Nice table values

What makes this view even more useful is that

the table keeps its ‘nice’ scale even while the

usual ‘FCN’ tools are being used. As you can

see in the screenshot left, the table is

automatically repositioned to show the closest

pixel value to that of the extremum found.

The Signed Area… tool is also available in this view and when the cursor is

moved the values in the table follow it. Unfortunately, the highlighted value in

the table doesn’t change as the cursor moves to create the shaded area. For

this reason the best strategy is to use the

key to jump to the end point.

This means that the area will not be shaded but this should not be a problem.

Overlay Plot

Another possibility from the VIEWS menu is Overlay Plot. This option can be

used to add another graph over the top of an existing one, without the screen

being blanked first as it usually is. As an example, if you have already

graphed functions F1(X) through to F6(X) and then add another one in the

SYMB view, then you don’t really want to have to wait while all the earlier

ones are redrawn. If you un-

the earlier graphs and then use Overlay

Plot for the new one then it will be drawn over the top of the existing ones.

Of course the results will not be good if the scales don’t match!.

You can even use this to combine different

styles of graphs. For example, the screen shot

right was produced by drawing a circle in the

Parametric aplet and then superimposing the

equations y = x and

y = -x in the Function aplet. This could be used

to show, for example, enclosing curves for conic sections.

You can also use this technique to overlay functions on top of statistical

graphs.
