Hi,
Quite new to flex but think i am on the right track with
this. I have been getting a strange error and hope someone can help
me with it.
I am putting together a linechart which shows the number of
unique visitors on my site. It contains two datefields which the
user enters the start and end date.
I am receiving the xml data from my webservice which looks
like this
<data>
<result day="3/14/2008">
<visitors>347</visitors>
</result>
<result day="3/13/2008">
<visitors>389</visitors>
</result>
<result day="3/12/2008">
<visitors>276</visitors>
</result>
<result day="3/11/2008">
<visitors>461</visitors>
</result>
</data>
When i attempt to bind this as a string to my linechart i get
this error ""
ReferenceError: Error #1069:
Property visitors not found on String and there is no default
value.When i convert the string to XML i get no error but nothing
appears on my line chart.
My code is as follows:
