<p>
When a one-dimensional FITS is loaded, QFitsView displays that as a line plot.
The values are displayed along the y axis, the x axis either shows consecutive
numbers starting at one, or physical values if the WCS header keywords in the
FITS file are existing.
<p>
The following operations are available in 1D view:
<ul>
<li>
the current x and y values are displayed in the upper right when the mouse is moved
</li>
<li>
zooming into the plot is possible by dragging the mouse with the left button clicked
</li>
<li>
unzooming to show the complete FITS is done using the context menu, available by right-clicking into the plot
</li>
<li>
the plotting ranges can also be set using the entry fields in the upper toolbar
</li>
<li>
the plotting style (either continuous line or staircase) can be set from the context menu
</li>
<li>
line deblending can be done by pressing d-d, then g and/or l. The f key initiates the actual fitting. This is described in more detail in the <a href="fitting.html">fitting documentation</a>
</li>
</ul>
