PHP：gChartPHP - 向饼图添加可见值

发布于 2024-09-17 22:00:50 字数 615 浏览 2 评论 0原文

我正在使用 http://code.google.com/p/gchartphp/ 中的 gchart php 包装器。这是任何使用它的人都会遇到的问题。

您能否清晰地显示构成饼图切片的值？

<?php
$piChart = new gPieChart();
$piChart->setDimensions(650,300);
$piChart->addDataSet(array_values($type));
$piChart->setLabels(array_keys($type));
$piChart->setColors(array("F26134", "F1F1F1","FFC7A8","E6E6E6","171717"));
$piChart->setTitle("All Tickets by Issue Type");
?>

<img src="<?php print $piChart->getUrl();  ?>" />

是否有可能每个切片都显示这种格式 - “标签 (15)”

I'm using the gchart php wrapper from http://code.google.com/p/gchartphp/. This is a question for anyone out there using it.

Can you visibly display the values that make up slices of a pie chart?

<?php
$piChart = new gPieChart();
$piChart->setDimensions(650,300);
$piChart->addDataSet(array_values($type));
$piChart->setLabels(array_keys($type));
$piChart->setColors(array("F26134", "F1F1F1","FFC7A8","E6E6E6","171717"));
$piChart->setTitle("All Tickets by Issue Type");
?>

<img src="<?php print $piChart->getUrl();  ?>" />

Is it possible that for each slice it shows this sort of format - "label (15)"

您可以随时修改标签，使其符合您想要的格式。例如，这会将您的标签格式化为“名称（值）”格式：

<?php
function formatLabel(&$item, $key, $arr) {
    $item = $item . ' (' . $arr[$item] . ')';
}

$keys = array_keys($type);
array_walk($keys, 'formatLabel', $type);

$piChart = new gPieChart();
$piChart->setDimensions(650,300);
$piChart->addDataSet(array_values($type));
$piChart->setLabels($keys);
$piChart->setColors(array("F26134", "F1F1F1","FFC7A8","E6E6E6","171717"));
$piChart->setTitle("All Tickets by Issue Type");
?>

You can always modify your labels so that they fit in the format you want. For example, this will format your label into the format "Name (Value)" :

<?php
function formatLabel(&$item, $key, $arr) {
    $item = $item . ' (' . $arr[$item] . ')';
}

$keys = array_keys($type);
array_walk($keys, 'formatLabel', $type);

$piChart = new gPieChart();
$piChart->setDimensions(650,300);
$piChart->addDataSet(array_values($type));
$piChart->setLabels($keys);
$piChart->setColors(array("F26134", "F1F1F1","FFC7A8","E6E6E6","171717"));
$piChart->setTitle("All Tickets by Issue Type");
?>
