[R] How to keep legend a)outside the plot and b) horizontal

Community Support

Hello,

I’m using RBokeh, which is very nice. I would like to add a legend outside the plot (which can be done in bokeh)

Currently this is what I have

        a <- figure(width=400, height=300, logo=NULL,

                    tools=c("hover","box_zoom","reset"),

                    xlab = "Date",ylab=VLAB, legend_location="bottom_left")

        a <- ly_lines(a, x = date, y=V, data=d, color=Os, hover=list(date=date, value=V),line_width=1)

        if(!is.null(ylim)) a <- y_range(a,dat=ylim)

        a <- theme_legend(a,border_line_color='white')

  1. how can i place the legend outside?

  2. How can i make the legend background transparent (assuming (1) is not possible)

I’m using rbokeh version: 0.4.3

Thanks much in advance

In the development branch, you can now specify the background transparency of the legend (I believe this is new in Bokeh 0.12 and that’s why it isn’t available in the version you are using).

devtools::install_github(“bokeh/rbokeh@dev”)

figure() %>%

ly_points(Sepal.Length, Sepal.Width, data = iris,

color = Species, glyph = Species) %>%

theme_legend(background_fill_alpha = 0.5)

I’m hoping to have all these updates merged to master and released to CRAN by the end of the week.

I’m also looking into how to make the legend outside the plot.
