Hi:

        I am testing CD 5.1  (using ABL from Progress software) and i need to get the xLabel value from a graph bar when i click to that bar and assign this to a variable.

Right now i can display the xLabel and the Value in the screen (Usin ChartViewer),   When i click in a bar,   the event triggers this procedure and  I can get the values ​​of the variables shown. . even the imagemap as text.

DEFINE INPUT-OUTPUT PARAMETER p-hotSpot AS COM-HANDLE NO-UNDO.
DEFINE INPUT-OUTPUT PARAMETER p-Button   AS INTEGER    NO-UNDO.
DEFINE INPUT-OUTPUT PARAMETER p-Shift      AS INTEGER    NO-UNDO.
DEFINE INPUT-OUTPUT PARAMETER p-X          AS DECIMAL    NO-UNDO.
DEFINE INPUT-OUTPUT PARAMETER p-Y          AS DECIMAL    NO-UNDO.

MESSAGE chGrafica:chartviewer:ImageMap().
MESSAGE "p-hotSpot " + STRING(p-hotSpot) + ", p-Button " + STRING(p-Button) + " p-Shift " + STRING(p-Shift) + " p-X " + STRING(p-X) + " p-Y " + STRING(p-Y).

END PROCEDURE.

Is there any way to get the xLabel Value?

Thanks.

Hi Javier,

The xLabel and value can be retrieved from the hotSpot Collection using "xLabel" and "value" as keys.

I am not familiar with ABL. In VB, the syntax would be like:

myLabel = hotSpot.Item("xLabel")
myValue = hotSpot.Item("value")

or you may use the simplified form:

myLabel = hotSpot("xLabel")
myValue = hotSpot("value")

Hope this can help.

It works !,    I was two days looking for the answer.  It would be nice to include this in the user guide.

Hi Javier,

The documentation is at:

http://www.advsofteng.com/doc/cdcom.htm#ChartViewer.ClickHotSpot.htm

I realize the above documentation mentions that the hotSpot parameter is a "VB Collection", without elaborating what is a "VB Collection". This may be difficult to understand for developers usng other programming langauges. We will include clarification of what is a VB Collection in future editions of the documentation.

And then I must thank you very much for confirming that it works.

Hi Peter.


         Although i remember that a "VB Collection" is equivalent to a Record,  The programming lenguaje i use does not accept the intruccion:

variable = hotspot("value")

   Because this,  i  was testing and looking for a property to get the value, the one i do not found.

The programming lenguaje i use accept only the property "item" wich you told me and is not documented.

variable = hotspot:item("value").

I am going to continue  testing the product and i tell you about the results.


Thanks
