Take care that the getvalue function is overloaded by Scilab to silently
evaluate and chack the arguments that are given by expression based
variables defined in the Xcos context
Basing your bload dialog on a other function will breaks this behavior...

It is not a Scilab problem.
It is better to preserve the plotfr handle in the user_data gui, so even if
plotfr is cleared
it can be retreived.
Moreover I had improved a little your code to makemove more smooth (avoid clf
and udpdate the polyline and axes bounds

Yes, just enter your data in a matrix and set the undefined values to %nan

If you know the approximate size of the footer in number of bytes (assume N
greater than it) you can try to set the pointer N bytes before the end of file
using the
u=mopen(myfile);
mseek(-N,u,'end')
then read the rest with
mgetl(-1,u)

If the initial position of your sphere are randomly set, it can be

Defining a tlist with unnamed fields is indeed an idea which

You will find in attachment a modified version, merging your proposal

On
with a string column formatted as you want, you
may use a tlist

out = msprintf(%02d:%02d:%04.1f\n,h, mn ,s)
T=tlist([foo,data,time],X(:,1:2),out)
I hope it will help.
