Angular2和D3.js甘特图 [英] Angular2 and D3.js Gantt chart

问题描述

我有一个angular2应用，我正在尝试从d3.js实施甘特图.我正在尝试使用以下示例 http://bl.ocks.org/dk8996/5538271 .显然，这是使用javascript而不是打字稿.但是，我似乎大部分都还可以，但是我遇到了一个问题.

I have an angular2 app which i am attempting to implement a Gantt chart from d3.js into. I am trying to use the following example http://bl.ocks.org/dk8996/5538271. obviously this uses javascript rather than typescript. However i have got most of it seeming ok, but i get one issue.

这是我的全部方法:

createSchedule() {
    var tasks = [{"startDate":new Date("Sun Dec 09 01:36:45 EST 2012"),"endDate":new Date("Sun Dec 09 02:36:45 EST 2012"),"taskName":"E Job","status":"RUNNING"}];
    var taskStatus = {
        "SUCCEEDED" : "bar",
        "FAILED" : "bar-failed",
        "RUNNING" : "bar-running",
        "KILLED" : "bar-killed"
    };

    var taskNames = [ "D Job", "P Job", "E Job", "A Job", "N Job" ];

    tasks.sort(function(a,b) {
        return a.endDate.getTime() - b.endDate.getTime();
    });

    var maxDate = tasks[tasks.length -1].endDate;
    tasks.sort(function(a,b) {
        return a.startDate.getTime() - b.startDate.getTime();
    });
    var minDate = tasks[0].startDate;

    var format = "%H:%M";
    var timeDomainString = "1day";

    var gantt = d3.gantt().taskTypes(taskNames).taskStatus(taskStatus).tickFormat(format).height(450).width(800);
    gantt.timeDomainMode("fixed");
    changeTimeDomain(timeDomainString);

    gantt(tasks);

    function changeTimeDomain(timeDomainString) {
        this.timeDomainString = timeDomainString;
        switch (timeDomainString) {
        case "1hr":
        format = "%H:%M:%S";
        gantt.timeDomain([ d3.time.hour.offset(new Date(getEndDate()), -1), getEndDate() ]);
        break;
        case "3hr":
        format = "%H:%M";
        gantt.timeDomain([ d3.time.hour.offset(new Date(getEndDate()), -3), getEndDate() ]);
        break;

        case "6hr":
        format = "%H:%M";
        gantt.timeDomain([ d3.time.hour.offset(new Date(getEndDate()), -6), getEndDate() ]);
        break;

        case "1day":
        format = "%H:%M";
        gantt.timeDomain([ d3.time.day.offset(new Date(getEndDate()), -1), getEndDate() ]);
        break;

        case "1week":
        format = "%a %H:%M";
        gantt.timeDomain([ d3.time.day.offset(new Date(getEndDate()), -7), getEndDate() ]);
        break;
        default:
        format = "%H:%M"

        }
        gantt.tickFormat(format);
        gantt.redraw(tasks);
    }

    function getEndDate() {
        var lastEndDate = Date.now();
        if (tasks.length > 0) {
            lastEndDate = tasks[tasks.length - 1].endDate.getTime();
        }
        return lastEndDate;
    }

}

我得到错误的地方是:

var gantt = d3.gantt().taskTypes(taskNames).taskStatus(taskStatus).tickFormat(format).height(450).width(800);

上面写着Property 'gantt' does not exist on type 'typeof d3'

我按如下所示导入d3

I import my d3 as follows

import * as d3 from 'd3';

我在其他任何地方都没有任何错误，我正在努力寻找问题所在.

I dont have any errors anywhere else and i am struggling to track down the issue.

有什么想法吗?

编辑

作为确保d3正常运行的测试，我实现了一个简单的圆，如下所示:

Also as a test to make sure d3 is working i implement a simple circle as follows:

d3.select("#scheduleDiv").append("svg").attr("width",50).attr("height", 50).append("circle").attr("cx", 25).attr("cy", 25).attr("r", 25).style("fill", "purple");

这可以正常工作，但.gantt()不能

This works fine but the .gantt() does not

推荐答案

您遇到了该错误，因为gantt()方法不属于d3库.它是从进口的 在您的示例中为<script type="text/javascript" src="http://static.mentful.com/gantt-chart-d3v2.js"> </script‌​>.

You are having that error because gantt() method is not part of the d3 library. It is imported from <script type="text/javascript" src="http://static.mentful.com/gantt-chart-d3v2.js"> </script‌​> in your example.

如果可以找到甘特库的定义文件，则可以添加它.如果没有，则必须创建一个自定义变量，例如:

If you can find the definition file of the gantt library you can add it. If not, you have to create a custom one like:

declare module d3 {
    export function gantt(input:any, input2:any): any;

}
