问题描述
是否可以在Google饼图中以不同颜色显示每个图例?我在饼图中有3个传说,我想用不同的颜色显示每个人。
a href =https://developers.google.com/chart/interactive/docs/gallery/piechart =nofollow> google说明:使用 legend.textStyle
选项并像这样分配它
对象{color:'black',fontName:< global-font-name> ;, fontSize:< global-font-size>}
pre>
一个指定图例文本样式的对象。该对象的格式如下:
$ b{color:< string> ;,
fontName :< string> ;,
fontSize:< number> ;,
bold:< boolean> ;,
italic:< boolean> }
颜色可以是任何HTML颜色字符串,例如:'red'或'#00cc00' 。另请参阅fontName和fontSize。
用于绘制图表中的每个pi图表
function drawChart(){// chart 1
var data = google.visualization.arrayToDataTable ,
['dataname1',13],['dataname2',83],
]);
var options = {
title:'chart 1',
pieSliceText:'label',
legend.textStyle:{color:'blue',fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart1'));
chart.draw(data,options);
函数drawChart(){//图表2
var data = google.visualization.arrayToDataTable([
['Language','Speakers(in millions)'],
['dataname1',13],['dataname2',83],
]);
var options = {
title:'chart 2',
pieSliceText:'label',
legend.textStyle:{color:'red',fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart2'));
chart.draw(data,options);
} function drawChart(){// chart 3
var data = google.visualization.arrayToDataTable([
['Language','Speakers(in millions)'],
['dataname1',13],['dataname2',83],
]);
var options = {
title:'chart 3',
pieSliceText:'label',
legend.textStyle:{color:'green',fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart3'));
chart.draw(data,options);
}
Is it possible to show each legend in different color in google pie chart? I have 3 legends in my pie chart and i want to show each one of them in different color.
解决方案
Yes, from google instructions:
use the legend.textStyle
option and assign it like so
Object {color: 'black', fontName: <global-font-name>, fontSize: <global-font-size>}
An object that specifies the legend text style. The object has this format:
{ 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.
so for each pi chart in the drawchart
function drawChart() {//chart 1
var data = google.visualization.arrayToDataTable([
['Language', 'Speakers (in millions)'],
['dataname1', 13], ['dataname2', 83],
]);
var options = {
title: 'chart 1',
pieSliceText: 'label',
legend.textStyle: { color: 'blue', fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart1'));
chart.draw(data, options);
}
function drawChart() {//chart 2
var data = google.visualization.arrayToDataTable([
['Language', 'Speakers (in millions)'],
['dataname1', 13], ['dataname2', 83],
]);
var options = {
title: 'chart 2',
pieSliceText: 'label',
legend.textStyle: { color: 'red', fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart2'));
chart.draw(data, options);
} function drawChart() {//chart 3
var data = google.visualization.arrayToDataTable([
['Language', 'Speakers (in millions)'],
['dataname1', 13], ['dataname2', 83],
]);
var options = {
title: 'chart 3',
pieSliceText: 'label',
legend.textStyle: { color: 'green', fontName: 'arial'}
},
};
var chart = new google.visualization.PieChart(document.getElementById('piechart3'));
chart.draw(data, options);
}
