这种是回归的问题，还是图没画好呢？我的stata代码是：marginsplot, xlabel(`low_c_industry_novelty1' "Low novelty" `high_c_industry_novelty1' "High novelty") ytitle("award level") ///    ylabel(0(0.02)0.3, angle(0) nogrid) ///
    yscale(range(0 0.3)) ///
    graphregion(color(white)) ///
    plotregion(margin(l+8 r+8)) ///
    legend(order(1 "Low cooperation" 2 "High cooperation") size(small) col(1) position(11) ring(0) region(fcolor(none) lpattern(blank))) ///
    title("Marginal effects of industry novelty on award level at different levels of cooperation") noci
