Hello,

I am trying to determine how I can increase the line thickness of the lines in the legend.

Please consider the following MWE and resulting image. The lines in the legend are too short and it is hard to tell which is dashed and which is solid (I realize in this case the markers can be used to discern them, please ignore that for the sake of the example).

How can I increase the little segments of line in in the legend so it is clearer which line style corresponds to which legend entry?

```julia
using CairoMakie, LinearAlgebra

x = LinRange(0, 1, 10)
y1 = sin.(2π * x)
y2 = x .^ 2

begin
    fig = Figure()
    ax = Axis(fig[1, 1])
    scatterlines!(x, y1, label="Line 1")
    scatterlines!(x, y2, label="Line 2")
    axislegend("My Legend", position=:lb)
    fig
end

```

This post made me laugh out loud. It’s like Makie is _trying_ to mess with you.

You can increase the width of the `patchsize` of the `Legend` which will increase the line widths as well.

It’s far from the defaults though… I think @TI36XPro has a lot of configuration that’s not included in the MWE. With the given code I see this:

We can adjust the legend line length using `patchsize` as suggested by @jules, replacing the `axislegend` line with

```julia
axislegend("My Legend", position=:lb, patchsize=(50,20))

```

I tried `axislegend("My Legend", position=:lb, patchsize=10)` and I get the following error `ERROR: BoundsError: attempt to access Int64 at index [2]`

Edit: Nevermind. Didn’t realize `patchsize` has to be a tuple. I’ve fixed it. Ended up using `patchsize=(50,10)` for now. Thank you!

Correct - I forgot I had a theme applied separately that is not included in the MWE. Although the theme makes no changes to `patchsize` so still not clear how or why it got so small. Either way, it is fixed!

I think you just themed all the other stuff to be quite big 🙂
