 If you select **Mode indicator function (MIF)** together with **Display selected FRF** or **Display summation of all FRFs**, the chart is split in two. The MIF is shown on top and the FRF or the summation is shown below it.

 EDM adds peak or valley markers to the chart automatically, and a note below the display options tells you what to look for, for example //"The valleys indicate the natural frequencies"//.
