I have to create graphswithin lotus notes that has to work over the web. One problem though , they have to drill down into other graphs until you reach document level. for example , if I view a graph of sales figures by continent , I must be able to click on particular continent to view the breakdown of that continents sales etc...

I am clueless as to where to begin. I am not sure how to even begin coding graphs of this nature.

If I had to do this, I'd scratch my head first, to find the following thoughts:
- don't think graphs first, think functionality
- there are two things important: getting the data, and processing it
- assuming that real-time data isn't a requirement, you can extract data from Domino using XML and process it remotely using anything that understands XML (fast but bulky)
- of course you can make a connection to the Domino-server using Java, to extract the data you need (slower but more compact)
- to do exactly what you want, i.e. the clicking on graphs to inspect data in more detail, I would go for Java, either in an applet if the browser is required or a separate Java program
- there are many classes in Java available to produce graphs

Does this shed some light on you problem?

Where do the graphs come from?
Are they images stored in NotesDocuments?
Are they created on the fly by some special tool?

Possibly you can make a Flash movie to present the graphs, it should be easier than a pure DHTML solution. Here is a page that shows how to use Flash for showing an Access database contents: http://www.15seconds.com/issue/010605.htm
And at http://www.proposion.com/site/proposion.nsf/pages/N2N there is a tool for interfacing a .Net app to a Notes Database. There is a free trial but the registered version costs 1400 usd!!

Have you guys ever checked this.. http://www.thebrain.com

It has more of drill down navigation.. but not sure if that will work here.

For graphing solutions I prefer java applet which is more controllable and of consistent behaviour

Hi Everyone...

Thanks for all your comments , I really appreciate the help. I was also pondering the Java appet route , but the problem with that solution is if the person does not have Java Virtual Machine , the applet will just display as an image instead of what the Applet is trying to generate.

I am going to start looking today at code to generate the graphs within Java. If anyone has examples of Java code that generates graphs within Lotus Notes , Please can they help me by posting it or emailing it to the following address : PParuman@scs.co.za

Thanks

There are few techniques to achieve the results without java applet.. but I still bet java applet is the best way to go..JVM is browser built in, you don't have to worry if they have jvm or not. It will prompt them to download like plugin does.

The following techniques are also not that bad.. give it a try

Java Servlets are also a possibility, although the interactive part will be a lot more difficult.

Graphs are the easiest to handle using Excel. We always prefer that. You can see graphs and charts in excel and record a macro. Converting a macro to lotusscript is child's play

One major requirement of the asker is that he wants the graph to be interactive. Excel is good for generating static graphs. Drill downs will be a remote possibility with Excel.

using Crystal reports and generating from there is the best bet as per I know.

Hi everyone...

Thanks for all your posting ... a friend of mine found a Lotus Notes Database with the ability to generate graphs that drill down into other graphs , which is exactly what we were looking for. I have not seen the database yet , nor have I played with the code . I saw a brief demo from him on his machine of how the graphs work.

I am still exploring the Java route just incase the database he has does not work as nicely as we originally thought. Thanks for the posting og JFree Ranjeet , There is a wealth of info on that site.

I also thought about going the crystal reports way but unfortunately not all of our clients can afford crystal reports . Excel was also an option but like it was mentioned , the drill down capabilities are not that great.

I will keep you posted on any positive developments .

Thanks everyone.
