TSVB should use "histogram:maxBars" and "histogram:barTarget" settings for auto instead of a default 100 buckets #83628

alexwizp · 2020-11-18T12:12:41Z

Summary

This PR adds an additional Level of detail option for TSVB on the Time Series tab

The mechanism for obtaining the maximum value of buckets has also been changed. Instead of a hard-coded value of 100 buckets, now we take this value from the uiSettings by reading:

histogram:maxBars - max value for Max Bars input control
histogram:barTarget - default values for Max Bars input control

src/plugins/vis_type_timeseries/server/lib/vis_data/helpers/calculate_auto.js was removed. We reused the same code from data plugin

In this first round of comments I'm mostly commenting on the behavior. Here's what I noticed:

I think it would be save to increase the histogram limit well past 100 by default. Why not set it as high as 65k, which is the limit in ES for now?
Similar to the issues we saw with auto histograms for numbers, it's confusing that the slider doesn't actually change anything automatically. What we decided for Lens was that an unlabeled slider with 5 "steps" is a pretty good way of doing this
I'd like to tweak the form design even more, maybe we can use the idea of the "granularity" slider that Lens has?

src/plugins/vis_type_timeseries/server/lib/vis_data/helpers/get_bucket_size.js


-  return calculateAuto.near(100, duration).asSeconds();
+  return calcAutoIntervalLessThan(maxBars, timerange).asSeconds();


Okay so if I understand correctly this is the core part of the change, previously auto was hardcoded to 100, and now it's up to 100?

Yes that true. Now we read histogram:maxBars configuration property as a limit value. The user can change it if necessary.

alexwizp · 2020-11-20T12:33:53Z

@timroes @wylieconlon Today I tried various options for making this functionality obvious to users. What do you think about next option:

regardless of the histogram:maxBars value in the configuration, we will work with a percentage representation. In this case, a step of 10% of the histogram:maxBars value looks like a good solution from the UI perspective.

timroes · 2020-11-23T09:57:31Z

@alexwizp I like linking this up to the existing advanced settings. I also support Wylie's ask here for control of the level of detail. On the specific UI: I guess I'd not put a percentage on this slider, since it might cause confusion again: "What does 100% mean?" "So 50% will always be half of the 100%?" (which due to rounding it might not afaik).

I guess I would just label the two sides of the slider "Coarse" and "Finest" and don't give the actual values within a label in the UI.

I'm really liking the direction of this improvement! I've left a few more comments about the behavior and labeling, but I think I don't need to do another code review to approve the direction.

Before merging, please make sure the title and description are appropriate to be put directly into the release notes: https://www.elastic.co/guide/en/kibana/7.10/release-notes-7.10.0.html

This includes the checklist!

src/plugins/vis_type_timeseries/public/application/components/index_pattern.js

+                      isEntireTimeRangeActive(model, isTimeSeries) ||
+                      !(model[intervalName] === AUTO_INTERVAL || !model[intervalName])
+                    }
+                    min={0}


This value is definitely wrong because it will never generate data. I think a value of 1 is probably too low as well. What do you think about 10?

@wylieconlon I needed it earlier to correctly mark the scale from 0 to 100 with a step of 10. When entering a number other than 0, the scale would be shifted. I handle that case here:

Let's create a constant to make it a little obvious

Unfortunately even without a scale I cannot set1as a min value cause the max - min value must be a multiple of the step property, otherwise I see an error. Looks like a problem with EUI component.

Also I'm not sure that 10 is a good default value for this property. I think for some cases 1 value can be useful and allows to emulate "Entire timerange mode" which we have on other tabs in TSVB. Please keep in mind that to see data for that case you should set
