Any idea to make scatter plot more clear to read?

there are multiple points that are hidden under the red and orange points. Any idea to make this plot more understandable?

Have you checked out the properties for scatter plots?
Consider changing your marker style or marker size. You can also adjust you axis limits to effectively zoom in on the data, potentially helping spread the data out.

@cris:
I dont think changing the marker style will solve the issue because they will again hide behind the red/orange points.

Hi Zeynab-san,
>My data is 2D why scatter3?
OK. The following is what I thought:
% Sample data
rng('default');
D1 = [abs(randn(20,1)),rand(20,1)];
D2 = [abs(randn(20,1)),rand(20,1)];
D3 = [abs(randn(20,1)),rand(20,1)];
% Visualize using 2D scatter
figure
hold on
scatter(D1(:,1),D1(:,2),'filled')
scatter(D2(:,1),D2(:,2),'filled')
scatter(D3(:,1),D3(:,2),'filled')
legend({'Data1','Data2','Data3'},'FontSize',12)
grid on
box on
% Visualize using 3D scatter
figure
hold on
scatter3(ones(20,1),D1(:,1),D1(:,2),'filled')
scatter3(ones(20,1)*2,D2(:,1),D2(:,2),'filled')
scatter3(ones(20,1)*3,D3(:,1),D3(:,2),'filled')
ax = gca;
ax.XTick = 1:3;
ax.XTickLabel = {'Data1','Data2','Data3'};
view([60 45])
grid on
box on
