has been resolved because I used location, which caused some problems
as shown in figure 1, the width of my father"s box .dt _ depth is 33%, which is parsed as 378px

echarts.lin_box .dt_depthwidth:100%body
ech100%
the current problem is that the width of my echarts is the width of the full screen, not the width of the parent element. There is a problem with the display on the page
