ChartJS雷达尺度点

Question

我有一个雷达图表(几乎)显示我想要它.唯一的问题是比例应该达到20,但正如你在下面看到的那样,突出显示的点是17并且不在图表之内.如何缩放它以使最大点为20并且显示的突出显示点将在图表内？

我目前的代码是:

var radarChartData = {
    labels: ["ATT", "SPD", "POW", "DEF", "STA", "TEC"],
    datasets: [ {
        scaleOverride: true,
        scaleSteps: 5,
        scaleStepWidth: 5,
        scaleStartValue: 0,
        pointLabelFontSize: 16,
        fillColor: "rgba(0,120,0,0.2)",
        strokeColor: "rgba(0,120,0,1)",
        pointColor: "rgba(10,10,10,1)",
        pointStrokeColor: "#ccc",
        pointHighlightFill: "#333",
        pointHighlightStroke: "rgba(255,255,0,1)",
        data: [12,15,17,16,11,13] 
    } ] 
};

我认为这将是scaleSteps,scaleStepWidth并且scaleStartValue将改变这个选项,但似乎并没有影响到它.

编辑:它似乎不影响另一组数据......

正如您在此处所看到的,17的值确实位于图表中.这个代码是:

var radarChartData = {
    labels: ["ATT", "SPD", "POW", "DEF", "STA", "TEC"],
    datasets: [ {
        scaleOverride: true,
        scaleSteps: 5,
        scaleStepWidth: 5,
        scaleStartValue: 0,
        pointLabelFontSize: 16,
        fillColor: "rgba(0,120,0,0.2)",
        strokeColor: "rgba(0,120,0,1)",
        pointColor: "rgba(10,10,10,1)",
        pointStrokeColor: "#ccc",
        pointHighlightFill: "#333",
        pointHighlightStroke: "rgba(255,255,0,1)",
        data: [19,17,15,6,16,15] 
    } ] 
};

2之间有什么区别？第二个值为19,ATT但它在图表中就好了.

好吧,我想通了,我需要移动scaleSteps,scaleStepWidth并scaleStart以新的申报Radar表作为下面,而不是在数据集.

window.onload = function(){
var ctx = document.getElementById("radarCanvas").getContext("2d");
window.myRadar = new Chart(ctx).Radar(radarChartData, {
responsive: false,
    pointDot:false,
    showTooltips: false,
    scaleOverride: true,
    scaleSteps: 4,
    scaleStepWidth: 5,
    scaleStartValue: 0
}); }
