Make crosshair appear when chart loaded?



i’m trying to make horizontal line with tooltip containing the last value,

i make it as a crosshair, but it appers only on long press.

can i just make it apper / disaper programaticlly to make it always visible?

i already checked this topic:

but still cant see the crosshair when the chart loads,

also, is it possible to put 2 crosshair’s on one chart?

thanks alot!
