Some of the new features added to Release 4.3d of RainPro are:

• High-colour support. Allows you to use hex strings such as chSet ('colour' '#9DC806,#78598D') (lime and mauve) wherever a colour name is normally given.
• Key frames – the Key Box property gives you complete control over key position and layout
• Page labels – the Page Label property is a convenient place to label the current values for any hidden dimensions
• Data Window – Window property simplifies the plotting of timeseries with switchover dates (actual/forecast)
• chBar – accepts ‘Stacked’ style as synonym for ‘relative,cbar’.

Other capabilities included for the first time in Release 4.4 are:

• Rain now substitutes solid ‘pastel’ colours for the first 7 patterns, mixing in an appropriate proportion of white; this looks a little better on high-colour monitors and compresses much better to keep the image size as small as possible.
• Multiple box-whisker plots for datasets with 2 category axes. As seen at APL99!
• Custom repeat patterns for dashed lines. Better (and faster) rendering of dashed lines where the repeat pattern is quite long compared to the interval between data points.
• Angled X-axis labels
• Vector graphics support for IE5 including drill-down and hot-links from any text. Vector support for non-Microsoft environments with a freely-available Java applet.
• Automatic trellis generation for small multiples and piecharts
• Support for custom fill patterns and custom markers
• Polar charts added as a standard chart type.

There are numerous other small improvements and bug fixes – check the Release variable in the RainPro workspace for full details.Viewer support for data and caption hotspots is now included in the APL+Win implementation; the viewer now shows data hints and tracks the (x,y) cursor on the chart region.
