[Scilab-users] Redrawing a maximized figure changes its original size and other problem

[P M]

Hi Federico,

Assuming that you ALWAYS want to have the figure at max screen size:

Question 1:

You can work with the screen width/height values to maximize the figure.

To get the screen values you can use:
- screenWidth =  getsystemmetrics('SM_CXSCREEN')
- screenHeight = getsystemmetrics('SM_CYSCREEN')

Your figureHeight may be some pixels less than the sceen Height, so that
the taskbar won't be covered.

With these values you can set the figure size using the figure properties.

Question 2:
Maximising a figure at my PC results in a full screen figure, with the
taskbar at the screen bottom beeing visible.

Having the correct figure size (see Question 1), you can set the figure
position by:
gcf().figure_position = .....



Other approach:

Instead of clearing the complete figure, you maybe only need to clear the
graph (entitiy).
If you have multiple graphs in one figure, the approach is similar, but you
need to pick the correct entity.

Assumption:  Only one graph within a single figure.

x = linspace(1,100,100);y = sin(x);
f = figure(101);f.background = -2;plot(x,y);a = gca();e = gce();p =
e.children();

--> Now maximize the figure manually or have it already a max screen size


p.data = [];            // clearing the data of the graph ... same as
a.children.children.data = []y = cos(x);             // simulating
new data p.data = [x; y]';       // replotting the graph with new data


Note:  The approach does not change the axis min/max values....so you maybe
need to tweak these parameters, depending on your data.


Good luck,
Philipp
