I want to plot selected data from rows and columns

I have data in a table and i want to plot first column (row 256 to 345) as X against second column (row 256 to 345) as Y. I need help

Answer 1

[Torsten]

Plotting the second against the first column does not make much sense because the first column is the year and the second column is the month of the year, but here we go:

A = readmatrix("https://de.mathworks.com/matlabcentral/answers/uploaded_files/1186758/SN_m_tot_V2.0.txt");
plot(A(256:345,1),A(256:345,2))

Answer 2

T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1186758/SN_m_tot_V2.0.txt') ;
scatter3(T.(1),T.(2),T.(3),[],T.(3))

Let me use the ulr info like @KSSV @Torsten did!!

Here you are:

data = readtable("https://www.mathworks.com/matlabcentral/answers/uploaded_files/1186758/SN_m_tot_V2.0.txt")

data = 3286×7 table
    Var1    Var2     Var3     Var4     Var5    Var6       Var7   
    ____    ____    ______    _____    ____    ____    __________

    1749      1       1749     96.7     -1      -1     {0×0 char}
    1749      2     1749.1    104.3     -1      -1     {0×0 char}
    1749      3     1749.2    116.7     -1      -1     {0×0 char}

    1749      5     1749.4    141.7     -1      -1     {0×0 char}
    1749      6     1749.5    139.2     -1      -1     {0×0 char}
    1749      7     1749.5      158     -1      -1     {0×0 char}
    1749      8     1749.6    110.5     -1      -1     {0×0 char}
    1749      9     1749.7    126.5     -1      -1     {0×0 char}
    1749     10     1749.8    125.8     -1      -1     {0×0 char}
    1749     11     1749.9    264.3     -1      -1     {0×0 char}
    1749     12       1750      142     -1      -1     {0×0 char}
    1750      1       1750    122.2     -1      -1     {0×0 char}
    1750      2     1750.1    126.5     -1      -1     {0×0 char}
    1750      3     1750.2    148.7     -1      -1     {0×0 char}
    1750      4     1750.3    147.2     -1      -1     {0×0 char}

plot(data.Var1(256:345),data.Var2(256:345))

Change the names of the variables as appropriate please.
