This can be used to manually comment the data on the chart.
To do this, click "Marker" and click on the chart where the marker is desired. This will add the marker to the chart. Next, type a memo in the memo text box and then click "Add". This will add the text to the memo list.
This process may be repeated to add multiple markers to the chart. The markers appear as green circles by default.
Double-clicking on a memo in the memo window will jump to the corresponding marker on the chart.
To remove markers, simply select the marker from the list in the Memo Window and click "Remove".
