我有一个图表,其中有沿y1轴的收入和沿y2轴的收入增长。我想使用后缀y1和%y2自定义工具提示。
我已尝试基于c3js文档实现以下代码。
tooltip: {
format: {
value: function(value) {
return d3.format(",") (value);
}
}
}
这将格式化两个轴的数千个值。我不确定如何在y1轴上执行此操作,除了为y2轴添加%之外。
对js还是陌生的,我不确定如何进行。
答案 0 :(得分:0)
您可以指定y和y2轴的值格式,如下所示:
tooltip: {
format: {
title: function (d) { return 'Data point ' + d; },
// this sets tooltip title
value: function (value, ratio, id) {
var format = id === 'data1' ? d3.format(',') : function (d) { return d + '%'; };
return format(value);
} // this formats y and y2 values
}
}
我为您创建了一个小提琴来测试此功能:http://jsfiddle.net/1kqcsywm/
这是相应的代码和可执行代码段:
var chart = c3.generate({
data: {
columns: [
['data1', 30000, 20000, 10000, 40000, 15000, 250000],
['data2', 100, 20, 10, 40, 15, 25]
],
axes: {
data2: 'y2'
}
},
axis : {
y : {
tick: {
format: d3.format("s")
},
label: {
text: 'Revenue',
position: 'outer-middle'
}
},
y2: {
show: true,
tick: {
format: function (d) { return d + '%'; }
},
label: {
text: 'Revenue growth',
position: 'outer-middle'
}
}
},
tooltip: {
format: {
title: function (d) { return 'Data point ' + d; },
// this formats tooltip title
value: function (value, ratio, id) {
var format = id === 'data1' ? d3.format(',') : function (d) { return d + '%'; };
return format(value);
}
// this formats y and y2 values
}
}
});

有关更多选项,您可以检查C3.js参考,它非常好:https://c3js.org/reference.html
编辑:您可以将逗号分隔符和前缀组合为工具提示值,例如:
tooltip: {
format: {
title: function (d) { return 'Data point ' + d; },
// this formats tooltip title
value: function (value, ratio, id) {
var format = id === 'data1' ? function(d) { return "Rs. " + d3.format(",")(d); } : function (d) { return d + '%'; };
return format(value);
}
// this formats y and y2 values
}
}
