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

I think xy[4] = .25, val[0] should be commented in /matplotlib/widgets. py", line 915, in set_val
as it prevents to initialized value for RangeSlider

Code for reproduction

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import RangeSlider

# generate a fake image
np.random.seed(19680801)
N = 128
img = np.random.randn(N, N

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

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

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:

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.

The code that selects and renders the different geos is here in the THREE.js code

I don't know quite where/how to inject the mesh definition compatible with the data file of this form, but i

This shouldn't happen

This should be a good beginner issue :)

Test for generate_cell_offsets doesn't actually check anything:

What should we add?

The maximum Eady growth rate (EGR) is a measure of baroclinic instability. I couldn't find a function in MetPy which implements that. NCL has a function implemented to do that here. The formula is not complicated to implement.

However, does MetPy also considers making the NCL functionali
