Is there a way to get shaded error regions on a scatter plot?

조회 수: 1(최근 30일)
Hi folks,
I have a scatter plot with known errors for each datapoint. Is there a way to create a shaded region around the scatter plot? Below is my graph, the red and cyan regions are the errors and the blue is the data. Is there a way to shade them and make them a continuous line, like the graph below?
I've attached the table below, along with my code.
hold on;
scatter(myData.Anisotropic_1, myData.AnisoMin);
scatter(myData.Anisotropic_1, myData.AnisoMax);
scatter(myData.Anisotropic_1, myData.("MPC aniso"), 'b');
title('Axiovision versus MPC, with reproducibility (r) in shaded region',"FontWeight","bold");
xlabel('Axiovision', "FontWeight","bold");
ylabel('MPC', "FontWeight","bold");
hold off;

@Image Analyst thanks, I've updated the post with my code and the relevant data!

It would help to have the data.
Try something like this —
x = linspace(0, 2*pi, 50);
y = sin(x) + 0.5;
err = rand(size(x))*0.5 + 0.5;
scatter(x, y, 'filled')
hold on
patch([x, flip(x)], [y-0.25 flip(y+err)], 'b', 'FaceAlpha',0.25, 'EdgeColor','r', 'LineStyle','-.', 'MarkerSize',20)
hold off
Experiment to get the desired result.

I’ve done that in the past, especailly when the outline to be filled would not yield to sorting and remained essentially impossible to define. Here, sorting worked.
