 Manually doing a full update with extra parameters |

Hi
I have a chart with some overlays on it for selecting which lines to show (as well as the standard zooming/panning stuff).
When someone modifies the line selection, I want to recreate the graph, keeping the current pan/zoom etc, but with the new line selection.
I assumed I could do it by doing something along these lines -
function updateLines(line1,line2,line3){
var viewer = JsChartViewer.get('bob');
viewer.setCustomAttr("line1",line1);
viewer.setCustomAttr("line2",line2);
viewer.setCustomAttr("line3",line3);
viewer.partialUpdate();
}
Only I am not doing a partial update, it is a full update (full HTML page is returned, plus image), so trying to use partialUpdate returns an "Error 800 - Partial update returns invalid data". But there doesn't seem to be an equivalent 'fullUpdate()' function - can you tell me what I need to be doing here instead?
Thanks very much

Hi Jay,
The ChartDirector full update is designed to work even if your browser does not support Javascript. So there is no ChartDirector Javascript method does triggers a full update.
The full update is intended to be a fall back mechanism so that a web page can continue to work even if the browser does not support Javascript, or if the browser is a very old browser that supports only a subset of modern Javascript functions. Of course, you can use full update even if the browser fully suppports modern Javascript.
To perform a full update, the user can just press the submit button to perform a normal form submit. You can also use Javascript code to emulate a form submit. For example:
//submit the first form in your web page
document.forms[0].submit();
Hope this can help.
Regards
