I've been using goole charts for several months now and have had no
issues...after the recent deployment on December 7, 2011 my line and
combo charts are returning an error of " 'count' is null or not an
object ". I can not find any documentation as to what this is
referencing. Following is my link to a pop up window to display my
chart and after that is the chart code.
I'm using the 1 asp page with the generic chart code in it and passin
multiple variables through the URL. Sometimes it has 7 horizontal
columns if it is displaying days of the week and sometiems it has 12
Horizontal columns if it is displaying months of the year. So I tried
to design a versital chart for multiple uses so I only have to make
chages to one block of code.
Thanks in advance for any help, or anythign that can point me in the
right direction.
