I'm trying to create dynamic charts as described in "Creating charts using Zoho Sheet API" but the returned chart doesn't show any data. (See attached) The command used was
http://sheet.zoho.com/zohochart.do?&charttype=LINE&chartdata=1,2,3,4,5,6,7,8,9 and should retrun a line chart with a diagonal line but no line is present. Am i doing something wrong in the code?
