[英]R Plotly add image watermark
I would like to have an image/watermark added to a double y-axis plot, somehow my code doesnt work..... How is this possible?我想将图像/水印添加到双 y 轴 plot,不知何故我的代码不起作用.....这怎么可能? It doesnt error but the image is not added它没有错误,但没有添加图像
df <- data.frame(x = 1:50,
y1 = c(20:5,6:10,9:3,4:20, 19:15),
y2 = c(100:115,200:204,50:44,4:20, 66:62))
And my code还有我的代码
plot_ly(df) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test",
x = ~x, y = ~y1,
line = list(color = '#999999'),
hoverinfo = "text",
text = ~paste(round(y1, 1), x)) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test", yaxis = 'y2',
x = ~x, y = ~y2,
line = list(color = '#CC79A7'),
hoverinfo = "text",
text = ~paste(round(y2, 1), x)) %>%
#layout
layout(title = "test",
xaxis = list(titel = "Date",
rangeslider = list(thickness = 0.05)),
yaxis = list(side = 'left', title = 'test',
showgrid = F, zeroline = F, type = "log",
showline = T),
images = list(source = "https://rstudio.com/wp-content/uploads/2018/10/RStudio-Logo.png",
xref = "paper",
yref = "paper",
xanchor = "left",
yanchor = "bottom",
x= 4,
y=4,
sizex = 5,
sizey = 5,
opacity = 0.8),
yaxis2 = list(side = 'right', overlaying = "y",
title = 'test',
showgrid = F, zeroline = F,
showline = T))
The problem is that you have no access to the Rstduio-logo.png.问题是您无权访问 Rstduio-logo.png。
layout(images = list(source = "test.png"))
