zvsxy module

Draw a variable versus two others from a Dataset.

A ZvsXY plot represents the variable \(z\) with respect to \(x\) and \(y\) as a surface plot, based on a set of points :points \(\{x_i,y_i,z_i\}_{1\leq i \leq n}\). This interpolation is relies on the Delaunay triangulation of \(\{x_i,y_i\}_{1\leq i \leq n}\)

class gemseo.post.dataset.zvsxy.ZvsXY(dataset, x, y, z, x_comp=0, y_comp=0, z_comp=0, add_points=False, fill=True, levels=None, other_datasets=None)

Bases: DatasetPlot

Plot surface z versus x,y.

Parameters:

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

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

• y (str) – The name of the variable on the y-axis.

• z (str) – The name of the variable on the z-axis.

• x_comp (int) –

  The component of x.

  By default it is set to 0.

• y_comp (int) –

  The component of y.

  By default it is set to 0.

• z_comp (int) –

  The component of z.

  By default it is set to 0.

• add_points (bool) –

  Whether to display the entries of the dataset as points above the surface.

  By default it is set to False.

• fill (bool) –

  Whether to generate a filled contour plot.

  By default it is set to True.

• levels (int | Sequence[int]) – Either the number of contour lines or the values of the contour lines in increasing order. If None, select them automatically.

• other_datasets (Iterable[Dataset]) – Additional datasets to be plotted as points above the surface.

Raises:

ValueError – If the dataset is empty.

execute(save=True, show=False, file_path=None, directory_path=None, file_name=None, file_format=None, properties=None, fig=None, axes=None, **plot_options)

Execute the post processing.

Parameters:

• save (bool) –

  If True, save the plot.

  By default it is set to True.

• show (bool) –

  If True, display the plot.

  By default it is set to False.

• file_path (str | Path | None) – The path of the file to save the figures. If None, create a file path from directory_path, file_name and file_format.

• directory_path (str | Path | None) – The path of the directory to save the figures. If None, use the current working directory.

• file_name (str | None) – The name of the file to save the figures. If None, use a default one generated by the post-processing.

• file_format (str | None) – A file format, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.

• properties (Mapping[str, DatasetPlotPropertyType] | None) – The general properties of a DatasetPlot.

• fig (None | Figure) – The figure to plot the data. If None, create a new one.

• axes (None | Axes) – The axes to plot the data. If None, create new ones.

• **plot_options – The options of the current class inheriting from DatasetPlot.

Returns:

The figures.

Raises:

AttributeError – When the name of a property is not the name of an attribute.
