I’m trying to produce a 3D surface plot in R, and I would like to use superscripts, subscripts and greek letters in the plot title and axis labels.
I am using the following code:
p <- plot_ly(x = x_vec, y = y_vec, z = z_martix, type="surface" ) %>% layout(title = '<br>x<sup>2</sup> x<sub>2</sub> Γ', scene = list(xaxis = list(title = 'x<sup>2</sup> x<sub>2</sub> Γ'), yaxis = list(title = "y"), zaxis = list(title = "z") ))
I noticed that while superscript works in both the title and the axis label, subscript works only in the title. In addition, the capital greek letter gamma (whose html entity is
Γ) is displayed as
"&Gamma"; in the title, and not displayed at all in the axis label.
