如何在 TikZ/pgfplot 中获取圆形 ytick 值？

Question

我是 TikZ/pgfplotting 的新手。我不明白为什么我得到的是这些x,xxx,999值而不是整数值。我尝试过多次x,xxx,000更改ymax,值但都失败了。也无济于事。我该怎么做才能完美地表示这些数据？yminytick={}

\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{arrows}
\usepackage{pgfplots}
\usepackage{import}

\pgfplotsset{compat=newest,
        scaled ticks=false,
            yticklabel style={
                   /pgf/number format/.cd,
                      fixed,
                     precision=0,
                    fixed zerofill,
            /tikz/.cd},
            every tick label/.append style={font=\small},
            }

\begin{figure}    
\begin{subfigure}[t]{0.48\linewidth}
\begin{tikzpicture}[scale=0.9]
\begin{axis}[
    legend style={font=\fontsize{7}{5}\selectfont},
    xtick={0,5,10,...,50},
    %ytick={2238000,2239000,...,2247000},
    xmin=0,
    xmax=50,
    ymin=2238000,
    ymax=2247000,
    xlabel=Trials (n) $\rightarrow$,
    ylabel=Total Cost (\$) $\rightarrow$,
    grid=both,
    minor grid style={gray!25},
    major grid style={gray!25},
    width=0.9\linewidth,]
\addplot[blue] table [x=a, y=c, col sep=comma] {./Datas/40_unit_50_trials.csv};
\addlegendentry{Total Costs at Trials}
\addplot[red] table [x=a, y=c, col sep=comma] {./Datas/avg_40_unit_50_trials.csv};
\addlegendentry{Average Total Cost}
\end{axis}
