I am very thankful for your typical very, very fast response ??
I’ve gone thru doc. of configuration option, and found the the default chart type is ,line’ chart for a combo chart. And learnt from you that each series has to be specify individually.
(and apologize that I am not good at coding)
Isn’t this chart_series call for an object value (that should be a JSON according to your FAQ page), have tried below combinations but not successful on getting a Combo (bar) chart
1.)
chart_series='{“type”:”bars”,”type”:”bars”}’
2.)
chart_series='{“type”:’bars’,”type”:’bars’}’
3)
chart_series='{0:”type”:”bars”,1:”type”:”bars”}’
thanks
