使用传统方法时，绘图标题不会显示在两行上

Question

乍一看，这很简单，但我已经使用了我找到的解决方案here，但它并不适合我。

以下是我用于剧情的代码：

# interactive plot with ribbon
test <- ggplot(data = wide.data, aes(x = Games, y = Prediction)) +
  geom_ribbon(aes(ymin = Lower, ymax = Upper, fill = League), alpha = .5) + 
  geom_point() + 
  labs(x = "Number of Games Played", y = "Total Number of Goals") + scale_y_continuous(breaks=seq(0,70,5)) +
  scale_x_continuous(breaks=seq(0,50,5)) + theme_light() +
  labs(title = 'Prediction lines and Confidence Intervals \n for Six Leagues') + 
  theme(plot.title = element_text(size = 15)) +
  theme(plot.title = element_text(hjust = 0.5))

ggplotly(test)

我错过了一些明显的东西吗？对不起，如果这不是一个特别有用的问题。

编辑：添加以下数据源：

> dput(wide.data)
