Question

我正在使用chart，一个使用google chart tools的drupal模块。

我已经成功创建了图形，但我的问题是我想在Y轴上放置整数值。我正在制作总票数图表。因此，假设我有55票（总数）的民意调查。 Y轴范围应该是最大值属性。就像我们有A，B和C一样，A有25票，B有10票，C有20票。所以Y轴范围应该等于25，它们之间没有浮点值，如1.5或2.5。这是我的功能代码：

//theme the poll results block

  $html = $variables['results'];
  $pattern = "@class=\"text\"\>(.*)\</div\>@";
  preg_match_all($pattern, $html, $choices); //extract choices
  $pattern = "@style=\"width: (.*)%;\"@";
  preg_match_all($pattern, $html, $votes); //extract percentages
  $chart = array(
      '#chart_id' => 'poll_chart' . $variables[nid],
      '#type' => CHART_TYPE_BAR_V,
      '#size' => chart_size(600, 350),
      '#grid_lines' => chart_grid_lines(100,10 ),
      '#bar_size' => chart_bar_size(30, 50),
  );

// NEED TO FILL IN DATA TO MAKE CHART
  for ($c=0; $c < count($choices[1]); $c++) { //make labels and values
     $chart['#data_colors'][] = 'ff8e07';
     $chart['#data'][$choices[1][$c]] = $votes[1][$c]; //number of votes
     $chart['#legends'][] = $choices[1][$c] . " (" . $votes[1][$c] . "%)"; // labels
     $chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][0][] = chart_mixed_axis_label(t($choices[1][$c]))
     ;
     print $choice['chvotes'];
  }

  $chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][2][] = chart_mixed_axis_label(t('Choices'), 50);
  $chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][3][] = chart_mixed_axis_label(t('Votes'), 95);
  $chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][4][] = chart_mixed_axis_range_label(0, $variables['votes']);

  $variables['results'] = chart_render($chart); //render graph
