Re: JSMX cfchart

[Peter Boughton]

If it's a JPEG then you could just have an IMG tag, and change the SRC.

ie:
<img id="mychart" 
src="http://myserver.com/generate_chart.cfm/chart.jpg?params=1"/>

<select onchange="showGraph(this.value)">
<option value="1">Something</option>
<option value="2">Something Else</option>
<option value="3">Another Thing</option>
</select>

<script type="text/javascript">
function changeGraph(v)
{
 document.getElementById('mychart').src= 
'/generate_chart.cfm/chart.jpg?params='+v;
}
</script>

Something along the lines of that, with generate_chart having nothing except a 
cfchart tag (and any related processing of parameters).

That make sense?
