How to merge Bar graph and Line Graph into the same panel

Hello,
I’m working on my first complex Graph using Grafana and influxdb.
thanks in advance for your support
I would like to display the Graph in 2 parts, one axe using bar graph (separate bar) with the electric consumption, one axe using lines with the electric cost.
I have created 3 queries to get electric consumption and created 3 transform Field, All is working well
Here the Graph that I’m able to display

I have exported the data in Excel to show what I would like, the axis is the same but cost are based on Lines (right Axe) and each electric consumption is displayed with a separate bar (left Axe).
