This is a simple example, how RMChart works on a web server. Clicking Show invokes a cgi-exe, which calls RMC_CreateChart() with nExportOnly=TRUE. After calling RMC_Addregion() and RMC_AddGridlessSeries(), a temporary file name is created and RMC_Draw2File() is called, passing this file name as second parameter. The CGI creates a html-document with "img src=" set to the file's name and sents the html-page to the browser.
