Is it something other than what one would do with a LineCollection, e.g., In particular, do not # add the colorbar using the figure's method, # telling which mappable we're talking about and, # repeat everything above for the negative data, # you can specify location, anchor and shrink the colorbar, # Plot both positive and negative values between +/- 1.2, # Add minorticks on the colorbar to make it easy to read the, Discrete distribution as horizontal bar chart, Mapping marker properties to multivariate data, Shade regions defined by a logical mask using fill_between, Creating a timeline with lines, dates, and text, Contouring the solution space of optimizations, Blend transparency with color in 2D images, Programmatically controlling subplot adjustment, Controlling view limits using margins and sticky_edges, Figure labels: suptitle, supxlabel, supylabel, Combining two subplots using subplots and GridSpec, Using Gridspec to make multi-column/row subplot layouts, Complex and semantic figure composition (subplot_mosaic), Plot a confidence ellipse of a two-dimensional dataset, Including upper and lower limits in error bars, Creating boxes from error bars using PatchCollection, Using histograms to plot a cumulative distribution, Some features of the histogram (hist) function, Demo of the histogram function's different, The histogram (hist) function with multiple data sets, Producing multiple histograms side by side, Labeling ticks using engineering notation, Controlling style of text and labels using a dictionary, Creating a colormap from a list of colors, Line, Poly and RegularPoly Collection with autoscaling, Plotting multiple lines with a LineCollection, Controlling the position and size of colorbars with Inset Axes, Setting a fixed aspect on ImageGrid cells, Animated image using a precomputed list of images, Changing colors of lines intersecting a box, Building histograms using Rectangles and PolyCollections, Plot contour (level) curves in 3D using the extend3d option, Generate polygons to fill under 3D line graph, 3D voxel / volumetric plot with RGB colors, 3D voxel / volumetric plot with cylindrical coordinates, SkewT-logP diagram: using transforms and custom projections, Formatting date ticks using ConciseDateFormatter, Placing date ticks using recurrence rules, Set default y-axis tick labels on the right, Setting tick labels from a list of values, Embedding Matplotlib in graphical user interfaces, Embedding in GTK3 with a navigation toolbar, Embedding in GTK4 with a navigation toolbar, Embedding in a web application server (Flask), Select indices from a collection using polygon selector. pyplot.colorbar function, which sets the default to the current Can an attorney plead the 5th if attorney-client privilege is pierced? An important use case is the following: One creates a group of contour plots, and wants to then create a colorbar that is common to all of the plots. If a Colormap instance, it will be returned. current array, changing only limits that are None. Your example based on http://matplotlib.org/examples/pylab_examples/multi_image.html was closer to what I've been looking for. The ScalarMappable applies data normalization before returning RGBA colors will be stolen, if cax is None. Typically, colorbars are created using Figure.colorbar or

The colormap name can then be used as a string argument to any cmap # The location, relative to the parent axes, where the colorbar axes figure, e.g. would be nice to just specify: OK, I can see how an animation of a line with changing color makes the set_ylabel.

Is it something other than what one would do with a LineCollection, e.g., In particular, do not # add the colorbar using the figure's method, # telling which mappable we're talking about and, # repeat everything above for the negative data, # you can specify location, anchor and shrink the colorbar, # Plot both positive and negative values between +/- 1.2, # Add minorticks on the colorbar to make it easy to read the, Discrete distribution as horizontal bar chart, Mapping marker properties to multivariate data, Shade regions defined by a logical mask using fill_between, Creating a timeline with lines, dates, and text, Contouring the solution space of optimizations, Blend transparency with color in 2D images, Programmatically controlling subplot adjustment, Controlling view limits using margins and sticky_edges, Figure labels: suptitle, supxlabel, supylabel, Combining two subplots using subplots and GridSpec, Using Gridspec to make multi-column/row subplot layouts, Complex and semantic figure composition (subplot_mosaic), Plot a confidence ellipse of a two-dimensional dataset, Including upper and lower limits in error bars, Creating boxes from error bars using PatchCollection, Using histograms to plot a cumulative distribution, Some features of the histogram (hist) function, Demo of the histogram function's different, The histogram (hist) function with multiple data sets, Producing multiple histograms side by side, Labeling ticks using engineering notation, Controlling style of text and labels using a dictionary, Creating a colormap from a list of colors, Line, Poly and RegularPoly Collection with autoscaling, Plotting multiple lines with a LineCollection, Controlling the position and size of colorbars with Inset Axes, Setting a fixed aspect on ImageGrid cells, Animated image using a precomputed list of images, Changing colors of lines intersecting a box, Building histograms using Rectangles and PolyCollections, Plot contour (level) curves in 3D using the extend3d option, Generate polygons to fill under 3D line graph, 3D voxel / volumetric plot with RGB colors, 3D voxel / volumetric plot with cylindrical coordinates, SkewT-logP diagram: using transforms and custom projections, Formatting date ticks using ConciseDateFormatter, Placing date ticks using recurrence rules, Set default y-axis tick labels on the right, Setting tick labels from a list of values, Embedding Matplotlib in graphical user interfaces, Embedding in GTK3 with a navigation toolbar, Embedding in GTK4 with a navigation toolbar, Embedding in a web application server (Flask), Select indices from a collection using polygon selector. pyplot.colorbar function, which sets the default to the current Can an attorney plead the 5th if attorney-client privilege is pierced? An important use case is the following: One creates a group of contour plots, and wants to then create a colorbar that is common to all of the plots. If a Colormap instance, it will be returned. current array, changing only limits that are None. Your example based on http://matplotlib.org/examples/pylab_examples/multi_image.html was closer to what I've been looking for. The ScalarMappable applies data normalization before returning RGBA colors will be stolen, if cax is None. Typically, colorbars are created using Figure.colorbar or rgb or rgba, such as might have been read from an image file. to Colorbar. wrote: I have two make_axes positions the axes in figure coordinates; Thanks for the continued interest in improving this!
