Note that the height range parameter is a special case, flipping the value to make 0 appear at the bottom of the graph. Data often needs additional manipulation before it can be used for drawing. So what is it about Kibana that makes it a must-have tool for Elasticsearch? The aggregation of our data is not done by Kibana, but by the underlying elasticsearch.We can distinguish two types of aggregations: bucket and metric aggregations. When it comes to visualizing data Kibana is well suited for monitoring logs, application monitoring, and operational intelligence. Scaling is one of the most important, but somewhat tricky concepts in Vega. Adding "scale": "yscale" to both y and y2 parameter uses yscale scaler to convert count to screen coordinates (0 becomes 99, and 8000 - largest value in the source data - to becomes 0). Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs.
