Ngl.get_bounding_box
Retrieves the NDC bounding box values for the given object.
Available in version 1.3.1 or later.
Prototype
top,bottom,left,right = Ngl.get_bounding_box(plotid)
Arguments
plotidThe identifier returned from Ngl.open_wks, or any PyNGL function that returns a PlotId.
Return values
top, bottom, left, rightFour scalars representing, in NDC space, the topmost, bottommost, leftmost, and rightmost edges of the given plot's space.
Description
This function returns the bounding box values that enclose the given plot object. The bounding box is different than the viewport resources vpXF, vpYF, vpWidthF, vpHeightF, as it includes the area around the titles, tickmarks, tickmark labels, labelbar, etc.
The first argument is a PlotId and the second argument is the resource whose value you want to retrieve.
