Chart.jsのレーダーチャートのオプション

JavaScript Web

なんか最近流行ってますね。

参考:Chart.js | HTML5 Charts for your website.

ちょっと最近使う用事があったときに、オプションで戸惑ったのでそのメモを。
ちなみに、レーダーチャートのやつです。

Radar.defaults = {
				
	//Boolean - If we show the scale above the chart data			
	scaleOverlay : false,
	
	//Boolean - If we want to override with a hard coded scale
	scaleOverride : false,
	
	//** Required if scaleOverride is true **
	//Number - The number of steps in a hard coded scale
	scaleSteps : null,
	//Number - The value jump in the hard coded scale
	scaleStepWidth : null,
	//Number - The centre starting value
	scaleStartValue : null,
	
	//Boolean - Whether to show lines for each scale point
	scaleShowLine : true,

	//String - Colour of the scale line	
	scaleLineColor : "rgba(0,0,0,.1)",

	scaleLineWidth : 1,

	//Boolean - Whether to show labels on the scale	
	scaleShowLabels : false,
	
	//Interpolated JS string - can access value

	//Boolean - Whether we show the angle lines out of the radar
	angleShowLineOut : true,
	
	//String - Colour of the angle line
	angleLineColor : "rgba(0,0,0,.1)",

}

使ったやつのメモ

that.OPTIONS = {
	scaleShowLine: false, // 区切りの表示
	scaleLineWidth : 1, // 区切りの太さ(px)
	scaleOverride: true, // 区切りを絶対値で指定
	scaleSteps : 5, // 区切りの数
	scaleStepWidth : 20, // 区切りの間隔(100%がMAXのグラフなら、100/scaleSteps)
	scaleStartValue : 0, // 区切りの開始値(100%がMAXのグラフなら、0%の0)
	animation : false, // 表示時のアニメーションの有無
	pointDot: false, // 頂点に丸を打つか
	pointLabelFontStyle: '900', // 各項目名のスタイル類
	pointLabelFontSize: 13,
	pointLabelFontColor: '#5b4f30'
};

めもめも。
