dataLabels.format问题

[githeer]

com.github.aachartmodel.aainfographics.demo I/chromium: [INFO:CONSOLE(1)] "Uncaught SyntaxError: Unexpected token h in JSON at position 474", source: file:///android_asset/AAChartView.html (1)

val formatStr = 
"<img src=\"https://www.highcharts.com/samples/graphics/sun.png\">" +
"<span style=\"color:#FFFFFF;font-weight:thin;font-size:25px\">{y}</span>" +
"<span style=\"color:#FFFFFF;font-weight:thin;font-size:17px\"> m</span>"

demo中或者是自己自定义样式，都会报错，android版本不行，iOS没问题
