ly_contour {rbokeh} | R Documentation |
Computes and draws contour lines.
ly_contour(fig, z, x = seq(0, 1, length.out = nrow(z)), y = seq(0, 1, length.out = ncol(z)), nlevels = 10, levels = pretty(range(z, na.rm = TRUE), nlevels), color = "black", alpha = 1, width = 1, type = 1, lname = NULL, lgroup = NULL, visible = TRUE, ...)
fig |
figure to modify |
z |
a matrix containing the values to compute contour lines for |
x, y |
locations of grid lines at which the values in |
nlevels, levels |
parameters sent to |
color |
color to use to stroke lines with - a hex code (with no alpha) or any of the 147 named CSS colors, e.g 'green', 'indigo' |
alpha |
transparency value for the line between 0 (transparent) and 1 (opaque) |
width |
stroke width in units of pixels |
type |
an integer between 1 and 6 matching the |
lname |
layer name |
lgroup |
layer group |
visible |
should the layer be visible? |
... |
additional parameters for fine control over line properties (see "Additional parameters" below) |
line_join | how path segments should be joined together 'miter' 'round' 'bevel' |
line_cap | how path segments should be terminated 'butt' 'round' 'square' |
line_dash | an integer between 1 and 6 matching the lty property in par or an array of integer pixel distances that describe the on-off pattern of dashing to use |
line_dash_offset | the distance in pixels into the line_dash that the pattern should start from |
