Question

我无法在3D饼图上更改主题或切片的颜色。我的代码是：

$graph = new PieGraph(350,250);
$graph->SetShadow();

$graph->title->SetFont(FF_VERDANA,FS_BOLD,18); 
$graph->title->SetColor("darkblue");
$graph->legend->Pos(0.1,0.9);

// Create 3D pie plot
$p1 = new PiePlot3d($data);
$p1->SetLegends($legends);
$p1->SetTheme("earth");
$p1->SetCenter(0.4);
$p1->SetSize(100);
$p1->SetSliceColors(array("red","blue","yellow","orange"));

$p1->SetAngle(45);

$p1->value->SetFont(FF_ARIAL,FS_BOLD,8);
$p1->value->SetColor("navy");

$graph->Add($p1);

无论我做什么，颜色都不会改变。我想念什么吗？

在更改主题和颜色之前，将图添加到图形中。如果您考虑一下，这是很有意义的。您必须先创建（定义/添加）某些内容，然后才能对其进行修改。

下面显示的更改应该起作用：

class SupressSettingWithCopyWarning:
    def __enter__(self):
        pd.options.mode.chained_assignment = None

    def __exit__(self, *args):
        pd.options.mode.chained_assignment = 'warn'

with SupressSettingWithCopyWarning():
    #code that produces warning
