Vegalite.jl: use dots for separation sign

Is there a setting to use . instead of , for digit separation in the resulting plot itself?

(E.g., 1.000 instead of 1,000 for a thousand.)

Alternatively, is there a setting to use a space character?

You can use labelExpr as in the following example:

using VegaLite, DataFrames

data = DataFrame(
    x=[1,2,3,4,5,6,7],
    y=[10,30,missing,15,missing,40,20]
)

data |>
@vlplot(
    mark={
        :line,
        point=true
    },
    x={"x:q",axis={labelExpr="format(datum.label,'.1f')"}},
    y=:y
)

which changes the x labels from integer to floats.
The format specifier is a d3-format specifier:

And see also

Changing . to , is probably a locale setting in d3-formats, but I didn’t found out how to set them from VegaLite/Vega

So, e.g. if you can’t find the proper d3-format, you can provide the labels explicit in the data, e.g. based on the above example:

data[!,:labels]=["1,0","2,0","3,0","4,0","5,0","6,0","7,0"]
data |>
       @vlplot(
           mark={
               :line,
               point=true
           },
           x={"labels:n",title="x"},
           y=:y
       )

The details depend on the type of plot you are going to create.

Thanks, though it seems very cumbersome in Vegalite like that.

VegaLite is somehow cumbersome.
VegaLite.jl is already less cumbersome :wink:

Indeed, and most useful.
