Some Examples of VML Graphics
Vector Markup Language (VML) is shipped with Internet Explorer 5 and is used extensively by the Office-2000 components to save graphic images (such as equations) in HTML format. VML is very similar in style to PostScript, so it is very simple to take the intermediate PostScript definition used by the RainPro charts and convert this to the VML format. The examples shown here are typical of many of the graphs I have used over the years.
Scalable Vector Graphics (SVG) - the new standard from the W3C
SVG is a logical progression from VML, and has the backing of the WorldWideWeb Consortium as well as a strong mention in Tim Berners-Lee's book "Weaving the Web". RainPro can generate SVG documents which you can view with the free SVG viewer from Adobe Systems and the sample pages have a selection of various chart styles.
The Same Charts Viewed with Java
VML is ideal if your users all have the latest Microsoft technology, but for other operating systems and older browsers, Java is a much more portable format. The Java applet used to view the charts may be freely downloaded from our site or you can refer your page back to the causeway site to ensure you always get the most recent copy.
The Gilling Climate Data with Graphical Drilldown
These charts are saved as .GIF images, so can be viewed in any browser. They illustrate the graphical drilldown capability built into the latest version of RainPro - all the hotspots are generated automatically by the software from the data values.
The Gilling Climate Data as VML
This is to give you a simple comparison of the image quality and download time of a set of VML charts as against the same charts rendered as images.
