drawlater

Description

This function can be used not to display immediately onto the current figure the next created graphics objects - i.e. by calling high level functions such as plotting functions or setting properties to existent objects. The immediate_drawing property of the current figure is set to 'off' in order to postpon the next drawings.

It can specially be used with the drawnow function.

To enable back the immediate_drawing for the current figure, you can use drawnow function.

Warning : note that between drawlater and drawnow calls, the current figure may have changed. Therefore, this must be used carefully.

Examples

//Example :  one axes / one figure
drawlater();
xfarc(.25,.55,.1,.15,0,64*360);
xfarc(.55,.55,.1,.15,0,64*360);
xfrect(.3,.8,.3,.2);
xfrect(.2,.7,.5,.2);
xfrect(.32,.78,.1,.1);
xfrect(.44,.78,.14,.1);
xfrect(-.2,.4,1.5,.8);
xstring(0.33,.9,"A Scilab Car");
a=get("current_axes");
a.children(1).font_size=4;
a.children(1).font_style=4;
a.children(1).background=5;
a.children(3).background=8;
a.children(4).background=8;
a.children(5).background=17;
a.children(6).background=17;
a.children(7).background=25;
a.children(8).background=25;
xclick();
drawnow();

//Example 2:: two axes / one figure
clf
subplot(211)
drawlater    // what will be present in this axes will be displayed later
plot2d       // nothing is displayed => feeds the graphical buffer
subplot(212)
plot3d
drawnow      // the graphical buffer is flushed: all its contents become visible
