The chart view is a time-series chart allowing you to visualise property values over time.
To zoom, click and drag a window on the chart canvas. To zoom back out again, double-click the canvas.
Under the cogwheel icon you can add multiple properties to the chart. We combined all numeric properties into a single Y-axis on the left. String or enumerated types are placed on the right Y-axis, to prevent them from interfering with the numeric values.
You can use the chart legend to toggle properties on and off - simply click the legend entry.
