circle_scale_legend {tricycle} | R Documentation |
This function is a helper function to create the cyclic ggplot color legend.
circle_scale_legend(hue.colors = c("#2E22EA", "#9E3DFB", "#F86BE2", "#FCCE7B", "#C4E416", "#4BBA0F", "#447D87", "#2C24E9"), hue.n = 500, alpha = 0.6, y.inner = 1.5, y.outer = 3, y.text = 3.8, ymax = 4.5, text.size = 3)
hue.colors |
The string vector gives the cyclic colors. The first color should look very similar to the last one. Default: c("#2E22EA", "#9E3DFB", "#F86BE2", "#FCCE7B", "#C4E416", "#4BBA0F", "#447D87", "#2C24E9") |
hue.n |
The number of breaks of color scheme. Default: 500 |
alpha |
The alpha value (transparency). Default: 0.6 |
y.inner |
The radius of inner circle of the donut. Default: 1.5 |
y.outer |
The radius of outer circle of the donut. Default: 3 |
y.text |
The radius of text position. Default: 3.8 |
ymax |
The value control the border of the legend. Default: 4.5 |
text.size |
The size of the text Default: 3 |
The function will make a donut shape to serve as the cyclic color legend. The arguments should match the argument used in plot_emb_circle_scale
.
