I don't think non-uniformity was the issue. Rather Frank doesn't like the default spacing of base graphics, esp. around the axis text and plot extent... But we offer much nicer spacing via themes; c.f. the reduction in whitespace in the rhs plot. (This is automated, but can be further customized.)

#rstats #econsky PSA: The next release of `fixest` will include some important changes (plus cool new features).
E.g. Fixed-effects regs will now default to 'iid' SEs rather than clustered. github.com/lrberge/fixe...
You can install and test drive the dev version from R-universe; see the README.

4. Better NSE support means less typing for plots with x/ymin and x/ymax values, e.g. coefficient plots.
(We plan to expand this smart NSE passing to equivalent arguments like weights and subset in a future release.)

3. Customizing axis labels is now a lot easier thanks to a couple of convenience functions documented here: grantmcdermott.com/tinyplot/man.... You can specify breaks, use formatting shortcut symbols, or even pass custom formatting functions.

1. We've added support for more plot types, including barplots. This was one of the last remaining "canonical" base plot types that we've wanted to cover. You can do regular stacked or dodged plots, as well as fancier pyramid / centered barplots. grantmcdermott.com/tinyplot/man...

The main `tinyplot()` function (shorthand alias: `plt()`) has also gained some new features and arguments. For example, the `flip` argument allows you to flip the axes of any plot type.
