Hello,

I am currently working on a project to create a graph using an array. The main goal is to use a trend to form a curve from the array and then overwrite the curve once new data populates the array (basically a still graph that updates once new data comes in). I am assuming I should use a bit triggered buffer trend to accomplish this, could anyone explain how the trend request and trend transfer works? It would be greatly appreciated.
