# TernaryDiagrams

This package exports a few [Makie](https://github.com/MakieOrg/Makie.jl) recipes
that can be used to construct a (relatively quick and dirty) [ternary
plot](https://en.wikipedia.org/wiki/Ternary_plot).
In all the examples that follow, it is assumed that `a1[i] + a2[i] + a3[i] = 1`.
## The ternary axis
```julia
using GLMakie
using TernaryDiagrams
fig = Figure();
ax = Axis(fig[1, 1]);
ternaryaxis!(
ax;
labelx = "a1",
labely = "a2",
labelz = "a3",
# more options available, check out attributes with ?ternaryaxis (same for other plot functions)
#= Note
Depending on the length of the axis labels, they may seem unaligned.
Use the kwarg arrow_label_rotation_adjustment to rotate them slightly.
For longer labels, use a value closer to 1 (trial and error it).
=#
)
# the triangle is drawn from (0,0) to (0.5, sqrt(3)/2) to (1,0).
xlims!(ax, -0.2, 1.2) # to center the triangle and allow space for the labels
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax) # to hide the axis decorations
fig
```
## Ternary lines
```julia
using GLMakie
using TernaryDiagrams
using JLD2
@load pkgdir(TernaryDiagrams)*"\\test\\data.jld2" a1 a2 a3 mus
a1 = a1[1:20]
a2 = a2[1:20]
a3 = a3[1:20]
fig = Figure()
ax = Axis(fig[1, 1])
ternaryaxis!(ax)
ternarylines!(ax, a1, a2, a3; color = :blue)
xlims!(ax, -0.2, 1.2)
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax)
fig
```
## Ternary scatter
```julia
using GLMakie
using TernaryDiagrams
using JLD2
@load pkgdir(TernaryDiagrams)*"\\test\\data.jld2" a1 a2 a3 mus
a1 = a1[1:20]
a2 = a2[1:20]
a3 = a3[1:20]
mus = mus[1:20]
fig = Figure()
ax = Axis(fig[1, 1])
ternaryaxis!(ax)
ternaryscatter!(
ax,
a1,
a2,
a3;
color = [get(Makie.ColorSchemes.Spectral, w, extrema(mus)) for w in mus],
marker = :circle,
markersize = 20,
)
xlims!(ax, -0.2, 1.2)
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax)
fig
```
## Ternary contours
```julia
using GLMakie
using TernaryDiagrams
using JLD2
@load pkgdir(TernaryDiagrams)*"\\test\\data.jld2" a1 a2 a3 mus
a1 = a1[1:20]
a2 = a2[1:20]
a3 = a3[1:20]
mus = mus[1:20]
fig = Figure();
ax = Axis(fig[1, 1]);
ternarycontour!(
ax,
a1,
a2,
a3,
mus;
levels = 5,
linewidth = 4,
color = nothing,
colormap = reverse(Makie.ColorSchemes.Spectral),
pad_data = true,
)
ternaryaxis!(ax)
xlims!(ax, -0.2, 1.2)
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax)
fig
```
## Ternary filled contours
Note: `ternarycontour` uses a different Delaunay triangulation scheme to
`ternarycontourf` (the former is made by me, while the latter essentially calls
`tricontourf` from Makie.
```julia
using GLMakie
using TernaryDiagrams
using JLD2
@load pkgdir(TernaryDiagrams)*"\\test\\data.jld2" a1 a2 a3 mus
a1 = a1[1:20]
a2 = a2[1:20]
a3 = a3[1:20]
mus = mus[1:20]
fig = Figure();
ax = Axis(fig[1, 1]);
ternarycontourf!(ax, a1, a2, a3, mus; levels = 10)
ternaryaxis!(ax);
xlims!(ax, -0.2, 1.2)
ylims!(ax, -0.3, 1.1)
hidedecorations!(ax)
fig
```
## Long term plans
If you use this package and run into issues, please let me know! I am planning
on extending the package to make a ternary plot axis instead of co-opting the
regular 2D axis. Before that stage though, I would like to sort out any bugs I
currently have implemented. So let me know what you think!
