4993    </script>
4994
4995  The CSV file is of the form
4996
4997    YYYYMMDD,A1,B1,C1
4998    YYYYMMDD,A2,B2,C2
4999
5000  If null is passed as the third parameter (series names), then the first line
5001  of the CSV file is assumed to contain names for each series.
5002
5003  If the 'errorBars' option is set in the constructor, the input should be of
5004  the form
5005
5006    YYYYMMDD,A1,sigmaA1,B1,sigmaB1,...
5007    YYYYMMDD,A2,sigmaA2,B2,sigmaB2,...
5008
5009  If the 'fractions' option is set, the input should be of the form:
5010
5011    YYYYMMDD,A1/B1,A2/B2,...
5012    YYYYMMDD,A1/B1,A2/B2,...
5013
5014  And error bars will be calculated automatically using a binomial distribution.
