I am trying to reproduce a simple plot with a slider from the Makie docs.
I read in the Makie basic tutorial
To see the output of plotting commands when using CairoMakie, we recommend you either use an IDE which supports png or svg output, such as VSCode, Atom/Juno, Jupyter, Pluto, etc.,
So I pasted the slider example code into a Jupyter notebook:
using CairoMakie f = Figure() Axis(f[1, 1], limits = (0, 1, 0, 1)) rs_h = IntervalSlider(f[2, 1], range = LinRange(0, 1, 1000), startvalues = (0.2, 0.8)) rs_v = IntervalSlider(f[1, 2], range = LinRange(0, 1, 1000), startvalues = (0.4, 0.9), horizontal = false) labeltext1 = lift(rs_h.interval) do int string(round.(int, digits = 2)) end Label(f[3, 1], labeltext1, tellwidth = false) labeltext2 = lift(rs_v.interval) do int string(round.(int, digits = 2)) end Label(f[1, 3], labeltext2, tellheight = false, rotation = pi/2) points = rand(Point2f, 300) # color points differently if they are within the two intervals colors = lift(rs_h.interval, rs_v.interval) do h_int, v_int map(points) do p (h_int < p < h_int) && (v_int < p < v_int) end end scatter!(points, color = colors, colormap = [:black, :orange], strokewidth = 0) f
This causes the cell to output the following static image.
Needless to say, I want to be able to drag around the sliders. So, I went back to the basic tutorial (same link as above) and read the following:
GLMakie can open interactive windows, or alternatively display bitmaps inline if
I thought: “Aha, so if I use the GLMakie backend instead of CairoMakie, I can get Makie to open an interactive window! That’s what I need. Seems weird that the documentation slider example would use CairoMakie, but let’s try it.”
So, I changed the code above to the following:
using GLMakie GLMakie.activate!() Makie.inline!(false) # Probably unnecessary? f = Figure() # ...
but this produces the same, static figure as above, except with lower resolution:
(The resolution is actually quite bad—look at the decimal point in
- How do I actually get Makie to open the promised “interactive windows”?
- Can it be done in CairoMakie, or do I have to use GLMakie?
- If it’s the latter, then why does the slider example in the documentation use CairoMakie at all?
