@@ -57,9 +57,9 @@ There are different facor affecting the replot speed:
 1. *Anti-Aliasing:* If `JKQTPlotter` uses Anti-Aliasing for plotting, the plots are much nicer, but also about a factor of 3-4 slower. This is due to the increased amount of calculations, necessary in the drawing sub-system of Qt.
    You can configrue anti-aliasing with these calls:
    ```.cpp
-      plot.get_plotter()->set_useAntiAliasingForGraphs(false);
-      plot.get_plotter()->set_useAntiAliasingForSystem(false);
-      plot.get_plotter()->set_useAntiAliasingForText(false);
+      plot.getPlotter()->setUseAntiAliasingForGraphs(false);
+      plot.getPlotter()->setUseAntiAliasingForSystem(false);
+      plot.getPlotter()->setUseAntiAliasingForText(false);
 	```
 2. *Number of Graphs:* The number of plots (and also ther type and complexity) is a major imapct factor in the plotting speed. You can switch off a plot with the context menu:<br>![contextmenu_graph_visibility](../../screenshots/contextmenu_graph_visibility.png)
 3. *Axis Scales and Plot Appearance:* Replotting is done in two steps: First the plot with the axes, labels etc. is drawn. Then the graphs are draw on top. Therefore a replot is faster, if only the graphs change, because the background (plot) does not have to be replotted.

 ```
 
 Finally: When printing or saving an image of the plots, the plotter will no know anything about the arrangement of the plots and the plots cannot be printed/drawn in the same arrangement as in the window. If you want to arrange the plots in the same layout in a printout, as in the window, you will have to tell the main plot, in which arrangement to print the plots:
 
 ```.cpp
     // 3.6 ensure that the plot are printed/exported in whole, when printing in plotMain
-    plotMain->get_plotter()->set_gridPrinting(true);
-    plotMain->get_plotter()->addGridPrintingPlotter(0,1,plotResid->get_plotter());

+    plotMain->getPlotter()->addGridPrintingPlotter(1,1,plotResidHist->getPlotter());
 ```
 
 In the first line, grid-printing (i.e. the layouted printing of several graphs) is activated. Then the arrangement of the two slave plots `plotResid` and `plotResidHist` is defined as (`x,y`)-shifts with respect to the master plot `plotMain`.

  *
  * As JKQTPlotter is a standard Qt widget, you can also use it in Qt UI-files designed with the Qt From Designer (e.g. from within QTCreator).
- * For this to work you have to use the "Promote QWidget"-feature of the form designer. The steps you need to take are detailed below:
- *   # add a new UI-file to your project and open it in the Form Editor. Then right-click the form and select `Promote Widgets ...`:<br>

+ *   <li> add a new UI-file to your project and open it in the Form Editor. Then right-click the form and select `Promote Widgets ...`:
  *
- *   # In the dialog that opens, you have to define `JKQTPlotter` as a promotion to `QWidget` as shown below. Finally store the settings by clicking `Add` and closing the dialog with `Close`.<br>
