我有由正值和負值組成的數據，這些數據將顯示在圖表中。我試圖以正值的數據點大于負值的數據點的方式顯示數據。以下是我的代碼<html> <head><script src="http://code.highcharts.com/highcharts.js"></script><script src="http://code.highcharts.com/modules/exporting.js"></script> <script src="https://code.jquery.com/jquery-3.1.1.min.js"></script> </head> <body> <div id="demochart"></div> <button id="update"> Update</button> <script> Highcharts.chart('demochart', { chart: { type: 'scatter' }, xAxis: { categories: [0, 10, 20, 30, 40, 50, 60, 70, 80] }, series: [{ name: 'Temperature', data: [15, 50, -56.5, -46.5, -22.1, -2.5, -27.7, -55.7, 76.5] }] },function(chart){ $('#update').click(function(){ var data = chart.series[0].data; var new_array = []; new_array = data; console.log(new_array); for(var i = 0; i < new_array.length; i++){ console.log("For: "+ new_array[i].y); if(new_array[i].y > 0){ new_array[i].y = "{y:"+ new_array[i] +",marker: {radius: 10}}" console.log("If: "+ new_array[i].y); }else{ new_array[i].y = "{y:"+ new_array[i] +",marker: {radius: 4}}" console.log("Else: "+ new_array[i].y); } } chart.series[0].setData(new_array); }) });</script> </body></html>當我單擊更新按鈕時，必須更改數據點值半徑的大小。這種情況能行嗎？
如何根據數據更改高圖表半徑
