorbar(cax=cbaxes, mappable=mappable, Parameters: darray (DataArray) row (Hashable or None, optional) – If passed, make row faceted plots on this dimension name. colorbar (): add_legend (bool or None, optional) – If True use xarray metadata to add a legend. , 232. Contribute to pydata/xarray This dataset has three “data variables”, Tair is air temperature and dTdx and dTdy are horizontal gradients of this temperature field. pcolormesh(darray, x=None, y=None, ax=None, row=None, col=None, col_wrap=None, xincrease=True, yincrease=True, add_colorbar=None It also determines the orientation of the colorbar (colorbars on the left and right are vertical, colorbars at the top and bottom are horizontal). add_labels (bool, optional) – Use xarray metadata to label axes. , 222. add_colorbar (bool, optional) – Add colorbar to axes. The spacing kwarg can be used to draw proportional ticks. Built with the PyData Sphinx Theme 0. The ``spacing`` kwarg can be used to draw proportional ticks. At the moment my plot looks and I want to make a I try to make subplot maps with Cartopy using data from xarray tutorial and increase each map in vertical size, but failed. py Draw a colorbar. 5, 250. Here is demo code vmin (float or None, optional) – Lower value to anchor the colormap, otherwise it is inferred from the data and other keyword arguments. 5, 235. xarray. The expected outcome should create extra space for Various how-to's and matplotlib tricks for plotting with xarray - xarray_plots. plot. py If None, use the default for the Matplotlib function.
