a <- list(
text = "Data 1",
font = f,
xref = "paper",
yref = "paper",
yanchor = "bottom",
xanchor = "center",
align = "center",
x = 0.5,
y = 1,
showarrow = FALSE
)
b <- list(
text = "Data 2",
font = f,
xref = "paper",
yref = "paper",
yanchor = "bottom",
xanchor = "center",
align = "center",
x = 0.5,
y = 1,
showarrow = FALSE
)
pl.1 <- plot_ly(x=~df.1$x,y=~df.1$y,type='scatter',mode='lines',line=list(color="#A9A9A9")) %>%
layout(xaxis=list(title="Count",zeroline=F),yaxis=list(title="Density",zeroline=F)) %>%
layout(annotations = a)
pl.2 <- plot_ly(x=~df.2$x,y=~df.2$y,type='scatter',mode='lines',line=list(color="#A9A9A9")) %>%
layout(xaxis=list(title="Count",zeroline=F),yaxis=list(title="Density",zeroline=F)) %>%
layout(annotations = b)
subplot(list(pl.1,pl.2),nrows=1,shareX=F,shareY=F,titleX=T,titleY=T) %>% layout(showlegend=F)
