Is it possible to make the chart vanish completely?

Not sure what you mean but if you change the chart type to "line graph" and then change the line colour to the same colour as the background, then you essentially have a blank chart.

Hope this helps.

This is what I meant, but from the EA...

Hey Mate
I stumbled on your comment about arbitrage the other day and was wondering whether I could chew the fat on the topic.
