<h1>KPlotWidget Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: QFrame → QWidget → QObject<br />
<h2>Detailed Description</h2>
<p>KPlotWidget
</p>
<p>
Generic data plotting widget.
</p>
<p>
Widget for drawing plots. The basic idea behind KPlotWidget is that
you don't have to worry about any transformation from your data's
natural units to screen pixel coordinates; this is handled internally
by the widget.
</p>
<p>
Data to be plotted are represented by one or more instances of
KPlotObject. KPlotObject contains a list of QPointFs to be plotted
(again, in the data's natural units), as well as information about how
the data are to be rendered in the plot (i.e., as separate points or
connected by lines? With what color and point style? etc). See
KPlotObject for more information.
</p>
<p>
KPlotWidget automatically adds axis labels with tickmarks and tick
labels. These are encapsulated in the KPlotAxis class. All you have
to do is set the limits of the plotting area in data units, and
KPlotWidget wil figure out the optimal positions and labels for the
tickmarks on the axes.
</p>
<p>
Example of usage:
</p>
<p>
<pre class="fragment">
KPlotWidget *kpw = new KPlotWidget( parent );
// setting our limits for the plot
kpw->setLimits( 1.0, 5.0, 1.0, 25.0 );
// creating a plot object whose points are connected by red lines ...
KPlotObject *kpo = new KPlotObject( Qt.red, KPlotObject.Lines );
// ... adding some points to it ...
for ( float x = 1.0; x <= 5.0; x += 0.1 )
kpo->addPoint( x, x*x );
// ... and adding the object to the plot widget
kpw->addPlotObject( kpo );
</pre>
</p>
<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd> KPlotWidget will take care of the objects added to it, so when
clearing the objects list (eg with removeAllPlotObjects()) any previous
reference to a KPlotObject already added to a KPlotWidget will be invalid.
</dd></dl> </p>

All data points are *plotted* using the coordinates
defined by setLimits(), so this function is only useful for
showing alternate tickmark labels along the top and right
edges. For example, if you were plotting temperature on the
X-axis, you could use Centigrade units for the primary
(bottom) axis, using setLimits( 0.0, 100.0, 0.0, 1.0 ). If
you also wanted to show Farenheit units along the secondary
(top) axis, you would additionally use
setSecondaryLimits( 32.0, 212.0, 0.0, 1.0 ). The data
added to the plot would have x-coordinates in Centigrade degrees.
