You can invert your image before plotting by "Edit>Invert"

White gives high values, black gives low values, unless you apply an
inverted LUT. You can mouseover the pixels and see the values in the
ImageJ status bar.

On the plot window, there is a "List" button that opens a text window
with all the plot values. Just save it as an xls file.

Best,
