Cannot convert Array{Any,2} to series data for plotting

Question

I am learning the Julia from the coursera

using DelimitedFiles
EVDdata = DelimitedFiles.readdlm("wikipediaEVDdatesconverted.csv", ',')

# extract the data
epidays = EVDdata[:,1]
EVDcasesbycountry = EVDdata[:, [4, 6, 8]]

# load Plots and plot them
using Plots
gr()
plot(epidays, EVDcasesbycountry)

I am getting the error message Cannot convert Array{Any,2} to series data for plotting but in that course the lecturer successfully plots the data. where I am going wrong?

I search about the error where I end up something call parsing the string into an integer. As the data set may contain string values.

Or am I missing something else.

Answer 1

I found this to be working for me:

# extract the data
epidays = Array{Integer}(EVDdata[:,1])
EVDcasesbycountry = Array{Integer}(EVDdata[:, [4, 6, 8]])

# load Plots and plot them
using Plots
gr()
plot(epidays, EVDcasesbycountry)
