figure 1 is hchart, figure 2 is echart, their maximum value is 2, but the processing such as hchart is obviously better than echart, I would like to ask if you do not know the maximum value (cannot set the maximum value because the data is uncertain), how can echart set properties like hchart to leave a blank on the maximum value? Or the plug-in comes with it and cannot be set.
God of trouble, take a look. Thank you.
thanks for the invitation.
first of all, there can be no uncertain data.
in the moment you are about to draw, you must have got the exact data
the question can be translated into how to find the maximum
assume that the data obtained from the interface is similar
const res = {
code:0,
message:"success",
data:[
// 01
[1533698210801,20],
[1533698212822,30],
[1533698230844,10],
[1533698233901,50],
[1533698236780,20],
]
};
//
const values = res.data.map(([,v])=>v);
//
const max = Math.max(...values);
// option, 
you write
max: function(value) {
/*20%*/
return value.max * 1.2;
}I wish I could
option = { xAxis: { type: category , data: [ Mon , Tue , Wed , Thu , Fri , Sat , Sun ] }, yAxis: { type: value }, series: [{ data: [120, 200, 150, 80, 70, 110, 130], type: bar , itemStyle:{ ...
