Hi,
   First of all, I would like to thank all Wrox members for having this web site back again, we really missed it!!!. Thank you for your efforts.:D

   I have a problem where I have to draw a graph on an applet using some data in a text file. I would need to design an applet where I can display the graph and the data on the same applet. I had a hard time writing some code in Java to read the text file since I am novice in Java. Now, I am really stuck in how to take this data and graph it on an applet. I don't know which class to use for drawing the graph and how to scale it and draw the actual points or designing the applet itself. I would appreciate if someone can help me out by any suggestions or comments

 Thank you

Hi
To draw a graph in an Applet u need to use the Graphics class present in the AWT package. Graphics class drawRect(),drawString(),drawLine() methods can be used to draw a Graph in an applet. Reading a text file directly from an applet can't be done because Applet run in a sandbox and for security reasons Applet is not allowed to access the System resources.I guess if u are using Applets you must be creating a web based application which will run on Internt or a local intranet and this must involve a web server also if iam right.If this is the case i suggest you to write a JSP or a Servlet for this and let the applet communicate with the Server application and get the data u need.

hope this helps
