yes it is possible to do a dual-axis line chart.  i have done this before with a time scale in the X-axis and a revenue/cost scale in Y-axis

@paul harland , Thnx for quick reply.

I am saying that create dual axis with using Bar chart with line chart.

 How is possible , pls explain us.

hi @Adarsh 

oh on the same element? No you cannot have a bar and a line together.

You can have multiple lines.

Ok,

Thanx for your response.

But i need such of solution to show lobby graph with using line and bar chart combination.

@Adarsh  It is not possible to combine line charts & bar charts in lobbies.
