In this example we will access the data in the internal datastore directly. This access is possible through objects of type JKQTPcolumn, which is a proxy to the data in one of the columns in a `JKQTdatastore`:
```c++
JKQTPcolumn cG=ds->getColumn(columnG);
JKQTPcolumn cR=ds->getColumn(columnR);
JKQTPcolumn cB=ds->getColumn(columnB);
```c++
```
In order to calculate the histograms, first all enries in the columns are set to 0:
```c++
cR.setAll(0);
cG.setAll(0);
cB.setAll(0);
```
Finally the histogram is calculated:
```c++
QImage image(":/example.bmp");

Finally three `JKQTPfilledCurveXGraph` objects are generated and added to the plot (here we show the code for the R-channel only):
