<div class="textblock"><p>A 2-D plotting widget. </p>
<p><a class="el" href="class_qwt_plot.html" title="A 2-D plotting widget.">QwtPlot</a> is a widget for plotting two-dimensional graphs. An unlimited number of plot items can be displayed on its canvas. Plot items might be curves (<a class="el" href="class_qwt_plot_curve.html" title="A plot item, that represents a series of points.">QwtPlotCurve</a>), markers (<a class="el" href="class_qwt_plot_marker.html" title="A class for drawing markers.">QwtPlotMarker</a>), the grid (<a class="el" href="class_qwt_plot_grid.html" title="A class which draws a coordinate grid.">QwtPlotGrid</a>), or anything else derived from <a class="el" href="class_qwt_plot_item.html" title="Base class for items on the plot canvas.">QwtPlotItem</a>. A plot can have up to four axes, with each plot item attached to an x- and a y axis. The scales at the axes can be explicitely set (<a class="el" href="class_qwt_scale_div.html" title="A class representing a scale division.">QwtScaleDiv</a>), or are calculated from the plot items, using algorithms (<a class="el" href="class_qwt_scale_engine.html" title="Base class for scale engines.">QwtScaleEngine</a>) which can be configured separately for each axis.</p>
