How do I create an OrgChart with all nodes collapsed when first displayed?

[gwiens]

I looked through the documentation and scanned this discussion group
looking for syntax help, but I have not found it.

My experiments with this include calling the method
collapse('ndx','collapsed') (where ndx is an integer). However, none
of my permutations has made any difference in the tree -- all nodes
still are created fully expanded.

Can I get an example of node creation which will produce a collapsed
node?

Or do I need to create the tree, then visit each node while calling
the collapse method on each?

Thanks

Hi.

I think that indeed the only way to make all the nodes collapsed is to run collapse on all the rows.

Best,

Could I get an example of how to use the "collapse" function and where
to place it in the sequence of creating an OrgChart?

Have a look at the playground at the org chart example: http://code.google.com/apis/ajax/playground/#org_chart

Modify the last line which draws the chart with:

  // Create and draw the visualization.
  var chart = new google.visualization.OrgChart(document.getElementById('visualization'));
  chart.draw(data, {allowHtml: true, allowCollapse: true});
  
  for (var i = 0; i < data.getNumberOfRows(); i++) {
    chart.collapse(i, true);
  }

Hope this helps,

Thanks for the example. However, I could not get nodes to present in
collapsed mode when I ran the modified playground code. I had tried
this before and thought I didn't understand the syntax or placing of
the for loop.

I do my testing using Chrome. However, I thought maybe another browser
was called for, so I also tried using IE. Same effect -- nodes all are
drawn in fully expanded mode.

Have you added the additional option flag {allowCollapse: true}?

This exact code in the playground worked for me on every browser I tried (Safari, Chrome and Firefox - all on mac).

I missed declaring the putting the "var chart = " before new
google.visualization.OrgChart... bit. Thanks -- it did indeed work.

This has saved me about three hours of works that otherwise would have frustrated me to no end.

Thank you so much Viz Kid. All the best,

Tim

Hi ,
I could show default all rows collapse nodes using above code.But the requirement is now to collpase upto 3 levels from bottom of hierarchy. in other words show hierarchy default as expanded to 3 levels only.I have tried above code by giving hard coding valued for row index,but it collapses the node vertically and not horizontally.
Any help will be greatly appreciated.?

Thanks,
Mandar
