Fill area just like tradingview.com charts

[Jordanelis]

Hello guys. I have been searching a lot to fill the background of 2 lineseries in lightweight charts in an Angular project. It is very similar to this function from trading view charts.

fill(plot1=, plot2=, color=)

I added a candleseries with high and open the upperline and low and close the lower line but it is horrendous. Especially when you zoom in.

Can anyone provide a solution or some ideas how it could work?
