D3 V4 gallery library implementation with dependencies

FunDeckHermit — Thu, 22 Mar 2018 10:43:21 GMT

Hello everyone,

I'm trying to implement an example library from the D3 gallery called Visavail. A demo of this library can be found here: link.

I'm having difficulties getting it to work, any help or pointers will be appriciated.

Setup:

Installed Moment with npm
Installed D3 V4 with npm
Added Visavail library to the node_modules folder
Added font-awesome tot the style folder

Then I referenced it all in pbiviz.json:

  "externalJS": [
    "node_modules/powerbi-visuals-utils-dataviewutils/lib/index.js",
	  "node_modules/d3/build/d3.min.js",
    "node_modules/visavail/js/visavail.js",
    "node_modules/moment/min/moment-with-locales.min.js"
  ],
  "style": "style/visual.less",
  "capabilities": "capabilities.json",
  "dependencies": "dependencies.json",
  "stringResources": []

The CSS was referenced in the visual.less file:

@import (less) "style/font-awesome/css/font-awesome.min.css";
@import (less) "node_modules/visavail/css/visavail.css";

The code:

In Visual.ts, based on the hello world update counter I recreated the Visavail example with static data.

module powerbi.extensibility.visual {
    "use strict";
    export class Visual implements IVisual {
        private target: HTMLElement;
        private settings: VisualSettings;

        private d3;
        private visavail;
        private moment;
        private svg;
        private mydataset;
        private chart;

        constructor(options: VisualConstructorOptions) {
            console.log('Visual constructor', options);
            this.target = options.element;
            
            this.d3 = (window as any).d3;
            this.visavail = (window as any).visavail;
            this.moment = (window as any).moment;

            this.moment.locale("en");

            this.svg = this.d3.select(this.target).append('svg');

        }

        public update(options: VisualUpdateOptions) {
            this.settings = Visual.parseSettings(options && options.dataViews && options.dataViews[0]);
            this.target.innerHTML = '<p id="example">TEST</em></p>';
            
            this.chart = this.visavail.visavailChart().width(800);

            this.mydataset = [{
                "measure": "Annual Report", 
                "data": [
                    ["2015-01-01", 0, "2015-03-04"],
                    ["2016-01-01", 1, "2016-03-03"],
                    ["2017-01-01", 1, "2017-03-06"],
                    ["2018-01-01", 1, "2018-04-01"]
                ]
            }];

            this.d3.select("#example").datum(this.mydataset).call(this.chart);
        }

        private static parseSettings(dataView: DataView): VisualSettings {
            return VisualSettings.parse(dataView) as VisualSettings;
        }

        public enumerateObjectInstances(options: EnumerateVisualObjectInstancesOptions): VisualObjectInstance[] | VisualObjectInstanceEnumerationObject {
            return VisualSettings.enumerateObjectInstances(this.settings || VisualSettings.getDefault(), options);
        }
    }
}

Am I referencing the dependencies correctly?
Am I importing the dependencies correctly?
Am I implementing the dependencies correctly?
How do I debug this?

I zipped the entire project, it can be downloaded here:

Hello FunDeckHermit,

The chart didn't work due to using d3v4 instead of d3v3. We installed d3v3 and created the global injector for moment to fix this visual.

Please find the fixed source code here.

Thank you!

With the implementation of the globalinjector, do you happen to know how to change the locale of moment.js?

I tried:

calling moment.locale("de") in the momentGlobalInjector.js
calling this.moment.locale("de") in the visual.ts
changing "/moment/min/moment-with-locales.min.js" to "/moment/locale/de.js
