        # CairoPlot

Simple plot tool based on [JuliaGraphics/Cairo.jl](https://github.com/JuliaGraphics/Cairo.jl), which itself is an adaptation (binding) to Julia of the [Cairo](https://github.com/JuliaGraphics/Cairo.jl) C library.

The aim here is to have a plotting tool with minimal dependencies and fast.

It is still a work in progress and it is a not a registered package yet.

Ops, I just found out that there is already the package [JuliaGraphics/Winston.jl](https://github.com/JuliaGraphics/Winston.jl) that does that. 🤦‍♂️

Hmm, but `Winston.jl` plots are not always as pretty; the identation for multiline plots are not correct, and I don't think the background color can be changed to dark, which is what suits Discord best (for the [Humans-of-Julia/HoJBot.jl](https://github.com/Humans-of-Julia/HoJBot.jl), which was the whole point for starting this). So I definitely should continue this project.

The package can be added with

```julia

pkg> add https://github.com/rmsrosa/CairoPlot.jl

```

## Examples

```julia

x = range(0, 10π, length=200)

y = sin.(x)

xticks = 0:5:30

yticks = -1.0:0.25:1.0

c = crplot(x, y; xticks, yticks, title = "Plot of a sine wave")

write_to_png(c,"sineplot.png")

```

![sine plot](scripts/sineplot.png)

```julia

x = range(0, 10π, length=30)

y = sin.(x/5) .+ 0.3randn(length(x))

c = crplot(x, y; width = 600, height = 200, title = "Perturbation\n of a sine wave")

write_to_png(c,"perturbedsineplot.png")

```

![perturbed sine](scripts/perturbedsineplot.png)

```julia

title = "Scattered perturbation\n of a sine wave"

x = range(0, 10π, length=100)

y = sin.(x/5) .+ 0.3randn(length(x))

c = crplot(x, y; plotstyle = :scatterplot, width = 600, height = 200,

    title = "Scattered perturbation\n of a sine wave")

write_to_png(c,"scatteredperturbedsineplot.png")

```

![scattered perturbed sine](scripts/scatteredperturbedsineplot.png)

```julia

xd = today():Year(1):today()+Year(20)

yd = rand(length(xd))

c = crplot(xd, yd; title="Prediction for the next 20 years")

write_to_png(c,"20years_future.png")

```

![20 years ahead](scripts/20years_future.png)

```julia

xd = today()-Month(1):Day(1):today()

yd = 100.0 * rand(length(xd))

c = crplot(xd, yd; xticks = 5, yticks = 10, title="One month evolution")

write_to_png(c,"onemonth_past.png")

```
