Clojurians Log v2

cljs vectors (created using [] syntax) and maps (created using {} syntax) are not the same as JS arrays and objects

so your data1 and data2 are created using CLJS vectors and maps and the chart components probably don't know how to read them

you can write JS arrays and objects using the #js reader tag, e.g.

(def data1
  #js [#js {:x (js/Date. 2005 0 1) :y 21}
       #js {:x (js/Date. 2006 0 1) :y 24}
       #js {:x (js/Date. 2007 0 1) :y 36}
       #js {:x (js/Date. 2008 0 1) :y 38}
       #js {:x (js/Date. 2009 0 1) :y 54}
       #js {:x (js/Date. 2010 0 1) :y 57}
       #js {:x (js/Date. 2011 0 1) :y 70}])

Thanks, It works. I also had to do similar to the CLJS vector of services:

($ Inject {:services #js [LineSeries, DateTime, Legend, Tooltip]})
