[Carbon Type Package]: Add IBM Plex Condensed

[mjabbink]

Carbon Charts uses the condensed in X and Y-axis and axis labels

Teams like IoT are using Carbon Charts and getting Helvetica in place of Plex Condensed in all their Bar Chart versions

Very odd... I get the correct fonts in Chrome:

But I get Helv in Safari / on mobile

Possibly because I have the fonts loaded on my laptop.

@joshblack seems like we need to add IBM Plex Sans Condensed to the font-face declarations?

@tw15egan ah do we use condensed for charts??

[tw15egan]

Yeah seems like it so we need a way to turn on the condensed styles. Doesn't look like we ship that out as it stands? Do we just need to mimic the other font-face files in type/scss/font-face, and add one in for _sansCondensed?

@tw15egan that’s my impression. We just don’t provide the google fonts @font-face declarations for condensed Plex like we do for serif, sans, and mono.

Considering we supply the sources for Serif despite not using it in Carbon/product, it seems like it we should be including it.

Do you know how / where we get the url for the fonts?

e.g.

carbon/packages/type/scss/font-face/_sans.scss

Line 21 in d31eadd

url(https://fonts.gstatic.com/s/ibmplexsans/v6/zYX7KVElMYYaJe8bpLHnCwDKhdTmvIRcdvfo.woff)

@tw15egan we just get them off google fonts. Typically when someone uses google fonts, the link they give you fetches a style sheet With the latest font face definitions. We just do that fetch a head of time and commit it. The negative side effect is that our version of Plex can get out dated. Here’s the link for they give for condensed.

https://fonts.googleapis.com/css2?family=IBM+Plex+Sans+Condensed

@tw15egan On a machine where I have Plex installed I'd get Plex on the IoT pages because the browser will locate the font locally. But if you don't have it installed you'll get the fallback fonts
