Scatterplots

### 18.2.2 Scatterplots

A scatter plot is simply a set of points plotted on axes. The scatterplot or nuage_points command draws scatter plots.

- scatterplot takes two arguments: xcoords and ycoords, a list of x-coordinates and y-coordinates. You can also combine them into a matrix with two columns (each list becomes a column of the matrix).
- scatterplot(xcoords,ycoords) draws the points with the given coordinates.

#### Example

scatterplot([[0,0],[1,1],[2,4],[3,9],[4,16]],display=point_width_3+point_point+red)

or:

scatterplot([0,1,2,3,4],[0,1,4,9,16],display=point_width_3+point_point+red)

The batons command will also draw a collection of points, but each point will be connected to the x-axis with a vertical line segment.

- batons takes two arguments: xcoords and ycoords, a list of x-coordinates and y-coordinates. You can also combine them into a matrix with two columns (each list becomes a column of the matrix).
- batons(xcoords,ycoords) draws the points with the given coordinates and connects them to the x-axis with vertical line segments.

#### Example

batons([[0,0],[1,1],[2,4],[3,9],[4,16]])
