Hi Toby, Some extra info, but no answers:
Working Chart (11 markers): http://tinyurl.com/23egvqw Non-working Chart (12 markers): http://tinyurl.com/26sffn3 Chart API validation of non-working chart: http://tinyurl.com/29hk5pe Validation Response: Warning The Chart API request contains the following warnings: "The parameter 'chem=...' does not match the expected format (INTERNAL_REGEXPVALIDATOR_ERROR)." Besides confirming your results, I haven't played around with different CHEM parameter values to find a possible cause (besides the total number of markers). Good luck, Keith -- You received this message because you are subscribed to the Google Groups "Google Chart API" group. To post to this group, send email to google-chart-...@googlegroups.com.
