本文介绍了将y轴上的数字转换为字符串,K为千d3.js的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我使用d3.js图表​​绘制y轴和x轴..它的工作精细...但在y轴的值,你可以说范围是说0到10000,我想如果数字大于千它会带来K说如果数字是1000它将显示1K,对于15000它将显示在y轴上的滴答15K i am using d3.js charts to plot y axis and x axis .. its working fine ... but the values in y axis you can say range is say 0 to 10000 and i want if the number is greater than thousand it will come with K say if the number is 1000 it will show 1K, for 15000 it will show on y axis ticks 15K 如何做到。 。我不能为字符串值管理y.domain和range函数... how to do that .. i am not able to manupulate y.domain and range functions for the string values ... var y = d3.scale.linear().range([ height, 0 ]);y.domain([0, //d3.min(cities, function(c) { return d3.min(c.values, function(v) { return v.count; }); }), d3.max(cities, function(c) { return d3.max(c.values, function(v) { return v.count; }); }) ]);如何做到这一点有什么办法...请帮助how to do that is there any way to do ... please help 推荐答案从 API参考,我们看到 d3.formatPrefix var prefix = d3.formatPrefix(1.21e9);console.log(prefix.symbol); // "G"console.log(prefix.scale(1.21e9)); // 1.21我们可以这样使用var yAxis = d3.svg.axis() .scale(y) .ticks(5) .tickFormat(function (d) { var prefix = d3.formatPrefix(d); return prefix.scale(d) + prefix.symbol; }) .orient("left");但是,如果这正是你的意思,我们可以简化 d3.format(s) However, in case this is exactly what you mean, we can simplify using d3.format("s")var yAxis = d3.svg.axis() .scale(y) .ticks(5) .tickFormat(d3.format("s")) .orient("left"); 这篇关于将y轴上的数字转换为字符串,K为千d3.js的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
