Plotting a matrix of line plots

Hi!

I have to plot multiple line plots in a matrix. So for example, consider that I have 2 variables x and y and I have 3 data sets of each, i.e x1y1 x2y2 x3y3.

I need to plot this data in a matrix form of 6x6, i.e 36 individual graphs. There's an image of the expected graph below. Any help is much appreciated!

What are the dimensions of each? Attach your data.

[Manas Pratap]

Attaching the data below, Each column reperesents one variable of data.

[KSSV]

The data is scattered data. What do you expect? You want multiple lines as shown in the attched image?

[Manas Pratap]

Yeah, the first column of book 1 corresponds to the first column of book2 and so on

Did you try calling subplot() a bunch of times like I showed you below? You can also call nexttile().

[Manas Pratap]

The x and y axis should only come up on the sides of the entire image, not individually for each plot

@Manas Pratap, did you see my second answer where I turned off those axes?

Answer 1

[KSSV]

x1 = rand ; y1 = rand;
x2 = rand ; y2 = rand ;
x3 = rand ; y3 = rand ;
[X,Y] = meshgrid([x1 y1 x2 y2 x3 y3]) ;

[Manas Pratap]

It didnt plot anything..

[KSSV]

plot(X,Y,'k',X',Y','k')

Try subplot(). Adapt as needed.

numPoints = 10;
v1 = sort(rand(1, numPoints));
v2 = sort(rand(1, numPoints));
v3 = sort(rand(1, numPoints));
v4 = sort(rand(1, numPoints));
v5 = sort(rand(1, numPoints));
v6 = sort(rand(1, numPoints));
% Concatenate
v = {v1;v2;v3;v4;v5;v6}
rows = numel(v)
for k1 = 1 : rows
    for k2 = 1 : rows
        thisx = v{k1};
        thisy = v{k2};
        subplot(rows, rows, rows*(k1-1)+k2)
        plot(thisx, thisy, 'b-', 'Linewidth', 2)
        grid on;
        drawnow;
    end
end

Answer 3

[Yusuf Suer Erdem]

x1 = rand; y1 = rand;

x2 = rand; y2 = rand;

x3 = rand; y3 = rand;

[X,Y] = meshgrid([x1 y1 x2 y2 x3 y3]);

plot(X,Y)

Add plot(X,Y) command below it.

@Manas Pratap since you said in a comment "The x and y axis should only come up on the sides of the entire image, not individually for each plot", you can turn the tick marks off except in the first column or last row:

numPoints = 10;
v1 = sort(rand(1, numPoints));
v2 = sort(rand(1, numPoints));
v3 = sort(rand(1, numPoints));
v4 = sort(rand(1, numPoints));
v5 = sort(rand(1, numPoints));
v6 = sort(rand(1, numPoints));
% Concatenate
v = {v1;v2;v3;v4;v5;v6}
rows = numel(v)
for k1 = 1 : rows
    for k2 = 1 : rows
        thisx = v{k1};
        thisy = v{k2};
        subplot(rows, rows, rows*(k1-1)+k2)
        plot(thisx, thisy, 'b-', 'Linewidth', 2)
        grid on;
        drawnow;
        % Turn off y axis except if it's the first column.
        if k2 > 1
            yticks([]);
        end
        % Turn off x axis except if it's the last row.
        if k1 < rows
            xticks([]);
        end
    end
end

I think I misunderstood my question. I have 6 datasets, I have to plot a scatter plot matrix of them. So basically when x1 aligns with x1 i get a graph but when x1 aligns with x2 i get a scatter plot..

[Image Analyst]

numPoints = 10;
v1 = sort(rand(1, numPoints));
v2 = sort(rand(1, numPoints));
v3 = sort(rand(1, numPoints));
v4 = sort(rand(1, numPoints));
v5 = sort(rand(1, numPoints));
v6 = sort(rand(1, numPoints));
% Concatenate
v = {v1;v2;v3;v4;v5;v6}
rows = numel(v)
for k1 = 1 : rows
    for k2 = 1 : rows
        thisx = v{k1};
        thisy = v{k2};
        subplot(rows, rows, rows*(k1-1)+k2)
        if k1 == k2
            plot(thisx, thisy, 'b-', 'Linewidth', 2)
        else
            scatter(thisx, thisy, 'filled')
        end
        grid on;
        drawnow;
        % Turn off y axis except if it's the first column.
        if k2 > 1
            yticks([]);
        end
        % Turn off x axis except if it's the last row.
        if k1 < rows
            xticks([]);
        end
    end
end

Getting an error

Execution of script scatter as a function is not supported:

Error in scatter (line 68)

scatter(thisx, thisy, 'filled')

[Image Analyst]

Scatter is not a script. It's a built in function. You did not name your script "scatter.m" did you? You can't (or shouldn't) name your script after built-in functions like scatter or else you cannot run those built-in functions anymore.
