Post From: Trend Lines move, when scaling in or out.

And we can produce a video right now if you want, showing numerous scenarios where Sierra Chart will not have this problem either. I have done something very similar to what you did with this other program, and did not see a problem.

The image you posted from this other program does not prove anything because it is not an exact duplication. There are so many variables involved here. You should recognize that. The bar spacing, the resolution of the chart, the actual endpoints, the relationship between the two of them, the scaling. And many more variables.

And more precisely it is not really about mapping a floating-point coordinate system used by the chart into an integer coordinate system used by the monitor. The main issue is that the coordinate system of the chart does not match the monitor.

If you see a line drift away from its anchor point, it only occurs at certain points as the scale is being changed. What you find is that it may move a couple of pixels off and then go back. All of this is completely natural.
