Add strokeDashArray to setGrid method.

[hesami]

Update LarapexChart.php by adding the $strokeDashArray parameter to the setGrid method.

good idea, I added it (little bit more complex) in my fork in Version 1.4.1:

you can use it easily:

$chart = (new BarChart)
  ->setGridOptions(
      (new GridOption())->setStrokeDashArray(5)
);
