Hej伙计们,我尝试了2到3个不同的功能,但我无法让它们中的任何一个工作。我希望3种不同统计数据中的标签颜色为白色。下面是一张图片。
var options = {'title':'Lead statistik von<?php echo $_SESSION['user_name'];?>',
'width':400,
'height':300,
backgroundColor:'#0a0a0a',
fontSize:'14',
titleTextStyle: {color:'#FFFFFF'},
slices:
{
0: { color: 'red' },
1: { color: 'purple'},
2: { color: 'blue'}
},
pieSliceTextSlice:{color:'#FFFFFF'}
};
有人提示使用哪种功能?

要指定图例文字颜色,请使用legend.textStyle.color
属性,例如:
var options = {
legend: {
textStyle: { color: 'white' }
}
};
legend.textStyle
指定图例文本样式的对象。对象有这个 格式:
{ color: <string>, fontName: <string>, fontSize: <number>, bold: <boolean>, italic: <boolean> } The color can be any HTML color string, for example: 'red' or '#00cc00'. Also see fontName and fontSize. Type: object Default: {color: 'black', fontName: <global-font-name>, fontSize: <global-font-size>}
