Logscale for Y-axes works for gr() but not for pyplot()

Here is the code for gr()

using Plots

gr()

function getLogTicks(vector,count=1)
    function poststr(expnum)
        n = Int64(expnum) ÷ 3
        if n == 0
            return ""
        elseif n == 1
            return "k"
        else
            return "×\$10^{$(n*3)}\$"
        end
    end
    min = ceil(log10(minimum(vector)))
    max = floor(log10(maximum(vector)))
    major = [ [k*n for k = 1:count] for n in 10 .^ collect(min:max) ]
    major = hcat(major...)
    major = vec(major)
    major = filter(x->x<=maximum(vector),major)
    majorText = ["$(Int64(j*10^(i%3)))$(poststr(i))" for i=min:max for j=1:count]
    majorText = majorText[1:length(major)]
    minor = [j*10^i for i=(min-1):(max+1) for j=(count+1):9]
    minor = minor[findall(minimum(vector) .<= minor .<= maximum(vector))]
    ([major; minor], [majorText; fill("", length(minor))])
end

yticks_scale = getLogTicks( collect(1:2000) )

plot(1:2000,1:2000,yaxis=:log10, yticks=yticks_scale)

with the resultant graph

But when I change it from “gr()” to “pyplot()”, I get the following

using Plots

pyplot()

function getLogTicks(vector,count=1)
    function poststr(expnum)
        n = Int64(expnum) ÷ 3
        if n == 0
            return ""
        elseif n == 1
            return "k"
        else
            return "×\$10^{$(n*3)}\$"
        end
    end
    min = ceil(log10(minimum(vector)))
    max = floor(log10(maximum(vector)))
    major = [ [k*n for k = 1:count] for n in 10 .^ collect(min:max) ]
    major = hcat(major...)
    major = vec(major)
    major = filter(x->x<=maximum(vector),major)
    majorText = ["$(Int64(j*10^(i%3)))$(poststr(i))" for i=min:max for j=1:count]
    majorText = majorText[1:length(major)]
    minor = [j*10^i for i=(min-1):(max+1) for j=(count+1):9]
    minor = minor[findall(minimum(vector) .<= minor .<= maximum(vector))]
    ([major; minor], [majorText; fill("", length(minor))])
end

yticks_scale = getLogTicks( collect(1:2000) )

plot(1:2000,1:2000,yaxis=:log10, yticks=yticks_scale)

with the resultant graph

What did I do wrong?
