Next to your graph (assuming you have plotted something to your
liking using the Inputting Functions
section of this tutorial, or just winging it by yourself), there
is an button. By clicking on this,
you will bring up a window, usually with the
button highlighted. Notice that there are other options available to
you, namely Attributes , Labels, Colors, Plot
Bands, Help, and Close. In any window that appears,
there is always a Help button available to explain the function
of that window and the options within. We are going to look at four of the
options named above.
The Axes window has a number of options
available. The first of these are basically light switches that you
turn on and off by clicking on them. Watch your graph change as
you change the switches from to
There is also the option to change the range and the domain graphed
of the function. To do this, place the mouse in the desired window,
and change the number to your satisfaction. Once you have changed
all the values you didn't like, click on the
button. If the values you chose
are valid (in that the function exists within those parameters), the
graph will automatically change to reflex the new ranges. If not,
however, you will receive an error message telling you that the
function does not exist at a certain point. Be familiar with the
limitations of your chosen function.
- Grid: Will make a background grid for the graph
- Box: Will create a box around the graph
- Plot Legend: Allows you to see the plot with or without the legend
- Auto Scale: Redraws the plot with scale automatically calculated from the plot data
- Axes: Allows you to turn axes on and off
- Numerical Labels: Turns the numbers on the axes on and off
- Axes/Title Labels: Turns axes and title labels on and off
You may also change the tick marks on the axes. Enter in the
desired interval for the major tick marks, and choose between
0 and 10 for the minor tick marks (you may use the slide on the
side of these with the middle mouse button
if you find that easier). Again, once you have
changed the numbers, click on the
button. The graph should instantly reflect your wishes. It is
not often you run across instant gratification. Savor this experience.
Attributes has four
sections (Plot Type, Line Type, Marker Type, and
Data Sampling for Points to Be Displayed) all dealing with
the type of graph you are going to be viewing.
- 2D You may change the Line Type, but not the Marker
Type since there are no point markers in the normal 2D graph.
- Polymarker This will mark all points that fit the
function, but there is no connecting line. Choose a Marker
Type, but the Line Type does not apply.
- Discrete This is a standard discrete plot, so you may change the
Line Type, but again there is no marker so the Marker
Type is not applicable.
- Linemarker For this, you may change the Marker
Type, but not the line, since there will always be a solid line
between the markers.
- Bar Graph This is a standard bar graph, but you may
change the Line Type.
Of all of the windows you will open in your lifetime,
this one has
to be the most self-explanatory. In this window,
you may change the:
or you may CHANGE ALL FONTS in one swooping gesture.
Your font options are in Figure 10.

Make sure that when you are changing the titles, you have the mouse
in the box you wish to write in. Those arrows at the ends of the boxes
tell you that you must hit enter/return once you have finished
editing the particular title. (Remember to hit enter/return
for each edited title!)
Figure 10 -- Font Options
I find this one (Figure 11)
of the most satisfying tools there is.
You may very easily change the color of
anything within the graph.
What you may change:
This is, of course, assuming that you have clicked these options
Axes section. If they are , then
you will not receive an error message, but then again, nor will you
see any result. This lovely package gives you a huge
selection (Figure 12) to choose from.
Below is an example of what you can do with color power, using
the f(x) = sin(x²)-2cos(x) function from the previous section.
