How to redraw SpaceTree

[Rach]

On my page web page, there's a dropdown and based on the selection I
want to "redraw" the SpaceTree. I'm resetting the "infovis" div but it
still doesn't work.

$("#infovis").html("");

The part doesn't work, is, when I reset the json object & call the
"init()" again, it does redraw the SpaceTree but it doesn't call
onCreateLabel method on which I've my customization.

What am I missing? Is there any method that basically can redraw the
SpaceTree just like it was initialized when first time it was created.

Wow...it's been 2 days no response! Anybody? :)

To simply my original description of the problem, add the following
HTML lines in the SpaceTree Example1.htm file.
...
<div style="text-align:center;"><a href="example1.js">See the Example
Code</a>

<p>

<input type="button" value="Redraw" id="redraw"
onclick="document.getElementById('infovis').innerHTML = '';init();" />

</p>

</div>

</div>

<div id="center-container">

<div id="infovis"></div>

</div>
...

What you'll see if you click on the "Redraw" button, the re-drawing
doesn't populate the labels. How to fix this?

Hi,

I'd recommend you to not delete the canvas or visualization containers.
Just delete all labels from the current visualization:

        for(var id in viz.fx.labels)
                viz.fx.disposeLabel(id);
                delete viz.fx.labels[id];
        }

and then *reuse* the same canvas instance to create a new instance of
a new visualization:

    viz = new ST(canvas, ...);
