scatter

Scatter plot

Usages

scatter(x, y)

• Generate a scatter plot with $x$ and $y$ data.
• x and y are vectors that contain the $(x,y)$-coordinates of the data points.
• If x or y is complex, only the real parts will be used.
• It uses the default point size and marker edge color.
• By default, a scatter plot has invisible lines and transparent marker face color.

scatter(x, y, c1, ..., cM)

• c1, ..., cM should be either one of the following:

  1. (Marker size) A real positive scalar that specifies the size of all markers in the plot.
  2. (Marker edge color) A vector of 3 real numbers lying in $[0,1]$, which specifies the RGB values of the marker edge color of all markers in the plot.
  3. (Filled or not) A character vector specifying the line specifications. It should be either 'filled' or a valid line specification string. When it is equal to 'filled', the marker will be filled using the marker edge color.

• Note that cj can overwrite ci if j > i. For example, in scatter(x, y, s, [1, 0, 0], 'g'), 'g' overwrites the color setting [1, 0, 0].

scatter(x, y, c1, ..., cM, Name1, Value1, ..., NameN, ValueN)

• This is the same as scatter(x, y, c1, ..., cM) with additional input arguments that specify the values of various attributes.
• Attribute names are given by Name1, ..., NameN and their associated values are specified by Value1, ..., ValueN, respectively.

Examples

• Scatter plot of randomly generated x- and y-data in blue color and 6.0 point size

Input

x = randn(1,100);
y = randn(1,100);

% Marker size of 6.0 and RGB values of 0,0,1.
scatter(x,y,6.0,[0 0 1])
