<hr><a name="_details"></a><h2>Detailed Description</h2>
A 2-D plotting widget.
<p>
<p>
QwtPlot is a widget for plotting two-dimensional graphs. An unlimited number of data pairs can be displayed as curves in different styles and colors. A plot can have up to four axes, with each curve attached to an x- and a y axis. The scales at the axes are dimensioned automatically using an algorithm which can be configured separately for each axis. Linear and logarithmic scaling is supported. Markers of different styles can be added to the plot.
<p>
Curves and markers are identified by unique keys which are generated automatically when a curve or a marker is created. These keys are used to access the properties of the corresponding curves and markers.
<p>
A QwtPlot widget can have up to four axes which are indexed by the constants QwtPlot::yLeft, QwtPlot::yRight, QwtPlot::xTop, and QwtPlot::xBottom. Curves, markers, and the grid must be attached to an x axis and a y axis (Default: yLeft and xBottom).<dl compact><dt>
<b>Example</b><dd>
The following example shows (schematically) the most simple way to use QwtPlot. By default, only the left and bottom axes are visible and their scales are computed automatically. <div class="fragment"><pre>
#include "../include/qwt_plot.h>
QwtPlot *myPlot;
long curve1, curve2; // keys
double x[100], y1[100], y2[100]; // x and y values
myPlot = new QwtPlot("Two Graphs", parent, name);
// add curves
curve1 = myPlot->insertCurve("Graph 1");
curve2 = myPlot->insertCurve("Graph 2");
getSomeValues(x, y1, y2);
// copy the data into the curves
myPlot->setCurveData(curve1, x, y1, 100);
myPlot->setCurveData(curve2, x, y2, 100);
// finally, refresh the plot
myPlot->replot();
</div></pre> </dl>
