我在我的csv文件中有一些值,並且我在y軸和日期x軸上顯示了一個圖形。d3.js x軸日期範圍
對於第一圖表我具有以下值
date,close
13-Jul-16,0.8736701869033555

但在第二圖表的x軸不包含所有的日期。作爲一個例子,我放我的輸出圖表myoutput的打印屏幕在這裏。
這是我的代碼,它從csv文件中獲取數據並將其可視化。
var selectedMonth = document.getElementById('selectedMonth')。value; var selectedTopic = document.getElementById('selectedTopic').value;
var userFileDirectory="../documents/";
userFileDirectory=userFileDirectory+selectedMonth+"/"+selectedTopic+"/"+"dataCs.csv";
// Set the dimensions of the canvas/graph
var margin = {top: 30, right: 20, bottom: 30, left: 50},
width = 600 - margin.left - margin.right,
height = 270 - margin.top - margin.bottom;
// Parse the date/time
var parseDate = d3.time.format("%d-%b-%y").parse;
// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.scale.linear().range([height, 0]);
// Define the axes
var xAxis = d3.svg.axis().scale(x)
.orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
.orient("left").ticks(5);
// Define the line
var valueline = d3.svg.line()
.x(function(d) { return x(d.date); })
.y(function(d) { return y(d.close); });
// Adds the svg canvas
var svg = d3.select("body")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform",
"translate(" + margin.left + "," + margin.top + ")");
// Get the data
d3.csv(userFileDirectory, function(error, data) {
data.forEach(function(d) {
d.date = parseDate(d.date);
d.close = +d.close;
});
// Scale the range of the data
x.domain(d3.extent(data, function(d) { return d.date; }));
y.domain([0, d3.max(data, function(d) { return d.close; })]);
// Add the valueline path.
svg.append("path")
.attr("class", "line")
.attr("d", valueline(data));
// Add the X Axis
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
// Add the Y Axis
svg.append("g")
.attr("class", "y axis")
.call(yAxis);
svg.append("text")
.text("("+selectedMonth+" "+selectedTopic+")");
});
嗨 - 請分享代碼,特別是建立比例尺(域和範圍),軸和線功能的部分。另外,兩個圖表是否都使用相同的比例,座標軸和直線功能? –
