reports Package#

What is the reports package?#

The report package offers versatile and powerful tools for generating detailed and insightful reports for both standard simulations and design of experiments (DOE) analyses.

Two main classes are available within the package: Report and ReportDOE, each tailored for specific use cases within the domain of simulation analysis and reporting.

The Report class provides a convenient way of post-processing simulation results and is intended for regular simulations. It handles the generation and presentation of reports based on simulation data. Taking advantage of Jupyter Notebook and the numerous plotting libraries of python, the results of one or multiple MotionSolve runs can be formatted and visualized in an automatically generated Jupyter Notebook.

The generated report contains pages, plots and curves, which are configured according to your preferred template. The template can be a pltpy configuration file, or you can interactively build a custom template using the functionalities illustrated in the following section.

You can choose the plotting library that fits your work best and your results will be visualized accordingly. Due to the dynamic nature of Jupyter Notebooks, further customization of the report is feasible. We encourage you to modify the code in order to adjust the report to your preferences.

The functionality of this package is not restricted to the Jupyter Notebook only. You can use it to create standalone plots interactively while coding in msolve. To utilize the package in this manner, the only thing you have to do is not specify the Report.output attribute.

The ReportDOE is tailored for DOE analyses. It extends the reporting capabilities to suit the specific requirements of DOE methodologies, including handling complex data structures and providing specialized visualizations and statistical tools such as ANOVA table and Pareto Chart. It is an ideal solution for extracting and presenting insights from DOE data, making it a valuable asset for researchers and analysts in various fields. In addition, it makes available the entire experiment data structure so that you can use, manipulate it and perform post-processing operations.

Together, these classes within the report subpackage form a cohesive and dynamic toolkit, allowing users to transform complex simulation data and DOE analyses into accessible, insightful, and visually engaging reports.

Classes#

class Report(**kwds)#

Creates a Jupyter Notebook and populates it with model information and visualized simulation results.

The generated simulation report is a collection of pages, which are collections of plots. Plots contain one or multiple curves. The Report class is an easy and flexible tool to post-process a simulation or a series of simulations.

Parameters

  • run (SimulationResults/SimulationResultsHistory/path object, optional) – The simulation results. This can be either an instance of a msolve SimulationResults or SimulationResultsHistory instance or a path to a pickle file containing a serialized SimulationResults or SimulationResultsHistory object.

  • plt_py (path object, optional) – A plot config file in the style of Inspire Motion. The file defines a report template that contains pages, plots, and curves.

  • output (str, optional) – The output file name (.ipynb). If not specified, standalone plots will be interactively created instead.

  • plotting_package (str, default='matplotlib') – The name of the plotting package that is to be used. Choose between ‘matplotlib’, ‘bokeh’, ‘plotly’.

  • image (path object, optional) – Path to an image file that is to be used in the Jupyter Notebook report.

  • subtitle (str, optional) – A title for the analysis that is to be post-processed in the report.

Raises

ValueError – If the provided ‘run’ object is not a valid SimulationResults (or SimulationResultsHistory) instance or pickle file, or if an error occurs during setup.

__call__()#

Allows an instance of the class to be callable. It generates a report tailored to the specified attributes.

page(*args, **kwargs)#

Creates a Page instance and adds it to the Report.

Parameters

Parameters

**kwargs – See Plot for valid keyword arguments.

Returns

The Plot instance.

class ReportDOE(**kwds)#

Class for reporting Design of Experiments (DOE).

This class handles the generation of reports for DOE. It can take either an instance of DesignExperiment or a path to a CSV file containing experiment data. It utilizes a plotting package (default ‘matplotlib’) for generating visual representations of the experiments.

design_experiment#

An instance of DesignExperiment.

Type

DesignExperiment

serialized_design_experiment#

Serialized version of the design_experiment. Can be used to perform additional post-processing, visualization and manipulation of the design space in the report.

Name of the plotting package to be used for generating plots.

Type

str

csv_file#

Path to the CSV file containing the experiment data.

Type

str

Raises

  • ValueError – If both or neither design_experiment and csv_file are provided.

  • ValueError – If the provided design_experiment is not an instance of DesignExperiment or if the csv_file is not a string.

Parameters

  • design_experiment (DesignExperiment, optional) – An instance of DesignExperiment.

  • csv_file (str, optional) – Path to a CSV file containing experiment data.

  • output (str, optional) – Output destination for the plots. If None, plots will be pop-ups.

  • plotting_package (str, optional) – The plotting package to use. Defaults to ‘matplotlib’.

__call__()#

Allows an instance of the class to be callable. It generates the notebook.

addSummaryTable()#
class Page(**kwds)#

Creates a Page instance that will be part of a Report.

Parameters

  • name (str, optional) – A name for the page.

  • layout (str, default='1x1') – The layout of the page. Valid options are ‘1’, ‘1x1’, ‘1x2’, ‘2x1’, ‘2x2’.

Warning

The Page class should not be instantiated by the user. Use Report.page instead.

class Plot(**kwds)#

Creates a Plot instance that will be part of a Page.

Parameters

  • report (Report) – The Report instance that the plot will be in.

  • page (Page) – The Page instance that the plot will be in.

  • legend (str, optional) – The plot legend.

  • grid (bool, default=True) – Dictates if the plot will have grid.

  • xaxis (str, optional) – The x-axis label.

  • yaxis (str, optional) – The y-axis label.

  • name (str, optional) – A name for the plot.

  • curves (list [Curve], optional) – A list of the Curve instances that will be plotted.

Warning

The Plot class should not be instantiated by the user. Use Report.plot instead.

addCurve(*args, **kwargs)#

Adds a curve to the plot.

Parameters

**kwargs – Pass in a curve instance using the keyword ‘curve’, or pass in keyword arguments of the Curve class to automatically create a Curve instance.

class Curve(**kwds)

Usage Information#

There are numerous ways you can use the reports package, depending on the Report attributes that you will specify. A brief summary is given below:

  • Depending on the run data

    1. You can pass in a SimulationResults/SimulationResultsHistory object,

    2. You can pass in a pickle file containing serialized run data.

  • Depending on the template

    1. You can pass in a pltpy config file,

    2. You can create your own template interactively.

  • Depending on the output name

    1. Generate a Jupyter notebook by specifying an output name,

    2. Create plots interactively by neglecting the output name.

Examples

In the first example, we illustrate how to generate a report, using run data in the form of a SimulationResults object. The format of the report is interactively built. This example uses the Report class. An example for the ReportDOE class can be found in DOE analysis documentation.
