Hi,

Since I've upgraded to Kibana 4.2.0 and Elasticsearch 2.0, some visualizations are black.

In this example, the Y-Axis metric is a Unique Count:

Thanks!

@davmrtl can you provide some more context so that we can reproduce? For example, do you find that you get black colors when you have many saved charts or lots of charts on a dashboard? Or does it seem to happen regardless of whether you have saved charts or not?

@stormpython This problem seems to occur randomly... No mater what is the visualization and how many metric are displayed... But sometimes, it displays well.

At this moment, I have:

  • 6 dashboards
  • 0 searches
  • 32 visualisations

The problem also happens on both creating visualizations on the fly and loading an existing one.

As I found this is bug with color mapping code. It runs out of colors if you have too much values in your indexes (like me). You can also randomly get all colors changed on page refresh. Or you can get several of your values all black on dashboard. It's a random issue and not very easy to reproduce.

I'm having the same issue for many visualizations. In addition to losing colors, line charts are losing the connecting lines when the problem is evident ("Show Connecting Lines" option is selected). This seems to impact multiple visualization types.

I'm having the same problem. Currently using 3 indexes, 4 dashboard and 42 visualisations.
I have noticed that the problem goes away after refreshing the field lists of your indices.

Known bug in 4.2 did you try 4.3?

The issue is still prevalent for me in 4.3 on both the Dashboard and Visualize tab. Some visualizations are completely black, while others are a mix of color and black. Line graphs are also still missing connecting lines when this happens.

Issue is happening to me for Kibana 4.3.0 ES 2.1.0, and it could be related to many key values (~200)

Just run into it as well... I don't presume there's any workaround for it? My dashboards are completely unusable due to this :(

@stormpython : just noticed that I'm seeing it consistently on all visualisations that use filters for sub-aggregations, e.g.:

(that's kibana 4.2)

@krisb78 yes, this is a flaw in the way we are implementing color generation. If too many colors are already assigned, the color library generates darker colors, where all of the darker colors appear black. We are working on a solution for this.

@krisb78, I guess the only workaround is to use color mapping
functionality for now. That's what I do with my dashboards.

@marcinkubica : Thanks, I'll look into color mapping!

…lors for every value in the color mapping object. Duplicating colors is ok. We simply want to map a generated color to a key without concern for whether it has already been used for another key.
