Click the Data source drop-down menu and select a data source. Each transformation allows you to add one new field. Take, for example, a query on a simple time series metric, `node_cpu_seconds_total`. Even for one machine with one CPU, this query will return many dimensions, for all CPU modes (user, system, iowait, nice, etc). In the following example, two queries return table data. Is there a method to do this in Grafana/InfluxDB? By default, Grafana dynamically calculates the width of an axis. The conditions are applied on a selected field.
