<para>
&kchart; is an application for visualizing numerical data. It has many
different chart types available like bar graphs, line plots, pie charts,
ring charts and more.
</para>
<para>
&kchart; is a &koffice; component and is very well integrated with &kspread;
to allow visualization of spreadsheet data. But it is also possible to use
&kchart; as a standalone application or integrate it in other &koffice;
components.

<title>Introduction</title>

<para>
&kchart; is a tool for visualizing numerical data. It can be used
as a standalone application with a simple &dataeditor;. But as a
&koffice; component it offers very flexible integration. &kspread;
uses the &kchart; component for charts and diagrams. &kspread;
can be seen as a very powerful data provider for &kchart; input.
</para>
<para>
But embedding is not limited to &kspread;. A &kchart; chart can
be embedded in many of the &koffice; components like &kword;,
&kpresenter; or &kivio;.
</para>
<para>
To start with we will look at the user interface of &kchart;
and how it can be used as a standalone application. When we
are familiar with &kchart; we will investigate the charting
capabilities it offers together with &kspread;.
</para>
</chapter>

<chapter id="userinterface">
<title>The User Interface</title>
<sect1 id="mainuserinterface">
<title>Main Application Interface</title>
<para>
We will take a look at a simple example to get to know &kchart;.
Along the way we will also discuss the user interface at length
so you will learn about many details of the component.
</para>
<para>
When you start &kchart; as a standalone application you get
the usual startup dialog where you can choose between different
templates or load existing chart documents.
</para>
<screenshot>
<screeninfo>&kchart; Startup Dialog</screeninfo>
  <mediaobject>
    <imageobject>
      <imagedata fileref="kchart-startupdialog.png" format="PNG"/>
    </imageobject>
  </mediaobject>
</screenshot>
<para>
You can choose between various ways to startup &kchart;. On the left, you can
see three options: <guilabel>Recent Documents</guilabel>, 
<guilabel>Charts</guilabel> templates and <guilabel>Open Existing
Document...</guilabel>. The first option lets you choose between
recently opened charts, the second is for creating a
new chart from various templates and the third is for opening an existing
chart with a file dialog.
</para>
<para>
For now we will start with the default template. Select
<guilabel>Charts</guilabel> in the left area and then select
<guilabel>Bar Chart</guilabel> in the main template area. Normally
this template should already be selected after choosing
<guilabel>Charts</guilabel>. 
</para>
<para>
If you decide to always start &kchart; with a selected template as default
you can also check <guilabel>Always use this template</guilabel>.
</para>
<para>
Click  the <guibutton>Use This Template</guibutton>
button on the right, under the template preview.
</para>

  </mediaobject>
</screenshot>
<para>
As you can see, there is already some example data present. &kchart;
offers the default toolbar for creating a new chart, saving, loading
and printing the chart. The second toolbar offers icons for editing
the data, configuring the chart or using a configuration wizard.
You can also switch between different chart types with the rest
of the icons. Note that some of these chart types also have subtypes.
</para>
<para>
The menu offers all standard entries, including shortcut and
toolbar configuration and page layout for printing.
</para>
<para>
Note that data editing is not available if you use &kchart; from
within &kspread; because all data is provided by the spreadsheet.
As a standalone application the &dataeditor; is an important part
of the application.
</para>
</sect1>
<sect1 id="wizard">
<title>Chart Wizard</title>
<para>
The wizard is actually a very useful part of &kchart; for quickly
setting up some basic options like chart type and chart labelling
in a few easy steps.
</para>
<para>
You can run the wizard at any time, it will always preserve your data
and other configuration. Also, you can change every single configuration
you do with the wizard later as well, without losing anything. In fact
the wizard is just a way to set some basic and important options
in one go.
</para>
<para>
To start the wizard simply click on the
<inlinemediaobject><imageobject>
<imagedata fileref="cr22-action-wizard.png" format="PNG"/>
</imageobject></inlinemediaobject> icon in the toolbar.

