# newline-echarts

###Introduce

許多人使用百度的echarts.js時候會出現資料名太長覆蓋的情況，newline-echarts.js能夠很好解決這種換行問題


###Usage

newline(option, 6, 'yAxis')
* 引數一：是你的option
* 引數二：是多少個字就換行
* 引數三：是x軸還是y軸 可選項 'yAxis' OR 'xAxis'
var chart = echarts.init(document.getElementById("main"));
<script src="js/echarts.js"></script>
var option = 
{
    # your options
}

option = newline(option, 6, 'yAxis')
chart.setOption(option)
