<h2>Graph2D | Performance</h2>

<div style="width:700px; font-size:14px; text-align: justify;">
|
|
This example shows the some of the graphs outlined on the right side using the <code>yAxisOrientation</code> option within the groups.
|
|
We also show a few more custom styles for the graphs. Finally, the legend is manually positioned. Both the left and right axis
|
|
have their own legend. If one of the axis is unused, the legend is not shown. The options for the legend have been split
|
|
in a <code>left</code> and a <code>right</code> segment. The default position of the left axis has been changed.
