  • [Lens] Support small multiples / facet / trellis for XY and Partition charts kibana#72063
• TSVB visualization doesn’t show negative values in UI. But the lens shows both negative and positive values. (This will be fixed in 8.8)
  • The chart do not render negative values elastic-charts#135

@rajvi-elastic , I do not fully understand the issue

"Splitting a chart into multiple smaller charts by a breakdown dimension is not supported in lens"

Does it lead to user seeing less amount of data after lens migration compared to the old visualisation ?

[agithomas]

Can you please share share the snippet of the screenshot displaying the impact of the panel data before and after lens migration ?

@agithomas , splitting chart functionality splits the visualization into multiple charts based on the provided field.

For example, below is the donut chart which shows user total count of records based on log.level.

Now if user wants to have this visualization for each datastream then he can split this chart into multiple using split chart functionality. Below is the visualization which splits the chart into multiple charts based on datastream.dataset field. So that user can have individual charts for each datastream which shows you total count of records based on log.level.

In our case, user won't see less amount of data or panel won't be affected even if we will remove the split chart functionality.

In the below panel (from which we have removed the split chart layer), event.dataset: activemq.audit filter is applied at the top level and then the entire visualization is also splitted based on the same filter. User won't see multiple charts in this case because of the top level filter. Hence, removing split chart functionality won't affect the functionality in this particular case.

Please find the below screenshot before migration (with split chart functionality and without split chart functionality)

The below screenshot is after migration without split chart functionality in lens:

In all of the three cases you will find the same count (3042).
