Sympy Plot Backends v3.3.0

What's Changed

• Control system plotting

  • Fixed bug with missing title of plot_root_locus.
  • Implemented sgrid based on Matplotlib projection.
  • Improved sgrid support on Bokeh interactive plots.
  • Improved labeling of MIMO systems.
  • step_response, impulse_response, ramp_response are now able to compute an appropriate upper time limit for the simulation.
  • Updated code to use control 0.10.0. As a consequence, Python 3.9 is no longer supported by this module.

• Improvements of interactive plots:

  • Added support for multiple-values widgets, like RangeSlider.

  • Improvements of spb.interactive.panel:

    • Simplified underlying architecture. Previously, InteractivePlot inherited from param.Parameterized: widgets were class attributes. Instantiating a new interactive plot would make the previous instance completely unusable. This inheritance has been removed. Now, widgets are instance attributes. Multiple instances work perfectly fine.
    • Added support for widgets of Holoviz Panel.
    • Updated plotgrid to work with the new architecture.

  • Improvements to documentation.

• Fixed bug with legend of plot_vector.
