Flags disappear when there are more than 160 or so

Flags disappear when there are more than 160 or so

Postby mmainguy » Thu Aug 25, 2011 3:55 pm

We're using highstock with a "lot" of flags, but they seem to stop rendering after around 160-170. Is there some sort of limit?

format of each flag in data array of series is

{"x":1311634800000,"title":"A"}

Are you sure that it's not rendered at all? Maybe it's just data grouping fault? Try to zoom in a range where you know that should be a flag.

I'm having the same issue.

When there are more than 160 flags or so, I can see them when I zoom out to "all," but they disappear completely when I look at 1Y, or a different zoom level.

I've noticed that if the zoom level is to where at least one flag should not be visible, all of the flags become invisible.

Any ideas?

Thanks.

Actually, I'm seeing this issue with as few as 80 or so flags; so not really sure what's going on or where the threshold is.

As I told in my previous post - have you tried to disable dataGrouping for flag series? http://www.highcharts.com/stock/ref/#pl ... g--enabled

I am having the same issue. When I disable the dataGrouping then I can't do the click event or even see the flag text.

Well, could you set up a jsbin demo to show us exactly what's going on there?

Here's a jsbin:

Notice how the flags only appear when you click "all". They don't appear when you click "YTD" or 1Y, etc.
