Class ezcGraphAxisRotatedBoxedLabelRenderer

Can render axis labels rotated, so that more axis labels fit on one axis.

Produces best results if the axis space was increased, so that more spcae is available below the axis.

  1.    $chart->xAxis->axisLabelRenderer = new ezcGraphAxisRotatedLabelRenderer();
  3.    // Define angle manually in degree
  4.    $chart->xAxis->axisLabelRenderer->angle = 45;
  6.    // Increase axis space
  7.    $chart->xAxis->axisSpace = .2;
