Real-time line-plot

P: 1
I want to be able to produce a line-graph on my home page (intranet), so that my colleagues could keep an eye on the progress of certain variable. There will be 17 color coded lines plotted against time 24/7 at 5 min intervals. I prefer something simple that runs inside my browser.

Thanks

Good for you. You'll have to write it yourself too. We only asisst with your code where we can.
The thing you want is probably an Applet. You'll also want to have a look at a JFreeChart.

If your colleages should be able to see some changing data you need a bit more
that just a browser: you need some form of a server running a service, i.e. some
data needs to be supplied in order to be able to view it.

May I suggest that, since you're probably using a LAN or similar, let go of that
entire browser idea and have a look a JRobin. It's a Java port of the well known
rrd toolset (Round Robin Database) that is able to collect data at certain time
intervals and it is able to display the data as well, in various formats.

JRobin and rrd are heavily used by those snmp folks and your application
resembles its particular use. You do have to do some coding yourself though.

kind regards,

Jos
