ruby on rails - How show two lines on map using gmaps4rails? -

i'm developing rails app, use google maps , paint car routes.

i use gmaps4rails gem drawling line on map,

so, have plan car ( array of coordinates car route plan ) , report car ( array of coordinates car route drove ).

so, have arrays of coordinates - plan , report, example random points :

@plan   = [ [12.124, 12,34253], [11.124, 12,34253], ... [8.124, 5.344] ] @report = [ [12.224, 12,64253], [10.124, 12,34253], ... [9.124, 6.345] ] 

i know how draw 1 line on map, example view 'plan' line on map:

%div.container   %div.panel.panel-default.col-sm-9     %div.panel-body.row       #map.col-sm-12  :javascript   handler = gmaps.build('google');   handler.buildmap({ provider: {}, internal: {id: 'map'}}, function(){     polyline = #{raw @plan.to_json}      handler.addpolyline(polyline); // , not addpolylines     handler.bounds.extend(polyline[0]);     handler.bounds.extend(polyline[ polyline.length - 1]);     handler.fitmaptobounds();   }); 

but need draw 'plan' line , 'report' line on same map. how can draw 2 lines different colors on same map?

thanks kindly.

there error in code, gmaps4rails expects array of objects providing lat , lng properties. transformation quite easy though.

concerning options, can pass them second argument. source code meant clear.

anyway, here working plunkr data
