Determine Axis Values based on Cursor Position

Hello,

When you have a time based chart, PowerBI displays the value of both X & Y axis values depending on the relative position of the cursor over the chart.

Refer image below, which shows the X-Axis value(September 2016) and Y-Axis values (0.79 & 1.13*).

Is there a DAX expression to dynamically identify & hold the X-Axis value (Sept2016) for use in other measures??

Is there a DAX expression to dynamically identify & hold the chart "title" (Period & Cumulative MPI) or similar, for use in other measures??

I'd like to use the "cursor selected X-axis value" in a dynamic lookup of comments, which would be displayed as part of the tool tip.  That way, as you move along the X-Axis and the cursor position changes, the cursor-X-Axis value also changes, updating the tool tip such that the comments shown is relative to the month the cursor is located over.

I'd appreciate any suggestions or recommendations you can provide.

Cheers.
