Re: dynamic image generation

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

I ended up buying a product called RChart (homepage:
<http://www.java4less.com/charts_e.htm>). It's a Java applet (can also be used
as a servlet and standalone I believe) that we store on the IFS; my CGI
program creates parameters for the applet to use on page load. Now that I'm
using it, I'm glad to be doing things this way rather than static image
generation. The applet allows for scrolling and zoom in/out, features I
believe our users will appreciate.

I did have a peek at Netcharts (homepage:
<http://www.visualmining.com/products/netcharts.html>) recommended by Michael
Skvarenina on the web400 list. It has a lot of features and chrome, and
operates in the same manner (Java applet). Just starting out, I could not
justify the price.

Rchart cost us $52 (Rchart Gold), including source. It has fewer chart types
and features, but the basics are there, and is flexible enough for our needs.
It's available for as little as $22 (slightly fewer features, binary only). A
demo download is availble.

Netcharts costs about $1400, didn't check if it was binary only or sourced
also, but it appears to be in the high end of applet charting.
