Alignment of ggtitle

First off, thank you for an incredible set of packages!

I'm facing an issue where the ggplot2 title aesthetics are not translated through ggplotyl(); more precisely, the horizontal title adjustment theme(plot.title = element_text(hjust = 0)) is ignored.

Code below:

library(ggthemes)
library(plotly)

set.seed(12345)
v <- runif(100, min=0, max=100)
df <- as.data.frame(v)
names(df) <- c("pressure")

t <- ggplot(df, aes(x = pressure)) +
  geom_histogram(bins = 20, alpha = 0.7, position = "identity") +
  scale_fill_fivethirtyeight(label = comma) +
  theme_tufte(base_size = 7, base_family = "Avenir") +
  labs(x =  "pressure", "# observations", title = "pressure plot") +
  theme(plot.title = element_text(hjust = 0)) +
  theme(axis.ticks = element_blank()) +
  scale_x_continuous()
(gg <- ggplotly(t))

Is there another way to define the location of text elements? Thanks!

首先运行提供的 R 示例，并检查生成的 ggplotly 标题的对齐方式是否符合 ggplot2 主题设置。跟踪标题的水平调整是如何转换的，然后验证渲染后的标题遵循 hjust = 0，同时不破坏标题的其他定位方式。
