I am assuming you do not want to execute the report again. The chart is
just an image (Except for SVG output), so you may be able to use various
methods described here:
http://stackoverflow.com/questions/170624/javascript-image-resize
to get a handle on the image use getElementById. To set the id for a
chart select the chart in the designer and then click on the bookmark
property in the properties editor. If you enter "testchart" The
following will be generated in the output html.
<img id="testchart"
src="/viewer/preview?__sessionId=20120427_174940_821&__imageid=custom834c87136f5c7e8361.png"
alt="" style=" width: 427.5pt; height: 262.5pt;display: block;"></img>
If you do not mind re-running the report you can put script in to set
the size:

John,
In your first post it looked like you were using the birt report tag
libraries. How are you calling the API from your JSP?

Jason,
sorry i should have specified how i was using everything. in my JSP i have the following:
<birt:report
id="blah"
reportDesign="smallChart.rptdesign"
isHostPage="false"
format="html"
height="250"
width="444">
</birt:report>
<script type="text/javascript">
function chartGrow(){
var x = document.getElementsByTagName("iframe");
x[0].style.height = 500 + "px";
x[0].style.width = 888 + "px";
}
</script>
so the HTML output is actually:
<div id="params_blah" style='display:none'>
</div>
<form id="form_blah" method="post"></form>
<script type="text/javascript">
function loadViewerblah(){
var formObj = document.getElementById( "form_blah" );
var paramContainer = document.getElementById("params_blah");
var oParams = paramContainer.getElementsByTagName('input');
if( oParams )
{
for( var i=0;i<oParams.length;i++ )
{
var param = document.createElement( "INPUT" );
param.type = "HIDDEN";
param.name= oParams[i].name;
param.value= oParams[i].value;
formObj.appendChild( param );
}
}
formObj.action = "/progname/preview?__report=smallChart.rptdesign&__masterpage=true&__format=html";
formObj.target = "blah";
formObj.submit( );
}
</script>
<iframe name="blah" frameborder="no" scrolling = "auto" style='height:250px;width:444px;' ></iframe>
<script type="text/javascript">loadViewerblah();</script>
<script type="text/javascript">
function chartGrow(){
var x = document.getElementsByTagName("iframe");
x[0].style.height = 500 + "px";
x[0].style.width = 888 + "px";
}
</script>
and i have a java class that is contructing the graph using the API. since i am not getting an <img> tag i feel like there is no ID name for me to grab a hold of.
thanks
john

John,
Where in that code are you calling your class that creates the chart? I
saw this but generates the chart using the normal engine:
"/progname/preview?__report=smallChart.rptdesign

Jason,
I have created a method in a java file. in the action class i call that method and build the graph passing in parameters, whch allows me to run it dynamically. it then saves it within my application as a .rptdesign. from there i can call it in the jsp as i mentioned above. here is a cleaned out version of how i am building the graph using the API:

When you create the chart and have the extended item handle just set the
bookmark on it like:
eih.setBookmark("\"MyChart\"");

Can you try and add reportContainer=div to your birt report tag?

Jason,
as i mentioned before i am now able to grab both the image and the frame. The frame enlarges perfectly, however i am still having a slight issue with the image...
here is the JS function i am using:
function chartGrow(){
var x = document.getElementById("blah");
x.style.width = 850+"px";
x.style.height = 400+"px";
var graph = document.getElementById("birtGraph");
graph.style.width = 600+"pt";
graph.style.height = "auto";
}
this function works to enlarge the image, however, it only enlarges the graphics, the bounds of the image still remain the same, so it cuts off. for example the actual image does enlarge, however, the image frame (not the iframe, but the bounds of the actual image itself) stays the same, and the image cuts off halfway through the graph so you only see a portion of it. I believe it is enlargeing the image, but the size of the image is already pre-definied from inside my java class when i use "eih.setHeight()" and "eih.setWidth()". Its hard to describe, but after altering the size, i only see half my image, and the other half is cut off, as if the graphic is too big for the image, so instead of a full pie, im getting a half circle, and my legend is cut off as well.
is there any way that i can alter the eih.setHeight/width size settings using javascript or am i only able to enlarge the actual graphic, but not the image?
thanks,
john

Is the chart type an image or svg. Try png. Look at the attached
example report and run it.
