到处搜索并阅读有关此的所有帖子，但找不到匹配项，所以这里是：
有一个使用 pchart 库编写的 Codeigniter/PHP 图形/图表应用程序。在 Windows 7 上本地运行良好，但是当我使用 OpenShift 时，标签和所有文本都丢失了。图像显示正确 - 图像中没有轴标签或自由文本。
在 OpenShift PHP 上启用了 GD 支持。
字体都在正确的地方。
文件路径变量（我使用的是“APPPATH”）经过测试并指向正确的位置。
应该在的所有字体。
帮助！
编辑：这里有一些代码： 当然可以。不知道你们是 php 还是 pchart 专家，但你去吧：

/* Draw the background */
$Settings = array("R"=>255, "G"=>255, "B"=>255, "Dash"=>0, "DashR"=>0, "DashG"=>0, "DashB"=>0);
$this->pImage->drawFilledRectangle(0,0,$chartWidth,$chartHeight,$Settings);
/* Add a border to the picture */
$this->pImage->drawRectangle(0,0,$chartWidth-1,$chartHeight-1,array("R"=>0,"G"=>0,"B"=>0));