The first step in the wizard is to actually choose the data source.
If the selected data area does not match the data you want,
select the data now.</para>
<para>
Include cells that you want to use as row and column labels,
if you want them in the chart.</para>
<para>
Then go to the next step with the <guibutton>Next &gt;</guibutton> 
button. You can also choose <guibutton>Finish</guibutton> at any step
if you are already comfortable with the setup done so far.

<para>
The next step in the wizard is to actually choose the primary
type of the chart. This selection has the most important
impact on how your data will be presented. Thus it should
be chosen well. You can change the type of the chart with the
icons in the toolbar without losing any data or configuration
later on. In fact it is even considered normal to test all the
various chart types to find the best fitting.
</para>
<para>
In this example we choose the <guilabel>Lines</guilabel> type. Depending on the
chosen chart type different options are available in the
following steps.
</para>
<para>
After chosing the type you can get to the next step with
the <guibutton>Next &gt;</guibutton> button.

choose it in the second step. If the chart type has no sub types,
this step will be skipped automatically.

If you decide to change the sub type later, you can do this
in the appropriate configuration dialog which will be shown
later.

You can simply leave the default selection and go to the next
step. Of course you can chose any desired sub type if you want.

The &dataeditor; can be used to set all values. You can also define
the number of rows and columns.
</para>
<para> Depending on the chart type rows and columns have different
representations. Each row can generally be considered to be one data
series or data set while each column represents the values of all
data sets at a certain location.
</para>
<para>
The name of a data set can be changed by clicking on the row header
(left of the first column with values). The name of a column can
be changed by clicking on the column header (above the first
row).

<para>
The number of rows and columns can be adjusted to fit the needs.
Since version 1.4 the restriction to 16 rows and 16 columns has been
eliminated.

clicking on the <inlinemediaobject><imageobject>
<imagedata fileref="cr22-action-data.png" format="PNG"/>
</imageobject></inlinemediaobject> icon in the toolbar.

You will notice that no data is present. Also note that
the number of data rows and columns is set to a minimum,
which is 1.

That's all what we need for a reasonable looking chart. Note
that much of this configuration could also have been achieved
with the wizard. It's basically a matter of taste what you
use. Experienced users will likely use the full option dialog

You might want to enlarge the application window to see the chart
in full size. Note how the fonts get larger in relation to the
chart size.

There are certainly aspects to improve further for your personal
taste. For example try to make the title font even bigger.
Just experiment further, this way you will get to know a lot
of the &kchart; application.

<para>
Finally you can save the chart from the <guimenu>File</guimenu>

<para>
For further processing, the chart can also be exported as a graphics file.
Many formats are available. Using either PNG, SVG, JPG or &chalk; will likely
produce the best result.
</para>
<para>

<chapter id="kchartinkspread">

<title>Using &kchart; in &kspread;</title>

<para>
In addition to standalone operation, &kchart; is designed to be used with
&kspread;. This chapter describes how to create and manipulate charts
from within &kspread;.
</para>
<para>
Remember that &kchart; embedding into &kspread; is a very commonly
used and well implemented feature, the examples in this chapter should
just get you started.
</para>
<para>
As soon as you have created a chart in &kspread; you can take full
advantage of all the &kchart; features by double clicking on the
chart area. This is necessary to get to all advanced configuration
options. Keep in mind that the data editor is not available when
&kchart; is embedded into &kspread;. This is obvious since &kspread;
serves, from &kchart;'s point of view, as a powerful data
provider.
</para>
<para>
Swapping x and y is of particular interest when working with &kspread;.
You can swap interpretation of x and y axis in &kchart; in the
Data Format settings which can be accessed through the Edit menu
or the context menu when right clicking on the chart itself. As noted
above you need to be inside the &kchart; component in order to access
these settings, which can be done by double clicking the embedded
chart in your spreadsheet.
</para>

<sect1 id="main_window">
<title>Plotting with &kchart;</title>
<para>To plot with &kchart;, when it is embedded in &kspread;, do the following:</para>

<para>
The whole data could also be created using two columns instead of
two rows. If using columns you might want to switch x and y axis
in the &kchart; configuration as described above.
</para>

<para>To make a bar chart for individual items, put the numbers in a
column, as shown below.</para>
