This example shows how to construct a simple, draggable point. It is produced by the following commands:

<div id="jxgbox" class="jxgbox" style="width:500px; height:200px; float:left; "></div>
<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('jxgbox', {originX: 200, originY: 100, unitX: 50, unitY: 50});
 var p = board.createElement('point',[1,1]);
</script>

The JavaScript code has to be placed AFTER the div element which will contain the construction. From now on, we will only show the JavaScript code.


Attributes of a point

Several attributes can be given to change the properties of a point.

var b2 = JXG.JSXGraph.initBoard('jxgbox2', {originX: 200, originY: 100, unitX: 50, unitY: 50});
var p = b2.createElement('point',[1,1], {name:'X',style:5});


Point styles

The property type of a point can attain the values 0..12. In this examples we use a for loop to create 13 points.

var b3 = JXG.JSXGraph.initBoard('jxgbox3', {originX: 40, originY: 100, unitX: 40, unitY: 40});
for (var i=0;i<13;i++) {
  var p = b3.createElement('point',[i,0], {name:'P_'+i, style:i});
}
