How to scatter plot when the values are i.e 1,1 and 1,10 grid

trying to avoid repeating code

plot(sparams.frequency_GHz(1),delta(:,1))

plot(sparams.frequency_GHz(41),delta(:,1))

and for this when i try doing the same it does not work , possible to combine ??

plot(sparams.frequency_GHz(:,1),delta(:,2:end), plot_color,'HandleVisibility','off')

[Kevin Holly]

Is sparams a table or struct array? How many rows and columns are there for frequency_GHz data? rows and columns for delta?

[Ihaveaquest]

struct array

both

Freq 41X16

delta 41x16

Answer 1

What do you want on your y and x axes?

sparams.frequency_GHz = 10*rand(41,16);
delta = rand(41,16);

This one separates the data based on the columns (16 groups)

scatter(sparams.frequency_GHz,delta,'filled')
xlabel('Frequency (GHz')
ylabel('Delta')

This one separates the data based on the rows (41 groups)

scatter(sparams.frequency_GHz',delta','filled')
xlabel('Frequency (GHz')
ylabel('Delta')

so in my variable frequency i have 1-10 but i only need to plot variables at 1 and 10

Are you saying there are 10 possible frequency values in the 41x16 matrix?

sparams.frequency_GHz = randi(10,41,16);
sparams.frequency_GHz

ans = 41×16

10 8 8 1 10 2 6 1 2 5 8 6 6 6 8 8 3 6 3 6 7 5 4 2 1 9 1 5 1 3 7 6 9 9 9 2 9 3 2 7 2 5 4 1 5 8 8 3 8 5 1 4 10 10 4 7 6 9 6 8 5 4 2 1 10 6 8 3 8 7 9 2 8 8 4 8 3 5 6 4 7 3 5 3 9 5 4 4 1 6 6 5 1 10 1 10 3 6 1 3 2 9 10 9 8 4 4 5 4 4 4 7 6 4 1 10 2 5 2 6 7 3 10 3 6 6 7 1 8 3 1 4 2 7 1 8 10 1 1 9 3 7 5 1 4 7 5 2 10 6 5 5 8 10 7 10 2 9 10 9

delta = rand(41,16);

Create logical array when freq equals 1 or 10.

 At_one = sparams.frequency_GHz==1;
 At_ten = sparams.frequency_GHz==10;
 At_one_ten = logical(At_one + At_ten)

At_one_ten = 41×16 logical array
