<div>Hi, </div>
<div><br>
</div>
<div>I am trying to plot a set of data points (2D or 3D feature
points), where each points is marked by a different number (typically
the index of the vector) . </div>
<div> </div>
<div>More precisely, I am used to call plot2d this way:<b> </b></div>
<div><b><br>
</b></div>
<div><b>-->scf() ; plot2d(attrib_point(1,:), attrib_points(2,:) ,
style = -1) ;</b></div>
<div><b><br>
</b></div>
Which gives a plot where all points are marked by a '+' .
<div>Now instead of the '+', I would like to have each point to be
marked differently, ie by '1', '2', '3',... , ie their index in
the attrib_point(1,:) vector . </div>
<div><br>
</div>
<div>Any solution ? </div>
<div>Thanks in advance .</div>
<div><br>
</div>

can use cstring for that<br>

You can use xstring for that:<br>
<br>
2D example<br>
<br>
x=1:10;y=x^1.5;<br>
clf;plot(x,y,'+')<br>
for k=1:10,xstring(x(k),y(k),string(k)),end<br>
<br>
or more efficient if there are many points<br>
drawlater();for k=1:10,xstring(x(k),y(k),string(k)),end;drawnow()<br>
<br>
3D example, a little more complex due to 3d functions limitations<br>
<br>
x=1:10;y=x^1.5;z=x^2;<br>
clf;param3d(x,y,z)<br>
//replace lines by points<br>
e.mark_mode="on";e.mark_style=2;e.line_mode="off"<br>
//xstring do not yet handle the 3D coordinates<br>
drawlater();for
k=1:10,xstring(x(k),y(k),string(k)),e=gce();e.data(3)=z(k);end;drawnow()<br>
