Multiple Charts on a single page

[Markus]

I am attempting to return multiple charts on a single page. What I get
is the first chart being returned and none of the others. I am using
OWC11 and the charts returned need to be generated on the fly based on
filter data...so I can't save charts on the server as gifs and then
reference them.

Any help is appreciated
Thanks
Markus

chart2.ImageUrl = returnChartMonth("Month", "Areas", "areas")
chart3.ImageUrl = returnChartWeek("Week", "Total Units", "units")
chart4.ImageUrl = returnChartMonth("Month", "Total Units", "units")

You are probably overwriting something. I am doing something similar in
javascript,
I create separate objects for each chant space and data set.

Ultimately my load section looks like this:

for (nGraph = 0; nGraph < nGraphs; nGraph++) {
sObject = "ChartSpace" + nGraph;
sData = "ChartData" + nGraph;
%>
<%=sObject%>.XMLData =
<%=sData%>.transformNode(xsl.documentElement);
<%
}
%>
