postcrossplot
points for the different solutions. If there is only one solution, the values in the
specified points are displayed in the x-axis range [0 1].
Line plots on domains (1D, 2D, 3D) Plot of an expression on a set of connected 1D
domains (edges in 3D, boundaries in 2D and subdomains in 1D). If Linxdata is
not specified, this is done by folding out the arc length of the 1D domain to the
x-axis of the resulting plot, and letting the value of the expression be set on the
x-axis. If dom contains more than one domain, the different arc lengths are just
added to each other on the x-axis. In this case, the domains have to be connected
and so that not more than two selected domains meet in the same vertex.
If Linxdata is specified, this is the quantity on the x-axis in the resulting plot. Using
Linxdata, you can project cross-sections to, e.g., the x-axis by setting Linxdata to
x.
The direction of the path is so that the start point is the point along the path with
lowest geometry vertex number. If the selected domains form a closed curve, so that
this point is also the end point, the direction is in the direction of the domain with
lowest number.
If there are several solutions (that is, Solnum or T is a vector), the curves for the
different solutions can be either plotted in the same x-y-plot or can be extruded
along the third axis to generate a surface. This is controlled by specifying either the
property Lindata or Surfdata.
Line plots on cross-sections (2D, 3D) In 2D and 3D, plot of an expression along a
straight line, defined between the two points in dom, in the geometry. The points in
dom are regarded as the end points of the cross-section line and are the x-axis limits
in the resulting plot, hence if the line between the two specified points do not
intersect the geometry, the resulting plot will be empty.
Surface plots on domains (2D, 3D) Plot of an expression on a boundary in 3D or on
a set of subdomains in 2D. In 3D, if Surfxdata and Surfydata are not specified,
the boundary is plotted in an x-y-plane where x and y correspond to the
(s,t)-parameters of the boundary. If Surfxdata and Surfydata are specified, these
represent the quantities on the x- and y-axis in the resulting plot. Using Surfxdata
and Surfydata, you can project a cross-section to, for example, the x-y-plane of the
geometry by setting Surfxdata to x and Surfydata to y. If there are several
solutions, all plots for the different solutions are displayed along the third axis, as a
slice plot. In 3D, dom must be a single integer.
