[FEATURE] Separate colorbars for multiple row annotations

[sergiumocanu]

Hi,

Thank you for making an awesome heatmap package integrated with plotly.

I'm wondering, is it possible to separate the colorbars of multiple row annotations into their own separate colorbars?

row_side_colors <- data.frame(iris[, 4:5])
heatmaply::heatmaply(
    iris[, 1:3],
    plot_method = "plotly",
    row_side_colors = row_side_colors
)

Here both annotations are combined in one colorbar.

Thanks in advance!

Yes, mostly, although it is sometimes inconsistent. See eg https://stackoverflow.com/questions/60458220/two-or-three-colorbars-for-one-plot-in-plotly

Thank you @alanocallaghan for the suggestion. However, that's not really the same thing. They are just plotting a second scatter plot trace and adding its corresponding colorbar.

In my example, the colorbars are combined together into one, even though I would like Species and Petal.Width to have their own bars.

You asked

I replied with an example documenting use of multiple colorbars with a note about my experience in trying to implement this myself in heatmaply, so I can revisit this later. I wasn't trying to say they were identical
