drawlater - makes axes children invisible.

Calling Sequence

drawlater()

Description

This function can be used not to display immediatly onto the current figure the next created graphics objects - i.e. by calling high level functions such as plotting functions or setting properties to existant 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
  set("figure_style","new") // select entity based graphics
  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

  subplot(212)
  a=gca();
  drawlater // what will be present in this axes will be displayed later
  plot2d // draw these axes and children later...

  subplot(211) // Warning: we change the axes
  plot2d1 // default drawing mode

  draw(a) // ...axes only is visible providing you not redraw the window
  drawnow() // all is visible
