Hi @empet, thank you very much for your quick reply. I could never get close to your solution, no way. It works very well.
In the meantime, I was desperately trying to come up with a way of solving the problem. I found a workaround that works as well, certainly a bit clumsy. It takes one more step than in your code. I have to covert an array of Date types (named as “Quarters”) in “my_df” into an array of strings:
my_strings = my_df[!,:Quarters] = string.(my_df[:,:Quarters])
Then I applied the same logic in the docs’s example, using the strings to define the rectangles I want.
my_strings = my_df[!,:Quarters] = string.(my_df[:,:Quarters]) # Date type into strings
period10_5 = QuarterlyDate(1960, 1):Quarter(1):QuarterlyDate(2021,1)
y1 = randn(length(period10_5))
y2 = rand(length(period10_5))
trace00 = scatter(;x = Date.(period10_5), y = y1,
name = "Shrek", mode="markers+lines",
marker_symbol="circle", marker_size="5",line_width= 0.3,
marker_color = "Blue")
trace01 = scatter(;x = Date.(period10_5), y = y2,
name = "Murphy", mode="markers+lines",
marker_symbol="circle", marker_size="5",line_width= 0.3,
marker_color = "Red")
shapes = rect(["1962-07-01", "2010-07-01"], ["1970-01-01", "2018-01-01"],
0, 1; fillcolor = "gray", opacity = 0.2, line_width = 0,
xref = my_strings, yref = "paper")
layout00 = Layout(; title_text = "Shapes, my shapes", title_x = 0.5,
shapes = shapes,
annotations = [attr(x = "1966-07-01", y = 2.5, showarrow = false,
text = "QE1"),
attr(x = "2014-03-01", y = 2.5, showarrow = false,
text = "QE2") ],
xaxis = attr(
title = "Quarterly obervations",
tickformat = "%Y",
hoverformat = "%Y-Q%q",
tick0 = "1960/01/01",
dtick = "M120"),
#xaxis_range = [1960, 2020],
yaxis_title = "Percentage points",
#yaxis_range=[-2, 2],
titlefont_size = 16)
plot([trace00, trace01], layout00)
The plot looks like this:
Thanks a lot.
