gemseo.post.dataset.scatter module

Draw a scatter plot from a Dataset.

A Scatter plot represents a set of points \(\{x_i,y_i\}_{1\leq i \leq n}\) as markers on a classical plot where the color of points can be heterogeneous.

class Scatter(dataset, x, y, trend=Trend.NONE)

Bases: DatasetPlot

Plot curve y versus x.

Parameters:

• dataset (Dataset) -- The dataset containing the data to plot.

• x (VariableType) -- The name of the variable on the x-axis, with its optional component if not 0, e.g. ("foo", 3) for the fourth component of the variable "foo".

• y (VariableType) -- The name of the variable on the y-axis, with its optional component if not 0, e.g. ("bar", 3) for the fourth component of the variable "bar".

• trend (Trend | TrendFunctionCreator) --

  The trend function to be added on the scatter plots or a function creating a trend function from a set of xy-points.

  By default it is set to "none".

Raises:

ValueError -- If the dataset is empty.

class Trend(*values)

Bases: StrEnum

The type of trend.
