Use xanchor = 'left' with x value less than 0.

library(plotly)

tit <- list(
  text = ttl,
  font = chrt_title,
  xref = "paper",
  yref = "paper",
  xanchor = "left",
  x = -0.04,
  y = 1,
  showarrow = FALSE
)


chart <- g %>% layout(annotations = tit,
                      xaxis = ax,
                      yaxis = list (title = " "),
                      font=chrt_title, showline = TRUE)
