 As shown in [Plotting Mathematical Functions as Line Graphs](https://github.com/jkriege2/JKQtPlotter/tree/master/test/simpletest_functionplot) you can also use externally set parameters in a plot function. These parameters can be double numbers and may be set with either as an internal parameter vector, or may be read from a parameter column (as shown in the [linked example](https://github.com/jkriege2/JKQtPlotter/tree/master/test/simpletest_functionplot)). These parameters are available as variables `p1`, `p2`, ... in the function string. Here is a small example:
 
 ```c++
-	JKQTPxParsedFunctionLineGraph* parsedFunc=new JKQTPxParsedFunctionLineGraph(plot);
+    JKQTPxParsedFunctionLineGraph* parsedFunc=new JKQTPxParsedFunctionLineGraph(plot);
     parsedFunc->set_function("sin(x*p1)*exp(-x/p2)");
-	parsedFunc->set_paramV(/*p1=*/8, /*p2=*/4);
+    parsedFunc->set_paramV(/*p1=*/8, /*p2=*/4);
     parsedFunc->set_title("user function");
 ```
