I’ve created an index line on a chart, but I can’t rank the results by the index value. What should I do?
You might have the x- and/or y-axis of the chart set to have linear scales. A performance index value can only be calculated from an index line plotted on a chart with logarithmic scales.
To change the chart axes, click Chart Settings from the chart toolbar, and change the Axis Settings to logarithmic for both axes. Add an index line to this chart. In the results list, you should now be able to rank by index value.
