but when i use the chartView con , I like that, i try to use 'this.state.dataY' to show the series[0].data, it not work, but data like this '[1,2,3,4]' , it work well, 'this.state.dataX' in xAxis.categories works well too,
so, I donot know how to update the datas when i get the responseDate from fetch,
it is my first time to write the issues in github and also first time writing in english,,,
'this.state.dataX' and 'this.state.dataY' the the right data,
