-  \section jkqtplotter_graphsgroup_classstructure_basics Graph Class Structure
-
-  Each type of graph is represented by another class, which has to be derived from JKQTPPlotElement. This class provides a basic virtual interface
-  that allows JKQTPlotter to draw the graphs represented by them. This interface consists of these functions:
-    - JKQTPPlotElement::draw() draws the graph onto a given JKQTPEnhancedPainter (derived from <a href="http://doc.qt.io/qt-5/qpainter.html">QPainter</a>)
-    - JKQTPPlotElement::drawKeyMarker() draws the small marker image in the plot legend
-    - JKQTPPlotElement::getKeyLabelColor() returns a color for the legend entry for the graph
-    - JKQTPPlotElement::getXMinMax() returns the extent of the graph in x-direction (e.g. for auto-zooming)
-    - JKQTPPlotElement::getYMinMax() returns the extent of the graph in Y-direction (e.g. for auto-zooming)
-  .
-  In addition to these basic functions, there are additional functions that can be used to draw something outside the actual plot rectangle.
-  These are used to e.g. add color-scales to the side of the graph:
-    - JKQTPPlotElement::getOutsideSize() returns the amount of space required outside the plot rectangle
-    - JKQTPPlotElement::drawOutside() draws the elements outside the plot rectangle
-  .
-
-  Usually if writing a new graph, one would not directly
-  derive from JKQTPPlotElement, but from a cass in it's hirarchy of children. These children already provide certain facilities for certain types of graphs.

-  \section jkqtplotter_graphsgroup_classstructure_mixins Mix-In Classes for Graphs
-
-  \see \ref jkqtplotter_mixins
-
-  In addition there are mix-in classes that are used via multiple inheritance
-  that add additional features and properties to a graph. A prominent example are the classes for \ref jkqtplotter_basegraphserrors "error indicators".
-  With these there are usually two variants of one type of graph: One without error indicators and one with error indicators, e.g.:
-    - JKQTPXYLineGraph shows lines+symbols graphs made up from x/y-value pairs for each data point.
-    - JKQTPXYLineErrorGraph extends JKQTPXYLineGraph with error indicator drawing/properties provided by JKQTPXYGraphErrors
-  .
-  This approach allows to keep interfaces and appearance recognizeable over different graph classes and locates the source code
-  for a feature like error indicators in a single/in few class(es).
-
-  Another example of such a class is JKQTPColorPaletteStyleAndToolsMixin, which provides functions that allow to use color palettes. It is 
-  mainly used for the \ref jkqtplotter_imagelots "Image/Matrix graphs", but also by e.g. JKQTPXYParametrizedScatterGraph.

 Here is a short summary of the important parts of the code:

+
+First we need to set up the plotter and then generate some data for our plot. Here we use a simple random walk (with normally distributed steps) to simulate the price of some virtual stock. We simulate severals steps ofer <code>NDays</code> days and then calculate the necessary statistics over each day (i.e. the opening and closing price, as well as the daily maximum and minimum). Alternatively you could of course also load actual stock price data and read it in youself.
+
 ```.cpp
+    // 1. setup a plotter window and get a pointer to the internal datastore (for convenience)
+    JKQTPlotter plot;
+    JKQTPDatastore* ds=plot.getDatastore();
+
+    // 2. now we create 5 datacolumns with length Ndays entries in the datastore
+    //    these will later hold the time-step and simulated market data of two stocks
+    const size_t NDays=31;
+    const size_t columnT=ds->addColumn("time");
+    const size_t columnO1=ds->addColumn("open(stock 1)");
+    const size_t columnC1=ds->addColumn("close(stock 1)");
+    const size_t columnL1=ds->addColumn("low(stock 1)");
+    const size_t columnH1=ds->addColumn("high(stock 1)");
+    const size_t columnO2=ds->addColumn("open(stock 2)");
+    const size_t columnC2=ds->addColumn("close(stock 2)");
+    const size_t columnL2=ds->addColumn("low(stock 2)");
+    const size_t columnH2=ds->addColumn("high(stock 2)");
+    const QDate t0(2024,1,8); // start date
+
+    // 3. now we simulate stock market data with a simple random walk
+    //    with a few steps per day that are summmarized into the four
+    //    properties Open,Close,Low,High for each day
+    double price1=30; // start price of stock 1
+    double price2=25; // start price of stock 2
+    const size_t stepsPerDay=20;
+    std::random_device rd; // random number generators:
+    std::mt19937 gen{rd()};
+    gen.seed(12352);
+    std::normal_distribution<double> dist1(0.001, 0.6);
+    std::normal_distribution<double> dist2(-0.0001, 0.4);
+    for (size_t t=0; t<NDays; t+=1) {// iterate over all simulated days (we don't care for weekends)
+        // step time from noon to noon in steps of days
+        const QDate d=t0.addDays(t);
+        ds->appendToColumn(columnT, QDateTime(d,QTime(12,0,0)).toMSecsSinceEpoch());
+        // the open-Value is the start-price of each day:
+        ds->appendToColumn(columnO1, price1);
+        ds->appendToColumn(columnO2, price2);
+
+        // now we iterate the market over the day
+        double L1=price1, L2=price2, H1=price1, H2=price2;
+        for (size_t i=0; i<stepsPerDay; i++) { // iterate over week days (Mon-Fri)
+            // prices are calculated from a sinple random walk (the while-loops ensure that we have positive prices only
+            double np;
+            while ((np=price1+dist1(gen))<=0.0); price1=np;
+            while ((np=price2+dist2(gen))<=0.0); price2=np;
+            // now we track the highest/lowest prices
+            L1=qMin(L1, price1);
+            L2=qMin(L2, price2);
+            H1=qMax(H1, price1);
+            H2=qMax(H2, price2);
+        }
+        // the close-Value is the final price of each day:
+        ds->appendToColumn(columnC1, price1);
+        ds->appendToColumn(columnC2, price2);
+
+        // finally we just have to add the highest and lowest prices of each day:
+        ds->appendToColumn(columnL1, L1);
+        ds->appendToColumn(columnL2, L2);
+        ds->appendToColumn(columnH1, H1);
+        ds->appendToColumn(columnH2, H2);
+    }
 ```

