According to the Laboratory Handbook of Statistical Methods (1931), we do charts or tables.
But in fact, it is not an exclusive or. We can do both at the same time. and there are also semi-graphical displays, such as stemgraphic.org (@stemgraphic)

Do you need to gain insight on your data? See the multimode? See the distribution shape? Potential issues? Check out this article about our free tool @stemgraphic

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: github.com/dionresearch/stem…)

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).

Tumblr was also degraded quite a bit. I've uploaded it to google photo:

Probably one feature that few people know about, @stemgraphic 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

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.

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.

Of course with @stemgraphic, 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, @stemgraphic has been able to do them with categorical or text too #dataviz #infoviz

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 @stemgraphic 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 @stemgraphic 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.

In the above, I mean "distance of shots when there is a goal", to be clear.
But what about looking at only the @WhitecapsHockey and @BuffaloBeauts games against each other? Buffalo is very consistent against any opponent and appears to block Minnesota's attack from distance.

A simple stem-and-leaf plot using @stemgraphic tool. Can be used from the command line, or in @ProjectJupyter notebooks or #python apps
