<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wonder if anyone could suggest a solution to this problem?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I want to:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Create a figure. This remains fixed. This I can do.<o:p></o:p></p>
<p class="MsoNormal"> Create four axes within the figure. These remain fixed. This I can do.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> In each of the four axes plot two reference curves. These remain fixed. This I can do.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Repeatedly call a function A<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:36.0pt;text-indent:36.0pt">which calls an inner function B<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:72.0pt;text-indent:36.0pt">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many thanks in anticipation.<o:p></o:p></p>
