How can I add multiple symbols in a tradingview chart widget?

I'm using the tradingview widget with this code:

I would like to be able to add a second symbol to the widget:
"symbol": "BTCE:BTCUSD" So I can compare the two.

I know I can add a symbol manually after loading the widget, but is it possible to have a second symbol allready added when the widget first loads? if so how would I do this? Also can I set the y-axis to display "price" rather than "percentage" on first loading the widget with t symbols plotted?

thanks for helping
