This button displays a popup grid showing details for each of the loaded points, in this case only one

This shows the ident of the point, its name and the range of all the data available.

Double clicking on this field will cause the ‘First Point Date’ and ‘Last Point Date’ to be copied in to the date range on the chart. Clicking the refresh button after this action would cause the chart to be refreshed with all data for this point.

The ‘Show Plot’ tick box is a toggle which hides or displays the corresponding plot line (same action as clicking on the point name in the chart legend). The alarm levels tick box toggles the display of any configured alarm thresholds on the chart (e.g., Both “Show Plot” and “Show Alarm Levels” are ticked by default).
