Hello Everyone, as you see from my grap, my y axis is not sorted. How can I sort the y axix from minumum to maximum.
```julia
using Plots
using DataFrames
using CSV
df = CSV.read("D:/ölçüm.csv", DataFrame)
Zaman2_1 = df[:, 1]
Sensor1_Z_ekseni_grafik2_1 = df[:, 5]
fig_ölçüm_iki = plot(Zaman2_1, Sensor1_Z_ekseni_grafik2_1, yticks=true, size = (1600,800), title = "Z ekseni Grafik Line", yflip=false, xlabel="Zaman", ylabel="Z (Gs)")
```

Hi, and welcome to the Julia community!
* * *
Note that you can enclose your code in triple backticks (```), for proper formatting. See also [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757).

Considering the x-axis uses a decimal point and the y-axis a decimal comma, my guess is your `df[:, 5]` is parsed as a `Vector{String}`. If so, you could convert it to a `Vector{Float64}` using `parse.(Float64, replace.(df[:, 5], ',' => "."))`, which will first replace every (decimal) comma by a (decimal) point, and then convert all these `String`s to `Float64`.
Once your y-values are floats, the y-axis should behave as you’d expect.

If this is because you are in a country that uses `,` as the decimal separator you can tell CSV about this. From the docstring:
```julia
decimal='.': a Char indicating how decimals are separated in floats, i.e. 3.14 uses '.', or 3,14 uses a comma ','
```
so
```julia
df = CSV.read(“D:/ölçüm.csv”, DataFrame; decimal = `,`)
```
will read `1.234,56` as `1234.56`.

I got this error after I applied that code. Do I miss anything here?

All your columns are strings now, so it doesn’t look like this was the right decimal separator. I don’t have your csv file, so it’s hard to say what’s going wrong.

I corrected the formatting of your post. Note that a backquote ``` is not the same as a quote `'` and the triple backquote must be on a line by itself.
