| Yes, there's some interface I'm not getting.
For all the variables for a graph there are, in this case, 12 values. I used strings like <xNameKey[]> to contain the 12 values.
All the months of the year on x axis, (n) tick values on y axis, and five different bars each with a separate value for each month, this is the value binding.
In the old java package I did a lot of iterating and parsing to generate the graph for the package.
I can't see how to fit the old into the new. On Dec 29, 2009, at 6:38 PM, Pascal Robert wrote: Le 09-12-29 à 21:31, Baiss Eric Magnusson a écrit : As the binding to <valueKey> to a Wonder ERPCategoryChart widget I had a

Am I missing something in the binding, my <item> array is a NSArray of inner class objects:
public class BarChartItem { // inner class public String[] xNameKey; public String[] yNameKey; public String nameKey; public Number[] valueKey; BarChartItem( String[] xNameKey, String[] yNameKey, String nameKey, Number[] valueKey ) { this.xNameKey = xNameKey; this.yNameKey = yNameKey; this.nameKey = nameKey; this.valueKey = valueKey; } } Bonus question: what does the <categoryKey> do? ---- Baiss Eric Magnusson http://www.CascadeWebDesign.com
