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, hov_color = NULL, hov_alpha = NULL, ns_color = NULL, ns_alpha = NULL, sel_color = NULL, sel_alpha = NULL, lname = NULL, lgroup = NULL, ...)
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 |
hov_color |
Color to use to stroke lines when they are hovered. |
hov_alpha |
Transparency value for the line when it is hovered. |
ns_color |
Color to use to stroke lines when they are not selected. |
ns_alpha |
Transparency value for the line when it is not selected. |
sel_color |
Color to use to stroke lines when they are selected. |
sel_alpha |
Transparency value for the line when it is selected. |
lname |

Additional parameters for fine control over line properties. See "Additional parameters" below. |
line_join | How path segments should be joined together. One of 'miter' 'round' 'bevel'. |
line_cap | How path segments should be terminated. One of '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. |
