densityScatterChart

x=randn(1000,1);
y=randn(1000,1)
densityScatterChart(x,y);   % create a chart where color varies with density

%% You can set properties using name value pairs
% Create a chart where transparency varies with density:
densityScatterChart(x, y, 'UseColor', false, 'UseAlpha', true);

% Specify a title:
densityScatterChart(x, y, "Title", "My density scatter chart");

%% You can also set properties after making the chart:
d=densityScatterChart(x, y);

% Make a steeper density view
d.DensityExponent = 2;

% Use alpha, but make it a subtle effect by using a small range:
d.AlphaRange = [.2 .8];
