<b>What you will learn in this chapter. </b>
|
|||
|
|
This chapter will illustrate how a basic line and bar graph can be created and it
|
|||
|
|
will also show how input data should be prepared so it can be read and used by the
|
|||
|
|
library.

<p>In order to quickly show a very first example we will create both a basic line
|
|||
|
|
graph and a basic bar graph that depicts the number of sun spots (a.k.a. solar
|
|||
|
|
flares) during the 19th century. The goal of this example is not to show every
|
|||
|
|
possible configuration and parameter supported by the library but rather show how
|
|||
|
|
simple it is to create a basic graph.</p>
|
|||
|
|
<p>In the sections following this one we will describe more in details the
|
|||
|
|
idiosyncrasies about dynamic graph generation and JpGraph so even if you don't fully
|
|||
|
|
understand all the detail it will give a flavor of what is to come. As with all
|
|||
|
|
complex libraries one has to start somewhere and sometimes accept some practices
|
|||
|
|
without yet fully understand them. However, the goal of this manual is that after
|
|||
|
|
reading it through you will fully understand every single detail shown in this
|
|||
|
|
script.</p>
|
|||
|
|
<p>So, without further due, let's start.</p>
