我正在尝试在 d3.js 中构建一个矩形网格。
网格为 7 行(一周中的天数)和 24 列(一天中的小时数)。
以下代码仅绘制(行:列):day0:hour0,day1:hour1,day2:hour2,day3:hour3,day4:hour4,day5:hour5,day6:hour6,day7:hour7
问题:任何想法为什么以下代码不起作用?
/**
* calendarWeekHour Setup a week-hour grid:
* 7 Rows (days), 24 Columns (hours)
* @param id div id tag starting with #
* @param width width of the grid in pixels
* @param height height of the grid in pixels
* @param square true/false if you want the height to
* match the (calculated first) width
*/
function calendarWeekHour(id, width, height, square)
{
var calData = randomData(width, height, square);
var grid = d3.select(id).append("svg")
.attr("width", width)
.attr("height", height)
.attr("class", "chart");
grid.selectAll("rect")
.data(calData)
.enter().append("svg:rect")
.attr("x", function(d, i) { return d[i].x; })
.attr("y", function(d, i) { return d[i].y; })
.attr("width", function(d, i) { return d[i].width; })
.attr("height", function(d, i) { return d[i].height; })
.on('mouseover', function() {
d3.select(this)
.style('fill', '#0F0');
})
.on('mouseout', function() {
d3.select(this)
.style('fill', '#FFF');
})
.on('click', function() {
console.log(d3.select(this));
})
.style("fill", '#FFF')
.style("stroke", '#555');
}
