Base class for plot items representing a series of samples.

xMap | Maps x-values into pixel coordinates. |
yMap | Maps y-values into pixel coordinates. |

pure virtual |
Draw a subset of the samples
painter | Painter |
xMap | Maps x-values into pixel coordinates. |
yMap | Maps y-values into pixel coordinates. |
canvasRect | Contents rect of the canvas |
from | Index of the first point to be painted |
to | Index of the last point to be painted. If to < 0 the curve will be painted to its last point. |
Implemented in QwtPlotCurve, QwtPlotIntervalCurve, QwtPlotHistogram, and QwtPlotSpectroCurve.
Qt::Orientation QwtPlotAbstractSeriesItem::orientation | ( | ) | const |
void QwtPlotAbstractSeriesItem::setOrientation | ( | Qt::Orientation | orientation | ) |
Set the orientation of the item.
The orientation() might be used in specific way by a plot item. F.e. a QwtPlotCurve uses it to identify how to display the curve int QwtPlotCurve::Steps or QwtPlotCurve::Sticks style.
