A new % Comparative chart type is now available allowing you to compare the relative performance of two instruments.
To use the Comparative chart, add the second instrument, click the + button next to the instrument finder then search for the second instrument then select % Comparative as the Chart type.
The % Comparative chart shows values relative to the reference point bar. You can drag the reference bar to move the reference point on the x-axis. To use the left of the chart as the reference point, deselect the ruler on the toolbar – note that if you zoom, scroll or manipulate the x-axis, the reference point will change to the new left-hand side of the chart.
