Indicator lane disappears

[arnold.horvath]

Dear Support,
I am working on relatively complex indicator at least to my standards...
I am sure, I am doing something wrong, but so far I could not figure out what can cause the below undesired effect.
First suddenly the indicator lane disappers as I scroll through the screen and finally the whole screen becomes empty. pl.see attachment.
At a specific point the indicator values come back and everything is fine again.
I tried to look for extreme calculated values or lack of data, but without any success.
Can you please clarify what can cause these symptoms ? What should I check ?
Thank you,
Arnold

Arnold, thanks for the post - is there any log / trace issue seen in your files when this happens?

Do you work with any custom C# drawing in the overriden plot method here?

Hello Bertrand !

Thank you for the answer.
I have found the problem and it was my mistake of course.
I drew a line to "infinity" in a specific case.

Glad to hear you could resolve Arnold!
