To do 2D plotting, have at least one table open and then open a plotter
with the
Tools - Plot 2D (Ctrl+P) command.

On the plotter window, choose which table you will be plotting with and
the rows you wish to plot. You can then choose which fields will be used
for the X and Y axes. Note that only "plottable" fields can be used; for
example, a String field could not be plotted. For fields that contain
array values of a fixed dimension, you can choose which "slice" of the
array you want to plot. Once the parameters have been chosen, there are
two ways to plot: overplot or clear and plot. Overplot will add the
given plot to any pre-existing plots whereas clear and plot will clear
any previous plots. Note that overplotting means that all plots will be
on the same scale, so you probably want to use similarly scaled data.
There are also formatting options for the plot image itself.

If there is a row filter on the table you are plotting (see
Browsing:Tasks:Filter Rows), you have the option to apply this filter
when plotting such that only rows that pass the filter are plotted.
To apply the filter, check the "Apply Current Filter" box.

Zooming can be accomplished by selecting the "Zoom" option in the
hand tool option box. The region to be zoomed in on is then selected
using the mouse on the plot canvas. This process can be repeated to
zoom in as far as desired. The zoomer uses a zoom "stack" such that it
remembers all the zoom levels and is thus able to go back and forth in
the stack. For example, once zoomed in you can zoom out one level
by clicking the "Out" button or in one level by clicking the "In"
button. Scrolling the mouse wheel will also move out and in in the
zoom stack. You can return to the topmost level by clicking the
"Base" button or by right-clicking on the canvas. Note that these
actions are only available when the Zoom tool is selected. Also
note that if another plot is added to the canvas, the zoomer is
reset.

Panning can be accomplished by selecting the "Pan" option in the
hand tool option box. The plot can then be panned by clicking
and dragging the canvas to the desired position. This process
can be repeated to pan as far as desired. To reset to the base
position, click the "Reset" button. Note that these actions are
only available when the Pan tool is selected. Also note that if
anothe rplot is added to the canvas, the panner is reset.

Selecting can be accomplished by selecting the "Select" option
in the hand tool option box. The region to be selected is then
slsected using the mouse on the plot canvas. Once a region has
been selected, the following actions may be performed on it:
- Locate: generates a list of all the rows that contain
points in the selected region. A window is displayed
containing this information with the row numbers sorted.
Displayed rows can then be highlighted in the browser by
selecting the row to highlight and then clicking the
"Highlight in Browser" button. The "Next" button can
be repeatedly clicked to move through the displayed rows.
- Clear: clears the selected region from the plot.
Note that these actions are only available when the Select tool
is selected. Also note that if another plot is added to the
canvas, the selected region is cleared.

To save the current plot as an image, first select the image format you
wish to export as, then click the "Go" button. You will be prompted to
choose a file to save to. If there are any problems during the export,
an error dialog will appear; otherwise the export was successful.
