Hello Friends,

Hope all are doing well.

I was seeking some guidance on open-source, stable, efficient and  
better library (plugin/gem) for generating chars and graphs in rails.

here i am looking for graphs/charts with multiple scale in a single  
axis. also i am having concerns for exporting charts in some of report  
like pdf or image etc.

Please let me your thoughts/experience/guidance on this.

Thanks,  
Piyush.
