The Plot Window provides line cuts through the ccd image.
The plot window is automatically opened at start up.
If it is closed or hidden, it may be brought back to the front by
selecting the tools option,
plot... sub-option from
the main menu.
The Plot window shows either a row or column cut of the image
corresponding to the current image cursor location. Clicking on a point
in the main display
window, in the zoom
window, or in the values
window relocates the location of the plot cut.
Row and column plots are selected by the buttons in the lower left of the window.
The stretch (range of values plotted) is adjusted by typing in the upper and lower limits into their respective boxes on the left side of the graph.
The extent of the row or column plotted can be adjusted by changing the limits beneath the graph. By default, the plot shows the entire row or column.
If you click on a point within the plot window,
the x and y coordinates of that point are displayed. This makes
it easy, e.g., to read the peak value of a curve. (Warning, the
displayed values are the x and y values of the point that you
clicked on, this is not necessarily the same as the value of the
pixel that is at the x coordinate that you clicked on.)
