Line sequence error

[JTCDCTWB]

In the code snippet below:

economics %>% 
  arrange(uempmed) %>% 
  plot_ly(x = ~date, y = ~uempmed, color = I("red"), type = "scatter", mode = "line+marker")

The line is not drawn based on the order of dates but rather in the order the data appears. The version of plotly being used is 4.10.4.

That is by design. If you want it ordered by x, you need add_lines()

Thank you very much for your answer. I have modified the code as follows:

economics %>% arrange(uempmed) %>% plot_ly(x = ~date, y = ~uempmed, name = "uempmed") %>% add_lines() %>% add_markers()

How do I combine the point and line legends into a single legend?
