• [x] Manually tested that the website UI works as intended with different device layouts
  • (Most common is to test with typical screen sizes for mobile (320-425 px), tablet (768 px) and desktop (1024+ px), which can easily be done with your browser's dev tools)
• [x] Manually tested that everything works as intended when logged in as different users locally
  • (This can be e.g. anonymous users (i.e. not being logged in), "normal" non-member users, members of different committees, and superusers)
• [x] Made sure that your code conforms to the code style guides
  • (It's not intended that you read through this whole document, but that you get yourself an overview over its contents, and that you use it as a reference guide / checklist while taking a second look at your code before opening a pull request)
• [x] Attempted to minimize the number of common code smells
  • (See the comment for the previous checkbox)
• [x] Added sufficient documentation - e.g. as comments, docstrings or in the README, if suitable
• [x] Added your changes to the "Unreleased" section of the changelog - mainly the changes that are of particular interest to users and/or developers, if any
• [x] Added a "Deployment notes" section above, if anything out of the ordinary should be done when deploying these changes to the server
• [x] Structured your commits reasonably
  • (Some tips on this can be found in "Write Better Commits, Build Better Projects" and in the code style guides)
  • (Restructuring commits after they've already been committed, can be done using e.g. interactive rebase; see the Git docs on rewriting history)

On the third plot, some of the sewing machines appear twice

[Gunvor4]

On a normal screen, with two plots next to each other, the title is above the second plot. It would look better if it was in the middle. The two plots are also not situated in the middle of the page, which is fine, but then the title of the page should be adjusted relative to the plots, and not the page. The same issue is still there when the screen size gets smaller and only one plot is shown per row.

[Gunvor4]

In the two plots counting how many times a 3D printer or a sewing machine has been booked by someone, it looks a bit strange that there are decimals on the y-axis, since it is impossible for a machine to be booked 0.5 times. The two other plot, on the other hand, are counting hours, so there it would have been ok to see decimals. But these plots only have integers on the y-axis. The styles should be switched – the "number of times" plots should not have decimals, and the "how many hours" plots, could.

[Gunvor4]

The last plot doesn't show any numbers on the y-axis, and the axis also doesn't have a label. I guess what is shown here is the result of a calculation? Still – would it be possible to give the y-axis a label or introduce some numbers here, to make it clearer what the plot actually shows? Maybe add a label like "equipment currently in use" or "machines or workstations currently in use"?

[Gunvor4]

On the x-axis on the last plot – the numbers are tilted, like for the names of 3D-printers or sewing machines. But on this plot, the only thing the x-axis shows are time points, which are shorts, so tilting them looks a bit strange.

[Gunvor4]

I don't think you need a colon after the title of a plot ;-)

[Gunvor4]

It might be an idea to sort the printers, either alphabetically, or to keep the same order as they appear in on the website. Now I added some fake ultimakers, then some fake raise3D printers, a fake SLA printer, and then some fake ultimakers again, and now I have the ultimakers at both sides of the plot, with raise 3D printers and SLA printers in the middle.

[Gunvor4]

Aaaand now I'm done! :-) Sorry about being nitpicky :-P
