Anything in Java like MSChart

I wrote a VB app that uses MSChart to graph collected ping times over a 24 hour period. The app displays raw and graphical data for up to 10 devices along the path from point A to point B.

Now my director wants to put the functionality in a web page. I'm looking at a number of approaches. The data is currently collected via a script running on one of our Tandem systems and downloaded to an NT server where it eventually ends up in an Access database.

Since we have web servers on several of the Tandems, it makes sense to keep the data there and load it into an SQL table. Java script also makes more sense than VB script because some users may be running Netscape rather than IE.

One big deciding factor regarding the Tandem approach is whether I can recreate the graphs using Java. I have done a little searching in the web but have not found anything that meets my needs. Does anyone know of any packages/tools that I may be able to use.

FWIW, this is going to be my first Java app. I have a strong C/C++ background, so I know I can pick up Java quickly enough. If anyone knows that I am going to have problems with the graphing, let me know before I get too far into this.

you'll have to do it with the 2D graphics objects, and draw the lines yourself. it's not the ideal, but it'l work.

Just include java.awt.* in your applet

and you can use the graphics objects

you'll have to do everyting else (calculating endpoints, etc.) by hand, but the actual drawing of the lines can be done with the graphics tools
