[Scilab-users] Request for suggestions with plotting.

[Adrian Weeks]

Hi All,

I wonder if anyone could suggest a solution to this problem?

I want to:

                Create a figure.                                                                                 This remains fixed.          This I can do.
                Create four axes within the figure.                                            These remain fixed.        This I can do.

                In each of the four axes plot two reference curves.           These remain fixed.        This I can do.

                Repeatedly call a function A
which calls an inner function B
which plots a curve in each of the four axes having deleted the ones it plotted on the previous call of A.                               This I can't do.

The idea is that the figure, axes and reference curves remain in place while the temporary curves are repeatedly deleted and re-plotted to allow an 'animation' showing the progression of the curves.

I can't see a way to pass and delete the handles to the polylines produced by plot2d / gce.  I've tried passing as parameters, using global variables, all to no avail.  The most common error is from 'delete', complaining that "The handle is not valid".

Many thanks in anticipation.
