У меня есть этот код, над которым я работаю, и мне нужна помощь. Линейный график не будет отображаться как есть. Время по оси X моего линейного графика не показывает интервал от 00:00:00 до 23:00:00. Он просто показывает 3:00, 9:00, 12:00, 15:00, 18:00 и 21:00, и данные также не будут отображаться по оси Y. Я ожидал, что он покажет 0,10,20 ... 100, как на картинке ниже:
Но ошибка, которую я получаю, это всякий раз, когда я смотрю на консоль: <path> attribute d: Expected number, "M0,NaNL38.695652173…"
Я думаю, что это делает его проблемой. Но пока это единственная ошибка, которую я получаю. Может кто-нибудь, пожалуйста, помогите мне ..
Это фрагмент моего кода:
$(document).ready(() => {
// set the dimensions and margins of the graph
var margin = { top: 20, right: 20, bottom: 30, left: 50 },
width = 1000 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
// parse the date / time
var parseTime = d3.timeParse("%H:%M:%S");
// 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) { return x(d.availability_time); })
.y(function (d) { return y(d.total_hour_percentage); });
// append the svg obgect to the body of the page
// appends a 'group' element to 'svg'
// moves the 'group' element to the top left margin
var svg = d3.select("#lineChart").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 + ")");
function draw(data) {
console.log(data[0].availability_time);
// format the data
data.forEach(function (d) {
d.availability_time = (parseTime(d.availability_time));
d.total_hour_percentage = d.total_hour_percentage;
});
// sort time ascending
data.sort(function (a, b) {
return a["availability_time"] - b["availability_time"];
})
// Scale the range of the data
x.domain(d3.extent(data, function (d) {
return d.availability_time;
}));
y.domain([0, d3.max(data, function (d) {
return Math.max(d.total_up_percentage);
})]);
// Add the valueline path.
svg.append("path")
.data([data])
.attr("class", "line")
.attr("d", valueline);
// Add the X Axis
svg.append("g")
.attr("transform", "translate(0," + height + ")")
.call(d3.axisBottom(x));
// Add the Y Axis
svg.append("g")
.call(d3.axisLeft(y));
}
// Get the data
// var perHourResult = "/perHourAvailabilities/" + defaultDate;
// console.log(perHourResult);
var perHourResult =
