Hi jennis,

ChartDirector does not need a directory to store the graph images. It can stream the image directly to the browser, or it may store the image in memory.

For example, in the "Simple Bar Chart" sample code, the chart is streamed directly to the browser, like:

<IMG SRC="simplebar.asp">

However, if you for some reasons want to store the chart image in the hard disk, you may use either BaseChart.makeChart or BaseChart.makeTmpFile. For example:

'Save the chart as a temporary file in Server.MapPath("/tmpcharts"). Please make sure
'the web server anonymous user has read/write access to that directory
filename = c.makeTmpFile(Server.MapPath("/tmpcharts"))

Now you can use the temporary file in your image tag:

<IMG SRC="/tmpcharts/<%=filename%>">

Hope this can help.

Regards
Peter Kwan
