Excuse me: render the chart function drowEchart () for the on which or the request data initialization function getData () for the in where?


I render every chart data is empty

CodePudding user response:

To get the data function is the delay, you put the rendering echat function in access to data in the callback function

This, getData (). Then (res=& gt; Enclosing drowEchart ())

CodePudding user response:

Why no error and no data chart didn't render out

CodePudding user response:

Your getData is network request, the request data in the getData successfully and for the corresponding variable assignment, call drowEchart again

CodePudding user response:

Is the network request you mean in the getData call drowEchart?

CodePudding user response:

The getData method request callback calls drowEchart success

My idea is just a request to get behind several graphing data sources are from the data () to get it without a request a render every chart
But because I have a different chart rendering data is that a request to the inside can't don't know this
