我使用d3.js v4在我早期的静态大小的情节中有完全足够的刻度;一旦我将其调整大小,滴答和值就会从y轴上消失。

提交者功能需要更多细节,但我没有...... 胡说 胡说 胡说 胡说 添加到填充非代码内容的字符。
蜱现在在y轴上消失了。我已将.tick属性添加到y轴,但没有欢乐。
如何让我的y轴回到图表的响应版本? TIA
稍后发布:有人吗?我的无响应版本的代码正在绘制; &#34; responsifying&#34;它使y轴刻度和单位消失。我几乎尝试了命令排序和放置的所有排列,但没有运气。

这里发生的是您的Y轴刻度被隐藏,因为它们不在视口中。您需要做的是将svg中的所有元素放在<g>
包装器中,并按左边距和上边距进行翻译。
这是一个小提琴
var chartDiv = document.getElementById("chart");
var svg = d3.select(chartDiv).append("svg");
var g = svg.append('g');
function render() {
$('svg').empty();
// Extract the width and height that was computed by CSS.
var width = $('#chart').width();
var height = $('#chart').height();
// Use the extracted size to set the size of an SVG element.
svg
.attr("width", width)
.attr("height", height);
// set the dimensions and margins of the graph
var margin = {
top: 20,
right: 20,
bottom: 50,
left: 40
};
width = width - margin.left - margin.right,
height = height - margin.top - margin.bottom;
// parse the date time
var parseTime = d3.timeParse("%m/%d %H:%M");
// set the ranges
var x = d3.scaleTime().range([0, width]);
var y = d3.scaleLinear().range([height, 0]);
// define the line
var valueline = d3.line()
.x(function(d) {

快乐编码:)
答案 1 :(得分:0)
知道了 - 轴刻度从窗口的左边缘消失 - 用转换/翻译修复:
// Add the Y Axis
svg.append("g")
.attr("transform", "translate(40 ,10)")
.call(d3.axisLeft(y));
...具有类似的x轴和匹配路径的平移。
此外,轴刻度现在出现的范围为0到1.0,因为它是一个异步操作,因为它没有被传递出文件读取循环。将svg.append引入数据读取循环使我的“正常”单位恢复到轴。