+Now we have all columns necessary for two JKQTPFinancialGraph graphs.The first graph will be drawn in the CandleStick style and the second in the OHLC-sytle:
+
+```.cpp
+
+    // 3. create two JKQTPFinancialGraph to display the data:
+    JKQTPFinancialGraph* graphCandleStick=new JKQTPFinancialGraph(&plot);
+    graphCandleStick->setXColumn(columnT);
+    graphCandleStick->setOpenColumn(columnO1);
+    graphCandleStick->setHighColumn(columnH1);
+    graphCandleStick->setLowColumn(columnL1);
+    graphCandleStick->setCloseColumn(columnC1);
+    graphCandleStick->setGraphType(JKQTPFinancialGraph::CandleStick);
+    graphCandleStick->setTitle(QObject::tr("stock 1 (candlestick)"));
+    graphCandleStick->setCandlestickTwoColor(QColor("darkgreen"), QColor("maroon"));
+
+    JKQTPFinancialGraph* graphOHLC=new JKQTPFinancialGraph(&plot);
+    graphOHLC->setXColumn(columnT);
+    graphOHLC->setOpenColumn(columnO2);
+    graphOHLC->setHighColumn(columnH2);
+    graphOHLC->setLowColumn(columnL2);
+    graphOHLC->setCloseColumn(columnC2);
+    graphOHLC->setGraphType(JKQTPFinancialGraph::OHLC);
+    graphOHLC->setTitle(QObject::tr("stock 2 (OHLC)"));
+    graphOHLC->setOHLCTwoColor(QColor("darkgreen"), QColor("maroon"));
+
+    // 4. add the graphs to the plot, so it is actually displayed
+    plot.addGraph(graphCandleStick);
+    plot.addGraph(graphOHLC);
+
+```
+
+Finally we only have to format the plot and coordinate axes slightly to produce a nicer and better readable plot:
+
+```.cpp
+
+
+    // 5. scale the plot so the graph is contained and make x-axis a date-axis
+    plot.getXAxis()->setTickLabelType(JKQTPCALTdate);
+    plot.getXAxis()->setAxisLabel("time");
+    plot.getXAxis()->setTickLabelAngle(35); // rotate axis tick label by 35°, so they are readable
+    plot.getYAxis()->setAxisLabel("stock price [\\$]");
+    plot.getMainKey()->setPosition(JKQTPKeyInsideTopLeft);
+    plot.zoomToFit();```
+

 The result looks like this:

 ![financialgraphs](https://raw.githubusercontent.com/jkriege2/JKQtPlotter/master/screenshots/financialgraphs.png)


-By default, the length of the drawn vector is determined from the actual length in the data via an autoscaling algorithm that is supposed to prevent the vectors from overlapping.
-But you can modify this behaviour by adding a line 
-
-```.cpp
-        graph1->setVectorLengthMode(JKQTPVectorFieldGraph::LengthFromData);
-```
-
-which will use the given lengths directly (only scaled by an optional factor defined by JKQTPVectorFieldGraph::setLengthScaleFactor() ). The result then looks like this:

+ *  \section JKQTPFinancialGraphSideBySide Several Financial Graphs side-by-side
 *  In case you want to display several of these graphs in the same plot, you can make them appear side-by-side, even
 *  if they all cover the same x-values and would thus be draw atop each other. We apply the same principles that
 *  were used for barcharts in JKQTPBarGraphBase and add a shift-parameter (setShift() ) that shifts each element
 *  in the available space:
 *

+ *  \image html financialgraphs_shiftwidth.png
 *
 *  For example for two financial graph elements per x-value one would set:
 *  \verbatim
@ -80,8 +80,6 @@
 *        shift=-0.5 / +0.5
 *  \endverbatim
 *
- *  \image html financialgraphs_shiftwidth.png

 *  Two functions are provided (JKQTPFinancialGraph::autoscaleBoxWidthAndShift(), JKQTPFinancialGraph::autoscaleBoxWidthAndShiftSeparatedGroups() )
 *  that can be applied to any JKQTPFinancialGraph in the plot and will calculate all JKQTPFinancialGraphs' shift and width parameter
 *  in such a way that the graphs appear tidied up into groups by x-value. With these functions you don't have to calculate
