Help:The chart can not been shown on the webpage sometimes

Post by btdan » Wed Jan 05, 2011 1:51 am

Hi,I am learning to program by use of JFreeChart.But Now I have a trobule, Can anyone be kind enough to help me?
The Chart picture on the webpage can not been seen sometimes in Internet Explore. When I set the Security Level to low in the Option of IE, the picture can been seen again. I don't know how to fix this problem.
The following is the releated code:
///////////// Code begin /////////////
String DNAidentify="";
for(int i=0;i<(maxnum<showNum?maxnum:showNum);i++)
DNAidentify=DNAidentify+up.gotDNAindenty(i)+"-";
//String chartViewer = up.getChartViewer(request, response);
String fileNameLine=BarChart.getChartViewer(session,new PrintWriter(out),370,230,DNAidentify);
String graphURLLine = request.getContextPath() + "/CreateBarChart?filename=" + fileNameLine;
////////////// Code end ////////////////////

I use the following code to refer it:

<img src=" <%= graphURLLine %>" border=0 usemap="#imageMap" >
