## 5.14. Example - Stacked Bars, Shaded

This is a stacked bar chart, with the default 3-D shaded look. (Compare with Example 5.15, “Stacked Bars, Unshaded” which has no shading.) The only valid data types for stacked bars are 'text-data' (for vertical plots), and 'text-data-yx' (for horizontal plots).

    <?php
    # PHPlot Example: Stacked Bars, shaded
    require_once 'phplot.php';

    $data = array(
      array('Jan', 40, 5, 10, 3), array('Feb', 90, 8, 15, 4),
      array('Mar', 50, 6, 10, 4), array('Apr', 40, 3, 20, 4),
      array('May', 75, 2, 10, 5), array('Jun', 45, 6, 15, 5),

    $plot->SetImageBorderType('plain');

    $plot->SetPlotType('stackedbars');
    $plot->SetDataType('text-data');
    $plot->SetDataValues($data);

    $plot->SetTitle('Candy Sales by Month and Product');

    $plot->SetXTickLabelPos('none');
    $plot->SetXTickPos('none');

    $plot->DrawGraph();
