Gadfly Boxplot w/o DataFrames

New to Julia
1

I was giving Gadfly a shot, plotting some simple data to see how it works. Most of what I tried works fine and the Package seems amazing. However, I tried testing its boxplot functionality and ran into this issue.

p = plot(x=["Label"], y=randn(10), Geom.boxplot)

So, a similar syntax works fine with other Geom options. But for boxplot I get the following error:

Error showing value of type Plot:

Following the hint [Base.LogicalIndex(Bool[1])], I decided trying to wrap the data in a list:

p = plot(x=["Label"], y=[randn(10)], Geom.boxplot)

however that still gives me an error:

Error showing value of type Plot:

I got it working after massaging my data into a DataFrame, but I’d rather avoid it. So the question is: is there really no way to use Geom.boxplot without DataFrames?

Try either

p = plot(x=repeat(["Label"],10), y=randn(10), Geom.boxplot)

or

p = plot(y=randn(10), Geom.boxplot)

or

p = plot(x=rand([1,2],10), y=randn(10), Geom.boxplot)

Yeah, I had tried the second suggested solution before

but then I was missing the “Label”.

On the other hand, solutions 1 and 3 work like a charm and now I know repeat and rand([1,2],10). :slight_smile: Thanks @jmboehm!
