Custom format for the tip mark?

[mbostock]

Like #1596, but for the tip mark.

[net]

Isn't custom formatting supported?

{ channels: { height: d => `${d.height} in` } }

[Fil]

It's a (hacky) way to address the task for now, but we'd prefer a way to format the display of values in the tip, rather than having to derive extra channels of formatted strings.

[mbostock]

And to add to what @Fil said, the channels option is overriding the channel, so overriding the x channel for example would interfere with the placement of the tip.

It would be very convenient to have it

I'm making my first steps with plot, and I would like for example to have in bold the first line of tooltip (it’s a title) and to add a hyperlink at the end of the tooltip text.

@aborruso That should probably be a separate issue to allow the title channel (or similar) to contain rich text or markup. Since the tooltip is rendered in SVG that won’t be easy.

I'll do it. Thank you again

@mbostock @Fil it is super impressive how active you both are in supporting and enhancing d3/plot. Plot has progressed very nicely since you first released it. I am building a solution using plot and just ran into this tooltip issue. I'm going to post what I would like to be able to create via the tooltip rendering (even if it won't be possible to do for some time):

These current values are very small, but the tip shows them as zero

[mbostock]

@jonhelfman You could try a y scale transform to multiply by 1e6 and change the units.

Thank you for your comment.
I see the smiling face, so I guess you are joking, but I'm not really sure.
I think what would be nice is a way to set tickFormat:"~s" on the tooltip, right?
