Plotting Options

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.

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.


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!)


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 in the 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(x)-2cos(x) function from the previous section.
