Matplotlib图形对齐

Question

我试着在一场特殊的轮滑德比比赛中用图表表示得分和点球。本场比赛共有41次果酱，但并不是每一次果酱都会累积积分或点球。你知道吗

我想创建一个每队点球的条形图，覆盖一个每队得分的散点图。X轴是果酱，因为点球和分数来自同一场比赛，所以它们与相同的果酱号码有关。你知道吗

当我用两个图表创建一个图形时，x轴没有正确对齐。当条形图从果酱1开始时，散点图与果酱1在果酱3的某处对齐。你知道吗

Inaccurate Double Graph

当我分别查看每个图时，散点图在第一次阻塞之前有一个缩进，但条形图紧靠y轴。你知道吗

下面是我用来创建图表的代码：

fig, ax=plt.subplots (figsize=(15,8) )
sns.barplot(x="jam_number", y="name" , hue="team_name", data=df1 )

ax.legend(title="Team Name")
ax.set_yticks([0, 1, 2, 3, 4])
ax.set(xlabel='Jam Number', ylabel='Penalties/Points')
ax2 = ax.twinx()
ax2.scatter(x=DJPoints["jam_id"], y=DJPoints["points"], color="blue")
ax2.scatter(x=GJPoints["jam_id"], y=GJPoints["points"], color="red")
