我目前正在使用Highcharts蜘蛛网图表,想知道我是否可以执行以下操作
答案 0 :(得分:1)
如何缩放极坐标图? (或者可能吗?)
如果你想要像zoomType
这样的缩放,那么没有。 zoomType
已针对极坐标图禁用highcharts-more.js
。来自:
// Disable certain features on angular and polar axes
chart.inverted = false;
chartOptions.chart.zoomType = null;
如何在每个细分中添加背景色?
您可以使用数学和Chart.renderer
创建和填充路径,为段的背景着色。例如,您可以这样做:
var colors = [ "pink", "yellow", "blue", "red", "green", "cyan", "teal", "indigo" ];
var parts = 6;
for(var i = 0; i < parts; i++) {
centerX = chart.plotLeft + chart.yAxis[0].center[0];
centerY = chart.plotTop + chart.yAxis[0].center[1];
axisLength = chart.yAxis[0].height;
angleOffset = -Math.PI/2;
angleSegment = Math.PI/(parts/2);
firstPointX = centerX + (axisLength * Math.cos(angleOffset + (angleSegment * i)));
firstPointY = centerY + (axisLength * Math.sin(angleOffset + (angleSegment * i)));
secondPointX = centerX + (axisLength * Math.cos(angleOffset + (angleSegment * (i+1))));
secondPointY = centerY + (axisLength * Math.sin(angleOffset + (angleSegment * (i+1))));
chart.renderer.path([
'M', centerX, centerY,
'L', firstPointX, firstPointY,
'L', secondPointX, secondPointY,
'Z'
]).attr({
fill: colors[i % colors.length],
'stroke-width': 1,
'opacity': 1
}).add();
}
如this JSFiddle demonstration所示。您只需要使用parts
变量匹配类别数。
