I am trying to create a graph plugin for statusnet which would extract values from the database and generate a bar chart dynamically which would then be displayed on the plugin page. Any idea how to go about doing this? I tried using jpgraph but it keeps giving me a blank page. Also i tried generating the graph as a image file and then displaying the image on the plugin page but again, gives me a blank page. There are no error messages in the logs either! Would be great if someone could help me out here. Thanks!
