将条形图中条形的左边缘与 x 值对齐，而不是中间

Question

我怎样才能将条形图的左侧与它们“分配”的 x 值对齐？

在我的条形图中，第一个条形与 y 轴重叠，但我希望它位于 y 轴的右侧。

因此，对于所有条形图，它们的中心不是与相应的 x 值对齐，而是它们的左边缘对齐。

我怎么做？

\begin{tikzpicture}
    \begin{axis}[
        axis lines = center,
        axis line style = {-},
        xlabel = $$,
        ylabel = $$,
        xmin = 0,
        xmax = 0.001,
        clip=false,
        xtick = {0, 0.001},
        xticklabels = {,},
        ymin = -1,
        ymax = 1,
        ytick = {-1,0,1},
        height = 10em,
        width = 30em,
      ]
      \addplot [
        ybar,
        fill=blue,
        bar width=0.000005,
        draw=none,
      ]
      coordinates {
        (0,0.00928)
        (0.00002083333,0.23672)
        (0.00004166667,0.31467)
        (0.0000625,0.58179)
        (0.00008333333,0.46774)
        (0.0001041667,0.71017)
        (0.000125,0.45074)
    };
  \end{axis}
\end{tikzpicture}

Answer 1

默认情况下，您会得到以 x 坐标为中心的条形图，但可以使用参数进行修改bar shift。您只需设置bar shift=0.0000025，即一半bar width。
