For the chart simply right click the instrument and from the popup select chart. edit - on reviewing your pic vs mine you look to be in chart mode rather than screener mode, I don't believe you can do as suggested in that mode. if you need to pull charts from a screener start here https://www.tradingview.com/screener/ and not from the screener at the bottom of a chart page, hope that makes sense.
For size of font, as can be seen from my screenshot and as a bit of a magoo myself, I have set the browser zoom to 125% looks ok to me at that.
But you do obviously lose more info off the end the larger the zoom, but easy to scroll left/right to see it. I have T2W set at 150%
Errrr... ! Baffled - modes??! I'll search on that.
Presumably you can switch between modes.
I know that if you Google TradingView Screener you get one where you can't select 5 minute, 15 minute etc columns. Pay, they say for sub one day.
CTRL-scroll works in your mode, too. It's just for the odd number or word which is illegible so that will do.
