l_layer_text.RdLoon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.
layer a single character string
l_layer_text(widget, x, y, text, color = "gray60", size = 6, angle = 0, label = "text", parent = "root", index = 0, ...)
| widget | widget path name as a string |
|---|---|
| x | coordinate |
| y | coordinate |
| text | character string |
| color | color of text |
| size | size of the font |
| angle | rotation of text |
| label | label used in the layers inspector |
| parent | group layer |
| index | of the newly added layer in its parent group |
| ... | additional state initialization arguments, see
|
layer object handle, layer id
As a side effect of Tcl's text-based design, it is best to
use l_layer_text if one would like to layer a single character
string (and not l_layer_texts with n=1).
