Dear all,

I have set the color of bar to red ,but I always get the color of grey. What’s wrong with this problem?

using DataFrames
using CSV
using Plots
using PlotThemes

df = DataFrame(CSV.File("gdp.csv", header=true))
sort!(df, :Year)

theme(:dark)
p = bar(df.Year, zeros(nrow(df)), ylim=(0, maximum(df.GDP)),
    leg=false, xlabel="Year", ylabel="GDP", c=:white)

anim = Animation()

for x in range(1, nrow(df), step=1)
    bar!(p, [df.Year[x]], [df.GDP[x]], c = :red)
    frame(anim)
end

gif(anim, "gdp.gif", fps = 15)

gdp

The correct argument is color, not c.

    bar!(p, [df.Year[x]], [df.GDP[x]], color = :red)

It does not work. The color is still grey.

Humpf. I got one glorious all red plot the first time I tried. Now I get one red bar and the rest white with either c or color.

What versions are you using?

(dfenv) pkg> st
      Status `~/Desktop/Julia/dfenv/Project.toml`
  [336ed68f] CSV v0.10.4
  [a93c6f00] DataFrames v1.3.4
  [ccf2f8ad] PlotThemes v3.0.0
  [91a5bcdd] Plots v1.29.0

Plotting one at a time in the REPL gets the correct red bars, using @animate or frame like this example always results in a .gif with the first bar red and the rest white. I am stumped, sorry.

The problem is solved. Maybe it’s the problem of Vscode. Now It display the correct color. Thanks for your help.
