Why plot line is not visible (hidden, not displayed), but value shown in Databox ?

[ttodua]

I am facing a problem: plot is being correctly calculated (correct value) also shown in databox for each bar (when mouseover), however the graph is empty:




plot color is also ok... what could be the issue?

Hello TazoTodua,

Thanks for your post.

Are you using OnRender() in your code and if so have you included base.OnRender() ?

[ttodua]

many thanks. actually, i've seen that people use OnRender (without using base.OnRender) , and that shouldnt be a problem... However it was strange, i am now on different location and can't confirm if still happens...

Hello TazoTodua,

Thanks for your reply.

The OnRender() help guide offers this tip:

"If you are using standard Plots along with custom rendering from an indicator or strategy, you will need to ensure to call the base.OnRender() method for those plots to display."
