Hi

I found this
Code:
    // set a property of the Marker object
    Procedure Set MarkerProperty Handle hPrivateProperty Handle hComProperty Variant vValue
        Boolean bApplies
        Get DoesPropertyApplyToSeriesStyle hPrivateProperty to bApplies
        If (bApplies) Begin
            Set SigCJProperty hPrivateProperty hComProperty (Private_phoChartMarker(Self)) to vValue
        End   
    End_Procedure


    // Returns True if the passed property is registered to the specified series style
    Function DoesPropertyApplyToSeriesStyle Integer iPrivateProperty Returns Boolean
        tdPropertiesStyleLink[] taPropertiesStyleLink       
        Integer iSearchIndex iStyle
        
        Get Private_ptaPropertiesStyleLink to taPropertiesStyleLink
        // Search the struct array for the given property
        Get FindPropertyInStruct iPrivateProperty taPropertiesStyleLink to iSearchIndex
        // if we can not find the property then nor can we find the style against that property so return false
        If (iSearchIndex=-1) Begin
            Function_Return False
        End
        Else Begin
            Get Private_peSeriesStyle to iStyle
            // search the array of styles linked to that property for that specified in Private_peSeriesStyle
            Move (SearchArray(iStyle, taPropertiesStyleLink[iSearchIndex].iaStyles)) to iSearchIndex
        End
        // return true if found
        Function_Return (If(iSearchIndex<>-1,True,False))
    End_Function
