# Example (JKQTPlotter): Plotting Arrows {#JKQTPlotterGeometricArrows}
This project shows the capabilities of JKQTPlotter to also draw arrows as geometric elements, using JKQTPGeoArrow. The arrow head/tail are defined by the enum values in JKQTPLineDecoratorStyle.
The source code of the main application can be found in [`geo_arrows.cpp`](https://github.com/jkriege2/JKQtPlotter/tree/master/examples/geo_arrows/geo_arrows.cpp). First a plot is generated. Then several types of arrows are plotted onto the JKQtPlotter.
## Different types of arrows
A first table shows all available arrow tips in different sizes.
```.cpp
for (size_t i=0; i<static_cast<size_t>(JKQTPLineDecoratorCount); i++) {
auto const decor=static_cast<JKQTPLineDecoratorStyle>(i);
plot.addGraph(a=new JKQTPGeoArrow(&plot, 0.1, arr_y, 0.3, arr_y+0.05, QColor("red"), decor, JKQTPNoDecorator, 0.2));
plot.addGraph(a=new JKQTPGeoArrow(&plot, 0.4, arr_y, 0.6, arr_y+0.05, QColor("red"), decor, JKQTPNoDecorator, 0.5));
plot.addGraph(a=new JKQTPGeoArrow(&plot, 0.7, arr_y, 0.9, arr_y+0.05, QColor("red"), decor, JKQTPNoDecorator, 1));
plot.addGraph(a=new JKQTPGeoArrow(&plot, 1.0, arr_y, 1.3, arr_y+0.05, QColor("red"), decor, JKQTPNoDecorator, 2));
plot.addGraph(a=new JKQTPGeoArrow(&plot, 1.4, arr_y, 1.7, arr_y+0.05, QColor("red"), decor, JKQTPNoDecorator, 3));
plot.addGraph(new JKQTPGeoText(&plot, a->getX2()+0.05, a->getY2(), "\\verb{"+JKQTPLineDecoratorStyle2String(decor)+"}", 12, a->getLineColor()));
arr_y+=arr_deltay;
}
```
Here is the resulting table:
![geo_arrow_tips](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/doc/images/geo_arrow_tips.png)
Note how the head-size scales with the line-width, but not linearly, but rather sub-linearly, so the tips do not grow too strongly.
Also note that all arrows end at the designated line-end (here indicated by dashed grey lines), even circles and rectangle:
![geo_arrow_tipsatlineend](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/doc/images/geo_arrow_tipsatlineend.png)
## Classes with support for arrows
You can use JKQTPGeoArrow and JKQTPGeoLine to draw arrows (JKQTPGeoArrow is just a convenience class that enables arrows by default, otherwise it is equal to JKQTPGeoLine).
In addition, also other classes can show line-decorators:
- JKQTPGeoLine
- JKQTPGeoPolyLines
- JKQTPGeoInfiniteLine
.
Here is an example of how to actiavate them for a JKQTPGeoPolyLines:
```.cpp
QVector<QPointF> points; points<<QPointF(3, 0.6)<<QPointF(4, 0.5)<<QPointF(3, 1.2)<<QPointF(4, 1.0);
JKQTPGeoPolyLines* polyLine=new JKQTPGeoPolyLines(&plot, points, QColor("blue"));
polyLine->setHeadDecoratorStyle(JKQTPFilledDoubleArrow);
polyLine->setTailDecoratorStyle(JKQTPCircleDecorator);
plot.addGraph(polyLine);
```
Here is the result:
![geo_arrow_polylines](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/doc/images/geo_arrow_polylines.png)
For the class JKQTPGeoInfiniteLine the start can be decorated with an arrow (only if two_sided==false!):
```.cpp
JKQTPGeoInfiniteLine* infLine=new JKQTPGeoInfiniteLine(&plot, 1.5, 0.2, 1, 0.25, QColor("blue"), 2);
infLine->setHeadDecoratorStyle(JKQTPFilledDoubleArrow);
plot.addGraph(infLine);
```
Here is the result:
![geo_arrow_polylines](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/doc/images/geo_arrow_inflines.png)
## Screenshot
The result of the complete example looks like this:
![geo_arrows](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/geo_arrows.png)
