How to use Syncfusion's SfChart with 2015⌶ ?

[PGilbert]

Hello, I would like to use 2015⌶ to populate a FastLineSeries of a SfChart from Syncfusion. This is the code that I use:

      sfChartBindDemo

 sfDir←'Syncfusion/4.5/'         ⍝ Location of the Syncfusion dll's
 ⎕USING←'Syncfusion.UI.Xaml.Charts,',sfDir,'Syncfusion.SfChart.WPF.dll'
 ⎕USING,←'System.Windows,WPF/PresentationFramework.dll' 'System'


 sfChart←⎕NEW SfChart

 sfChart.PrimaryAxis←⎕NEW NumericalAxis
 sfChart.PrimaryAxis.(Minimum Maximum)←0 10

 sfChart.SecondaryAxis←⎕NEW NumericalAxis
 sfChart.SecondaryAxis.(Minimum Maximum)←0 10

 fastLineSeries←⎕NEW FastLineSeries
 fastLineSeries.XBindingPath←⊂'C1'
 fastLineSeries.YBindingPath←⊂'C2'
 fastLineSeries.StrokeThickness←2

 mat←(⍳10),[1.5]2+0.5×⍳10
 ⎕EX'ns'
 ns←⎕NS¨10⍴⊂''
 ns.C1←mat[;1]
 ns.C2←mat[;2]
 options←2 2⍴'C1'Int32'C2'Int32
 fastLineSeries.ItemsSource←options(2015⌶)'ns'
 sfChart.Series.Add fastLineSeries

 win←⎕NEW Window
 win.Content←sfChart
 win.Show

However I am getting a DOMAIN ERROR when trying to set the binding with 2015⌶. What is it that I am doing wrong ?

Thanks in advance.

Can't help, but your message reminds me that I have an unresolved issue with Sparkline (gets the right number of data points, but shows all as zero values).

I'm wondering whether we should have a new Forum section just for SyncFusion (whose own documentation seems sometimes to be patchy).

Hello Dick, I would second you for a separate forum for the Syncfusion questions.

We have moved this to the (new) WPF & Syncfusion category.

Hi Pierre,

This is a gap in our implementation, and hopefully it'll get addressed soon. The problem is that we don't allow the matrix left argument when the variable to be bound is a vector of namespaces. A matrix is only allowed for a scalar namespace.

We'll get a fix out for this soon.

Best Regards,
John Daintree.

Hi John, with the latest fix, the example is working now. Thanks.

I am able to replace the following lines:

Code: Select all

ns←⎕NS¨10⍴⊂''
 ns.C1←mat[;1]
 ns.C2←mat[;2]

with:

Code: Select all

 ns←∆MatToNs mat

where ∆MatToNs is defined as:

Code: Select all

 ∆MatToNs←{ns←⎕NS¨(1⌷⍴⍵)⍴⊂''
     ⍎'ns.(',(∊' C'∘,¨⍕¨⍳2⌷⍴⍵),')←¨↓⍵ ⋄ ns'}

If there is a better way at doing this please let me know.

Regards,

Pierre Gilbert
