Scatter plot in parfor loop

Hi everyone, I'm having some problems for creating a scatter plot. I'm using a parfor loop in order to address an optimization problem for sizing a transformer. In each iteration a suitable function is solved with the aim to find the geometrical parameters of the transformer. Hovewer two of the data that I have to evaluate at each iteration are the efficency and power density. After evaluating them thanks to the function I have written, I need to create an unique scatter plot 'efficiency' versus 'power density' that reports all the sizing that have been realized. Below I attached the matlab code I have implemented. Thanks for your supporting.

Variables r,i, frontal section and so on are free variables wich varing in a specific range of values

j=1;
parfor r= 1:3
    for i = [100 200 300]
        for frontal_section = 36
            for layer = 2
                for turn_per_layer = 5:10
                    for x = 0.22
                        for a = 0.66
                            for d_s_1 = 0.05
                                for d_s_2 = 0.05

Yes, but what is your question? What problem are you encountering?

[Stefano Menicanti]

If I run matlab code, scatter plot does not appear, I'm sorry if I have been unclear

Answer 1

[Matt J]

Parfor workers do not have display capability, but you can gather the data in the loop and plot it after the loop.

[Stefano Menicanti]

how can i do that?? thanks for your supoprting!

[Matt J]

Here is a simplified example:

parfor r=1:3 %generate data
    X{r}=rand(1,10);
    Y{r}=rand(1,10);
end

for r=1:3 %%plot data
figure;
scatter(X{r},Y{r})
end
