Did you know stemgraphic also has a wide range of semi-graphic displays you can use from the console, in a python or ipython session (or in a notebook even, see: )

or using the digit glyph for other languages. For example in this case I used charset='arabic' on a stem-and-leaf plot (stem_text)

The unicode charset support is also pretty handy to have, say, "bold" text. Even in a terminal. Simply add charset="bold" to the call (heatmap in this example with zipcodes).

Probably one feature that few people know about, provides a bunch of text and semi-graphic displays. From the command line or from ipython, or in the notebook, but as text. For example, good old tally chart

And finally, if you use xtem, mlterm or any other terminal supporting Sixel graphics in a text environment, then stem has a -o stdout graphical support you will appreciate. Still command line, but with graphics inside your terminal.

Heatmatrix are when you want all the numbers in a filled matrix. But for patterns, you might prefer a compact form with the zeros removed: Again, this is using the stem command line tool from stemgraphic, but using text_heatmap as type.

You can also use the stem command line if you are not a programmer! For example, how about a stem-and-leaf heatmatrix showing the count of stem/leaf pairs. In this case, names of Titanic survivors (from excel spreadsheet) starting with stem+leaf letters

Of course with , you can do stem-and-leaf plots in text mode, wide format now. Millions of rows in a few seconds on my laptop. And, if you’ve missed it, has been able to do them with categorical or text too

Also, violin plots seem to suggest plays outside of the rink... Not the case with stem-and-leaf. Here's an example with NWHL data, 2017 season, using to plot it (using pandas to select year and team, BOS), in a back to back format, for X coordinate:

That's a back to back in case you are wondering. Distances are read directly on the stem and the fractional feet are the leafs. gives the *exact* distribution, unlike a box plot or violin plot.
