Hi Rodrigo,

You may use BaseChart.makeChart. Note that BaseChart.makeChart expect a file path name to store the image, not a URL path. If you are using a URL path, please use Server.MapPath to convert it to a file system path before passing the path to ChartDirector:

For example:

Call c.makeChart("c:\\aaa.png")

or

Call c.makeChart(Server.MapPath("\\tmpcharts\\aaa.png"))

Note that you must make sure the directory that stores the chart image exist. Also, please make sure the directory is readable and writable by the IIS anonymous user. By default, the anonymous user cannot write to any directory. You would need to configure your directory security to enable "everyone" to have read/write access so that IIS can store the image file in the directory.

Hope this can help.

Regards
Peter Kwan

thank you it works with configure  iis allow autentication "Anonimous" and  directory security to enable "everyone".
