# Example (JKQTMathText): A test application {#JKQTMathTextTestApp}
JKQTMathText is a hand-written LaTeX-renderer for Qt (implemented in native C++, using Qt). It supports a large set of standard LaTeX markup and can render it to a QPainter.
This test program demonstrates its capabilites. There are several pre-formulated LaTeX expressions that can be drawn, or you can enter a user-defined expression.
You can also set several properties of the rendering (fonts, font sizes, anti-aliasing, ...). You can also draw boxes around each part of the expression (this is mostly meant for development/debugging). In the lower-right you will see the LaTeX expression as a tree after parsing and you will get timing-values for the parsing and rendering and error output.
The application looks like this:

# Example (JKQTPlotter): Boxplots {#JKQTPlotterBoxplotsGraphs}
This project (see [`simpletest_boxplot`](../simpletest_boxplot) demonstrates how to use JKQTPlotter to draw <a href="https://en.wikipedia.org/wiki/Box_plot">box plots</a> using the classes `JKQTPBoxplotVerticalGraph` and `JKQTPBoxplotHorizontalGraph`.
The source code of the main application is (see [`jkqtplotter_simpletest_boxplot.cpp`](jkqtplotter_simpletest_boxplot.cpp).
After adding all necessary data to the JKQTDatastore:
```.cpp
// 2. now we create data for the boxplots
QVector<double> POS, POSY, MEDIAN, MEAN, Q25, Q75, MIN, MAX;
POS << 1 << 4 << 7 << 10;
POSY << -1 << -2 << -3 << -4;
MIN << 2 << 3 << 2.5 << 6;
Q25 << 4 << 4.5 << 5 << 7;
MEDIAN << 5 << 6 << 7 << 9;
MEAN << 5.5 << 5.2 << 8 << 8;
Q75 << 6 << 7 << 9 << 11;
MAX << 8 << 7.5 << 11 << 12;
// 3. make data available to JKQTPlotter by adding it to the internal datastore.
size_t columnPOS=ds->addCopiedColumn(POS, "POS");
size_t columnPOSY=ds->addCopiedColumn(POSY, "POSY");
size_t columnMIN=ds->addCopiedColumn(MIN, "MIN");
size_t columnQ25=ds->addCopiedColumn(Q25, "Q25");
size_t columnMEDIAN=ds->addCopiedColumn(MEDIAN, "MEDIAN");
size_t columnMEAN=ds->addCopiedColumn(MEAN, "MEAN");
size_t columnQ75=ds->addCopiedColumn(Q75, "Q75");
size_t columnMAX=ds->addCopiedColumn(MAX, "MAX");
```
... you can generate the JKQTPBoxplotVerticalGraph:
```.cpp
// 4. create a graph of vertical boxplots:
JKQTPBoxplotVerticalGraph* graph=new JKQTPBoxplotVerticalGraph(&plot);
graph->set_posColumn(columnPOS);
graph->set_minColumn(columnMIN);
graph->set_percentile25Column(columnQ25);
graph->set_medianColumn(columnMEDIAN);
graph->set_meanColumn(columnMEAN);
graph->set_percentile75Column(columnQ75);
graph->set_maxColumn(columnMAX);
graph->set_title("vertical Boxplots");
```
You can further style the plot by e.g. setting:
```.cpp
// 4.1 make fill collor a lighter shade of the outline color
graph->set_fillColor(graphh->get_color().lighter());
// 4.2 make whiskers dashed
graph->set_whiskerStyle(Qt::DashLine);
// 4.3 change mean symbol
graph->set_meanSymbol(JKQTPstar);
```
The result looks like this:
![jkqtplotter_simpletest_boxplot](../../screenshots/jkqtplotter_simpletest_boxplot.png)
In addition to the simple box plots, the image above also shows outliers as small circles. these need to be drawn with a separate `JKQTPXYLineGraph`:
```.cpp
// add some outliers (as (x,y)-pairs)
QVector<double> OUTLIERSX, OUTLIERSY;
OUTLIERSX << 4 << 4 << 4 << 4 << 4 << 10 << 10 << 10 << 10 << 10 << 10 << 10;
OUTLIERSY << 1 << 0.5 << 1.3 << 8 << 8.1 << 5 << 4 << 12.2 << 13 << 12.5 << 13.5 << 13.1;
// 3. make data available to JKQTPlotter by adding it to the internal datastore.
...
size_t columnOUTLIERSX=ds->addCopiedColumn(OUTLIERSX, "OUTLIERSX");
size_t columnOUTLIERSY=ds->addCopiedColumn(OUTLIERSY, "OUTLIERSY");
// 4. create a graph of vertical boxplots:
...
// 5. outliers need to be drawn separately
JKQTPXYLineGraph* graphOutliers=new JKQTPXYLineGraph(&plot);
graphOutliers->set_xColumn(columnOUTLIERSX);
graphOutliers->set_yColumn(columnOUTLIERSY);
graphOutliers->set_title("outliers");
// make the color a darker shade of the color of graph
graphOutliers->set_color(graph->get_color().darker());
graphOutliers->set_fillColor(QColor("white"));
// draw outliers as small circles, without lines
graphOutliers->set_symbol(JKQTPCircle);
graphOutliers->set_drawLine(false);
graphOutliers->set_symbolSize(7);
```

Note that all the different variants to provide parameters can be used with all types of functions!
Also see the example [Plotting Parsed Mathematical Functions as Line Graphs](../simpletest_parsedfunctionplot) for details on how the actual plotting algorithm works.

That example also shows how to define a function as a string, which is then parsed and evaluated by an expression parser library embedded in JKQTPlotter.
All examples above use the graph class `JKQTPXFunctionLineGraph`, which plots a function `y=f(x)`. If you want to plot a function `x=f(y)`, you can use the class `JKQTPYFunctionLineGraph` instead. If in the examples above, we exchange all `JKQTPXFunctionLineGraph` for `JKQTPYFunctionLineGraph`, the graphs will be rotated by 90 degree, as all functions are interpreted as `x=f(y)`:

This project (see `./examples/simpletest_imageplot/`) simply creates a JKQTPLotter widget (as a new window) and adds a color-coded image plot of a mathematical function (here the Airy disk). The image is stored as a simple C-array in row-major ordering and then copied into a single column of the internal datasdtore (JKQTPMathImage could be directly used without the internal datastore). This very simple interface can also be used to interface with many common image processing libraries, like CImg or OpenCV.
# Example (JKQTPlotter): Simple math image plot {#JKQTPlotterImagePlot}
This project (see `./examples/simpletest_imageplot/`) simply creates a JKQTPlotter widget (as a new window) and adds a color-coded image plot of a mathematical function (here the Airy disk). The image is stored as a simple C-array in row-major ordering and then copied into a single column of the internal datasdtore (JKQTPMathImage could be directly used without the internal datastore). This very simple interface can also be used to interface with many common image processing libraries, like CImg or OpenCV.
