Similarly to Timelion, Time Series Visual Builder enables you to combine multiple aggregations and pipeline them to display complex data in a meaningful way. Currently bumping my head over the following. After entering our parameters, click on the 'play' button to generate the line chart visualization with all axes and labels automatically added. in this world.
