For my thesis, I would like to have the option to count supplementary figures separately, but be able to mention them within the main text, without showing them.
If I simply add a figure in my appendix chapter as such:
#figure(
grid(
columns: 2,
column-gutter: 4mm,
[#image("../figures/dummy_image.svg", width: 70%)],
[#image("../figures/dummy_image.svg", width: 70%)],
),
caption: [#lorem(50)],
) <figure_supplementary_test>
and refer to it as @figure_supplementary_test[Supplementary Figure] in the text, it works but the figure count is of course not starting from 1 for the first Supplementary Figure but from its rank in all #figures in the document.
So for my first supplementary figure mentioned, I currently get a working link of the format (Supplementary Figure 7), as it is the 7th figure in my text, but I would like to have a working link of the format (Supplementary Figure 1).
Can I define a new figure type for this? Can I simply add an alternative counter?
You can use the kind parameter of the #figure() function in Typst to specify a separate counter. Then use the supplement parameter to define the label text for references.
Example:
= Main Text
See @figure_supplementary_test.
= Appendix
#figure(
grid(
columns: 2,
column-gutter: 4mm,
image("../figures/dummy_image.svg", width: 70%),
image("../figures/dummy_image.svg", width: 70%),
),
caption: lorem(50),
supplement: [Supplementary Figure],
kind: "supp",
) <figure_supplementary_test>
A set-rule can be used if you want to adjust the kind and supplement parameter default values for the rest of the document:
...
= Appendix
#set figure(kind: "supp", supplement: [Supplementary Figure])
#figure(
grid(
columns: 2,
column-gutter: 4mm,
image("../figures/dummy_image.svg", width: 70%),
image("../figures/dummy_image.svg", width: 70%),
),
caption: lorem(50),
) <figure_supplementary_test>
You can revert to the original behavior for figures by setting kind and supplement parameters back to auto, if required.
