Lines drawn from an indicator vanish

[mithnadril]

When I draw a line from an indicator, the line does not always appear, depending on the size of the window or the time of the bar at the left border or the scaling of the chart. When I change the horizontal scale using ctrl-left arrow or ctrl-right arrow the line can disappear and reappear on the next zoom step.

The blue line in the attached images has been drawn manually, it does not show that behavior.

What are the correct parameters for the DrawLine function?


The attached indicator has been simplified to just show the problem.

mithnadril, there are known limitations in the rendering engine for objects with 2 or more anchor points, which would include the line. Are you sure you using the exact same anchors for your comparison testing?

Enhancements in this area are planned for our next major platform update.

Thank you for the quick response.

The anchor points were not the same, I just wanted to try if this is correlated with the visibility of the anchor points.

So I will modify the code to use a custom plot function.
