Get the number of draw objects on a chart

[RJBen]

Looking at the DrawObjects for Developers, I'm confused.
Under the section" Get the number of draw objects on a chart

protected override void OnBarUpdate()
{
if (DrawObjects.Count == 3)
{
// Do something
}
}

If you're trying to get the number of draw objects on a chart, why is it set to 3?
How do you get the number of draw objects on a chart if you don't know how many are on the chart?

Hello RJBen,

Thank you for your post.

That condition does not state, "DrawObjects.Count is 3," nor does it set the Count equal to 3.
In C#, == is an equality operator (it checks for equality, it does not assign a value).

The condition asks "if DrawObjects.Count is 3, then do something".

DrawObjects.Count will return the number of objects in the DrawObjects collection.

Ahhh understood. Thanks Super Moderator Gaby! As long as we're on the subject, what would the syntax be to actually get the count?

Hello RJBen,

As per my previous response:

DrawObjects.Count will return the number of objects in the DrawObjects collection.
