Stacked series become inverted after update

[eolsson]

1. Open http://jsfiddle.net/TheEvilHammer/MqJSR/7/
2. Wait 5 seconds for the timer to add data points

Result: The areas are now inverted and goes below the x axis.
Expected: The stacks to build up instead of down.

Note: This does not happen when removing stacking: 'normal'

When disabling the navigator the bug doesn't happen

Any update on this? This is a showstopper for us because it renders charts pretty much unusable.

I'll get back to this once 2.3 is out (one of these days)

Any updates now that Highcharts 2.3 is out?

[TorsteinHonsi]

I'm sorry, we still have this issue on top priority. I'm going away the
next week so there won't be much time for developing the next two weeks,
but I'll get at it as soon as possible.

Hi again, I couldn't get peace over this so I hacked away for two hours at this well-hidden bug. Finally tracked it down to the afterExtremes event that triggered a chart.redraw inside another chart.redraw, causing recursion because series were still marked dirty. Hope the fix helps, and doesn't cause other issues related to this very sensitive part of the Highstock logic.

Fantastic! Thank you very much for looking into this. Do you know when the next point release of Highstock will be?

[TorsteinHonsi]

Not exactly, but we typically have cycles of one month. Until then, I
recommend that you grab the diff, apply it to the current stable version of
highstock.src.js and compile it online at the Closure Compiler.

I don't know if manually patching the code is going to work for us; we need an official Highstock release. It's been a couple weeks since your last post, do you have a better idea as to when the next release will be? This is a high priority bug for us and we'd like to upgrade Highstock as our dev cycle is coming to an end very soon.

[TorsteinHonsi]

We're in the middle of some heavy refactoring of data labels now, but when
we've finished that and a couplye of other issues, we'll start testing for
a new release. It can be expected this week or the next.

Fantastic, thank you for the update.

I've been doing some testing with this patch and I don't know if the issue is completely fixed. I took the source from 1.2.2, applied the patch manually, ran it through Google's Closure Compiler, and deployed to my webapp. The original issue (where all series were inverted) has been fixed, but I'm still seeing weirdness where one series is inverted, plus there will be empty space where a series is missing, plus weird rendering problems.

I have also been able to easily repro this problem with the very latest version of highstock.src.js, so it's not an issue of me messing up the manual patching. Unlike the original fiddle I posted, it takes several updates (up to a few minutes' worth) to trigger this new issue.

Here's a jsfiddle that repros the issue within a few seconds: http://jsfiddle.net/TheEvilHammer/hywbV/11/show/

This fiddle is pointing to the most recent copy of highstock.src.js in github. How soon do you think you could have a fix for this?

[TorsteinHonsi]

Thanks for reporting, I've logged this new bug at
#1259. Will look
at it as soon as possible.

Excellent, thank you.
