gemseo.post.dataset.curves module

Draw curves from a Dataset.

A Curves plot represents samples of a functional variable \(y(x)\) discretized over a 1D mesh. Both evaluations of \(y\) and mesh are stored in a Dataset, \(y\) as a parameter and the mesh as a misc.

class Curves(dataset, mesh, variable, samples=())

Bases: DatasetPlot

Plot curves y_i over the mesh x.

Parameters:

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

• mesh (str) -- The name of the dataset misc corresponding to the mesh.

• variable (str) -- The name of the variable for the x-axis.

• samples (Sequence[int]) --

  The indices of the samples to plot. If empty, plot all the samples.

  By default it is set to ().

Raises:

ValueError -- If the dataset is empty.
