colorbar title instead of "z"

[ccjake]

I would like to change the title of the right side colorbar, but layout method in plotly failed.

could you please provide the code that is not working so we can look into it?

Hallo,

Thanks for reply. I took a closer look at the source code. You are using add_trace to create the colorbar instead of using the coloraxis or something come with plotly, so I think that's the reason, why the layout did not work. I have changed a little code in the source code and now it works.

p <- ggseg3d(.data = example1Data,
             atlas = desterieux_neu,
             colour = "wert", text = "beschreibung",
             surface = "LCBC",
             palette = c("red" = 1, "yellow" = 2, "blue" = 3),
             hemisphere = c("left","right"),
             show.legend = FALSE) 

 %>% layout(coloraxis=list(colorbar=list(title=list(text="not work"))))

The above code cannot change the title.

p <- ggseg3d(.data = example1Data,  
             atlas = desterieux_neu,
             colour = "wert", text = "beschreibung",
             surface = "LCBC",
             palette = c("red" = 1, "yellow" = 2, "blue" = 3),
             hemisphere = c("left","right"),
             show.legend = FALSE)
f <- get_farbe(c("red" = 1, "yellow" = 2, "blue" = 3))
dt_leg <- dplyr::mutate(f, x = 0, y = 0, z = 0)
p = plotly::add_trace(p, data = dt_leg, x = ~x, y = ~y,
                      z = ~z, intensity = ~values,
                      colorscale = unname(dt_leg[,c("norm", "hex")]),
                      colorbar=list(title=list(text="mm")), type = "mesh3d")

The second piece of code can chang the title rightly, they are basically the code in "ggseg3d()" . Maybe it's not the best way, but it works on me.

Best wishes.

Hey!

Thanks for digging into the code and finding the culprit, and also providing a solution.

I have now added an argument where you can control the colourbar in the add_trace for the colourbar. It's in commit 5fc8fbf52aa.

Check that out and see if that behaves more like you expect :)

Hallo,

Yes, it works perfectly. Thanks for update!
