Draw same trendline onto different graphs

[jplorans]

Hi there,

For a while, i've been looking for the way to draw a line (anyone) reflecting onto my other graphs

For the same pairs, I work on different time frames and graphs (each window equal one time frame) and i guess i'm not the only one to process like this, and i'd like to draw one line only once and not on all graphs.

Does anyone can help on this ?

Tks
