This is really nice!

Although, it shows another opportunity to make it even nicer. In the new graph, it does down to -10 on the vertical, where the tick mark overwrites the horizontal 0.0 label. It looks like the plot points could also overwrite the labels if they descended that far, too. so, the next incremental enhancement would be to adjust the horizontal labels to be below the min Y locations, right?

Hi!

Milton did a wonderful improvement of Grapher.
Consider the following expression:
((1 to: 20) collect: [ :v | 50 atRandom - 5.1 ]) plot

It produces:

As you can see, the horizontal bar is not in the 0 on the Y axis. And this is quite a problem actually.
Excel does it much better. This is now fixed, in the last version of Roassal we have

Milton has implemented an optimization algorithm that identify the optimal minimum & maximum value on the axis, and the optimal number of ticks, to have a pleasant reading.

Enjoy!

Cheers,
Alexandre
