Parcoords fonts #1624

Support for specifying fonts for parcoords dimensions. Example, see JS code 8..12:http://codepen.io/anon/pen/QvdwpX

Why do you need to call Lib.coerceFont twice?

... as we're (slowly) trying to make our code look more like the standard style - which disallows multiple blank lines.

Ah got it, thanks!

Btw HUGE fan of standard style

Now that there aren't giant outstanding PRs, might be time to revisit: #1371 (though I'm increasingly intrigued by prettier which is fundamentally different from a linter)

--> The selling point of prettier is that you don't have to adhere to any style at all because it doesn't present you with errors. It just makes things consistent. 😄

True. But you have to do some non-trivial src vs build file trickery.

... adding pre-commit hooks is hardly simplifying anything IMHO.

See #1629 for quick experiment. It replaces lint and lint-fix with prettier equivalents and adds a precommit hook that formats staged files without ever having to manually add a precommit hook.

I think we're bikeshedding #950 (comment)

This is not our usual pattern.

The default font size is inherited from fullLayout.font.size directly as here or times a scalar like here.

The purpose was to have smaller fonts than what would come from the layout defaults, which would result in overly big numbers, looked really bad. The dimension labels and tick numbers need to be quite small by default, e.g. around 10px. It's achieved by parcoords/attributes specifying these sizes. Is there another way of saying, 'take layout font values but don't adopt large fonts unless the user wants it, in which case they specify it on eg. labelfont?

Lib.coerceFont('labelfont', coerce, layout.font);

should be enough, no?

I could do that. The consequence is that the tick and dimension label fonts would be too large:

It's even worse if the user specified a larger font centrally, e.g. size 16:

Since I can go either way, pls confirm if I should preserve the current fontsize-moderation logic or use the simpler logic. Consistency matters a lot on one hand, and having ergonomically good defaults is also valuable.

Ha. I see 10px was used before. I should've caught that. Elsewhere in plotly.js this would be 12px.

I guess we'll have to keep it this way until v2 😬

@monfera is removing that font-weight setting on purpose? Unsurprisingly, it makes the image tests fail.

As we discussed about font standardization... I assumed, perhaps incorrectly, that we don't want to customize it. I do have a preference for the lower font weight as in the case of parcoords the shape of line distribution is more important than the best readability so it's fine to keep the weight=100 but with configuration, the user can probably control the font anyway.

We don't set font-weight anyway in our code - though inputting text as <b>text</b> effectively does that.

This is another thing I wished I would've noticed while reviewing your first parcoords PR. Oh well. I think it's best to drop font-weight and make parcoords look a little more plotly-esque.

Cool, in this case I could guess, if a bit late, how you'd go about it :-)

- N.B. this keeps the 10px default

+        size: Math.round(layout.font.size * (10 / 12)),


@monfera this is what I came off with.

As you pointed out, changing the font size default to 12 makes most parcoord graphs look less-than-optimal. We should fix that text-overlapping problem at some point though - similar to how we do it currently in cartesian axes. But that's for another PR. So, the 10px default value remains.

But, to make this a little more plotly-esque, we make the parcoord font size scale linearly with layout.font similar to what's done for axes titlefont.

Thanks @etpinard, also for the pointer!

@monfera are you ok with my changes?

monfera · 2017-05-09T14:22:39Z

@etpinard yes, thank you, I should have indicated this more unambiguously in my reply.

monfera · 2017-05-09T14:23:22Z

Also, overall, looks good!
