plotting

As a follow-up to #11540, we would like to add metadata to as many examples as possible. This will not only make the examples more usable as they are right now, but it will also open up new possibilities to search for and crosslink examples.

For the purpose of this issue, 'standalone examples' are all .py files in these folders in this repository:

• examples/plotting/file
• `examples/mode

Bug summary

For Axes.vlines(), when I want to use axes coordinate for ymin / ymax, as suggested in blended transformation, ymin is incorrectly treated as data coordinate.

Axes.hlines() has a similar problem with xmin.

Code for reproduction

# Sample derived 

it's becoming more time-consuming and error-prone to manually re-test all the demos following internal refactorings and API adjustments.

now that the API is fleshed out a bit, it's possible to test a large amount of code (non-granularly) without having to simulate all interactions via Puppeteer or similar.

a lot of code can already be regression-tested by simply running all the demos and val

It is currently a pain to use an OxyPlot.WinfowsForms.PlotView with a transparent background: it throws if you set its BackColor to transparent. To avoid this, it is necessary to set the ControlStyles.SupportsTransparentBackColor style to true on the PlotView; however, Control.SetStyle is protected, so consumers must resort to reflection or extending PlotView to do so. This could be

Annotations don't look good in a Heatmap with a large amount of data and those that are rendered in the high values range are barely visible with the default color map. Heatmaps generated with the Bokeh backend don't have annotations by default.

See this example taken from the reference gallery:

I think it could be useful, when one wants to plot only e.g. class 1, to have an option to produce consistent plots for both plot_cumulative_gain and plot_roc

At the moment, instead, only plot_roc supports such option.

Thanks a lot

What is the feature ?

I'm trying out this library for the first time and there's some places where it would be delightful to have shorthand functions:

1. Shorthand functions for Pos: Pos::top_right, Pos::bottom_right, Pos::bottom_center etc..
2. Short way to set colors for components. Currently, lots of boilerplate is required for e.g. white-on-black plotos

I don't think this is a duplicate ticket, even though it's quite an obvious feature after that cat demo at SciPy2018.

As I understand, the LineString type allows the user to plot multiple disconnected lines in the same plot call. However, there is no documentation to reflect this. We should add some, and possibly consider adding documentation (in the docs of lines, surface, heatmap, etc.) about which types they accept. Possibly also a listing of convert_arguments signatures which are applicable to each

I get the following warning when I use Plots with the Plotly backend:

┌ Warning: PlotlyBase 0.8.18 is not compatible with this version of Plots. The declared compatibility is 0.7.

Describe the bug, what's wrong, and what you expected.

I just did pip install pyvista, but afterwards noticed that meshio was not included. this is pyvista 0.34.1 on Windows 10, python 3.7.5, using pip 19.2.3. I retried (fresh venv, et cet) with pip 22.1.1 and same result.

Steps to reproduce the bug.

What should we add?

Currently, metpy.interpolate.cross_section only operates by interpolating to a geodesic between specified start and end points. This becomes problematic when:

• Data are not georeferenced (e.g., idealized cloud models)
• User wants a straight path in the projection of their data (e.g., a rhumb line in lat/lon data)
• User seeks one of the dimensions of target points t
