, show, how to do? Insert the following code:var wx = d3.scale.linear () . Domain ([0, D3.max (DataSet)]) . Range ([0,500]);D3.scale.linear () is used to generate a scale bar of a linear function whose initial definition domain is [0, 1], the initial range range is [0, 1], where [] represents the scope. Now we set domain to [0,
