## Timelion 

Timelion is a time series data visualizer that enables you to combine totally independent data sources within a single visualization. It’s driven by a simple expression language you use to retrieve time series data, perform calculations to tease out the answers to complex questions and visualize the results. 

The following example uses Timelion to compare time-series data about the number of logs generated in the past hour, compared to the number of logs generated this hour. From this, you can compare trends and patterns in data at different periods of time. For IBM Cloud Private, this can be useful to see trends in the logs generated on a per-pod basis. For example, the chart in Figure 5-25 compares the total number of logs in the current hour compared with the previous hour and the chart in Figure 5-26 on page 187 compares the number of logs generated by the image-manager pods in the last hour.
