  • Filter editing has gotten its own edit pane with much improved UI and options
  • Issue #296. Templating: Can now retrieve variable values from a non-default data source

  • Templating and url state sync has some issues that are not solved for this release, see Issue #772 for more details.

InfluxDB Breaking changes

  • To better support templating, fill(0) and group by time low limit some changes has been made to the editor and query model schema
  • Currently some of these changes are breaking
  • If you used custom condition filter you need to open the graph in edit mode, the editor will update the schema, and the queries should work again
  • If you used a raw query you need to remove the time filter and replace it with $timeFilter (this is done automatically when you switch from query editor to raw query, but old raw queries needs to updated)
  • If you used group by and later removed the group by the graph could break, open in editor and should correct it
  • InfluxDB annotation queries that used timeFilter should be updated to use $timeFilter syntax instead
  • Might write an upgrade tool to update dashboards automatically, but right now master (1.8) includes the above breaking changes

InfluxDB query editor enhancements

  • Issue #756. InfluxDB: Add option for fill(0) and fill(null), integrated help in editor for why this option is important when stacking series
  • Issue #743. InfluxDB: A group by time option for all queries in graph panel that supports a low limit for auto group by time, very important for stacking and fill(0)
  • The above to enhancements solves the problems associated with stacked bars and lines when points are missing, these issues are solved:
  • Issue #673. InfluxDB: stacked bars missing intermediate data points, unless lines also enabled
  • Issue #674. InfluxDB: stacked chart ignoring series without latest values
