The Graph01Demo program

The data displayed in Figure 1 was produced by a program named Graph01Demo. A listing of that program is shown in Listing 37 near the end of the module. I will explain that program in detail shortly.

In addition, I will provide and discuss another sample program, which produces and plots data having considerably more engineering and scientificsignificance than the data shown in Figure 1 . (This will be a digital signal processing (DSP) example). Even in that case, however, you will see that the program that produces the data is much less complex than the program used toplot the data.

Using the plotting program with your data

I will explain everything that you will need to know to cause the output from your own engineering and scientific programs to be displayed by the plottingprogram.

The Graph01 program

The graphical display of the data shown in Figure 1 was produced by my generalized plotting program named Graph01 . As you will see later, this is a long and fairly complex program.

You will find two more variations on this program in the programs named Graph03 and Graph06 in the module titled Java1482-Spectrum Analysis using Java, Sampling Frequency, Folding Frequency, and the FFT Algorithm .

A listing of the plotting program named Graph01 is shown in Listing 39 near the end of the module.

User need not understand the plotting program

Fortunately, the user of the plotting program doesn't need to understand anything about the code that makes up the plotting program. All the user needsto understand is the interface to the program, which I will explain later.

However, for those of you who may be interested, I will also discuss and explain the plotting program later in this module.

Plotting format

As you can see in Figure 1 , the plotting program allows for plotting up to five independent functions stacked vertically, each with the same vertical andhorizontal axes. This vertical stacking format makes it easy to compare up to five plots at the same points on the horizontal axes.

If you need more than five functions, the number of functions can easily be increased with a few minor changes to the program.

(I will also provide, but will not discuss, another version of the program, named Graph02 , which superimposes up to five plots on the same coordinate system. In somecases, that is a more useful form of display. You will find a complete listing of this program in Listing 40 near the end of the module.)

Plotting parameters

As you can also see in Figure 1 , a set of text fields and a button on the bottom of the frame make it possible for the user to modify the plottingparameters and to re-plot the same data with an entirely new set of plotting parameters.

(It is often true that important but subtle pieces of information can only be exposed by viewing the same data with different sets of plottingparameters.)

Same data, different parameters

Figure 2 shows the same data as in Figure 1 , but plotted with a different set of plotting parameters.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
