I can’t figure out how to show the actual values on a bar chart in VegaLite, I tried adapting the examples but clearly I don’t understand what options are necessary to achieve what I want.
I’m able to do each layer more or less how I want it, but I don’t understand how can I get them overlayed and with independent coloring.
using VegaLite, Random, DataFrames
function syntdata(N=50)
Random.seed!(1);
df = DataFrame()
df.Cat1 = [rand([:A,:B,:C]) for _ = 1:N]
df.Cat2 = [rand([:D,:E]) for _ = 1:N]
df.Cat3 = [rand([0,1]) for _ = 1:N]
return df
end
function testplot2(df,t=:BP)
bp = @vlplot(:bar, #barplot
x={aggregate="count",field="Cat3:n",stack="normalize"},
y="Cat1:n",
color="Cat3:n")
tp = @vlplot(:text, # text labels
x={aggregate="count",field="Cat3:n",stack="normalize"},
y="Cat1:n",
color="Cat3:n",
text="count(Cat3)"
)
if t == :BP
mp= bp
elseif t ==:TP
mp = tp
else
mp = bp + tp
end
df |> @vlplot(
facet={row={field="Cat2", type="nominal"}}
) +
(
mp
)
end
df = syntdata()
testplot2(df,:BP) # only bar
testplot2(df,:TP) # text labels
However, combining only shows one layer(?)
testplot2(df,:Both)
Output is similar to the last one.
I tried several things, I think i may need config={resolve={scale={color="independent"}}} to get different text color for example, but tried to make the example above as simple as possible while maintaining the same structure, but I don’t understand what I need to do to make the text overlay the bars.
