Landscape or Portrait Orientation Report Parameter

I was wondering if there is a way to give the user the option to display a report in landscape or portrait orientation by using a report parameter. 
 
I found an article in DevShare which helped me figure out how to set the Master Page orientation from script: 
 
<a class='bbc_url' href='http://www.birt-exchange.org/org/devshare/designing-birt-reports/1246-set-master-page-properties-using-script/'>http://www.birt-exchange.org/org/devshare/designing-birt-reports/1246-set-master-page-properties-using-script/</a> 
 
I modified the code to use the report parameter value. 
in the Report's beforeFactory script: 
reportContext.getDesignHandle().findMasterPage("Simple MasterPage").orientation = params["reportOrientation"].value; 
 
How can I change the height and width of a chart on the report based on whether the user selected landscape or portrait orientation? It would be good if I could have the chart display as big as possible depending on the orientation selected, but still have the whole report print on one page only. 
 
Thank you!

Hi,

This is a script you can add to your report beforeFactory() method:

var vChart = this.getReportElement( "NewChart" );
var vOrientation = params["reportOrientation"].value;

reportContext.getDesignHandle().findMasterPage("Simple MasterPage").orientation = vOrientation;

if (vOrientation == "Landscape")
{
vChart.setWidth("8in");
vChart.setHeight("3in");
}
else {
vChart.setWidth("5in");
vChart.setHeight("3in");
}

Hope this helps!

Thank you very much! This resized the chart, but I noticed part of the footer in the Master Page is getting cut off when the user selects Portrait orientation. 
 
I have a grid in the footer of the master page that needs to change in width when the user selects Landscape or Portrait orientation. Does anyone know how I can change the width of a grid in the footer of the Master Page depending on whether the user selects Landscape or Portrait orientation?

Have you changed the width of the grid to a fixed value? If you leave the width of the grid to 100%, it will re-size automatically.

I resized the grid so that it would fit within the footer, then changed the width of the grid to 100%. That worked! Thank you!
