GraphingLib 1.5.0 Release Notes#

Highlights#

  • New Polygon object to create any given shapes from vertices and supporting set operation methods

  • New FitFromFOTF object to fit using a first order transfer function

  • You can now set a custom style as default to replace plain

  • Many new features for Curve, Scatter and Point objects

New Features#

New function get_styles#

The new function get_styles makes it possible to fetch all available styles.

(pr-420)

Added possibility to plot the area between 2 curves#

The method get_area_between from the Curve class has a new parameter other_curve making it possible to get the area between two Curve objects.

(pr-422)

Added add_error_curves method#

Added add_error_curves method to the Curve class to display error around a curve with curves instead of error bars.

(pr-426)

New aspect_ratio parameter for Figure#

The parameter aspect_ratio is used to specify an aspect ratio for the axis scaling. Can take a float, “auto” or “equal”.

(pr-428)

Added absolute value functionality to Curve and Scatter#

It is possible to get the absolute value of a Curve or Scatter by passing a Curve or Scatter object to abs().

(pr-432)

Added object copying methods#

All Plottables now have a copy method to create a duplicate of the object.

(pr-441)

Added in-place operators for Curve and Scatter#

Implemented in-place operators (+=, -=, *=, /= and **=) for Curve and Scatter objects.

(pr-442)

Added FitFromFOTF (first order transfer function)#

New FitFromFOTF object to create fits using a first order transfer function.

(pr-443)

New Curve and Scatter slicing methods#

Curve and Scatter now have create_slice_x and create_slice_y methods to create a new object from a slice of an existing object.

(pr-448)

New Polygon object#

A new Polygon object to plot a general polygon from a list of vertices.

(pr-450)

Added possibility to set different default style#

Added two new functions, set_default_style to set your default style and get_default_style to get the name of the current default style.

(pr-453)

Getters and setters for every objects’ properties#

All properties can now be set and retrieved using object.property notation.

(pr-464)

Manual legend placement and columns#

Placement of the legend can now be controlled manually in Figures when using show and save. A number of columns can also be specified.

(pr-481)

Added support for color maps with Scatter#

Scatter has new parameters color_map and show_color_bar to specify a color map and display the color bar. To be used in combination with face_color to provide intensity values.

(pr-503)

Added support for color cycles and colormaps with Scatter edge_color#

The edge_color attribute of Scatter objects now accepts a list of colors or intensities. When set to “color cycle” or if this is what the style’s default is set to, the edge_color will cycle through the colors in the style’s color cycle.

(pr-537)

DPI resolution now supported#

DPI resolution is now available as a style controlled parameter and can be overridden in the Figure and MultiFigure save methods.

(pr-559)

More flexibility for Point colors#

Point face and edge colors can now be set to a color or None (transparent). Text color can also be set to a color or to “same as point” (the default) to match the point color, with the edge color being prioritized over the face color if both aren’t None.

(pr-561)

Other Changes#

Use trapezoidal integration for create_integral_curve#

Changed the method used for numerical integration of curves to work with uneavenly spaced data and added a parameter initial_value.

(pr-433)

Simplified VectorField options#

Options for VectorField arrows have been simplified and the arrows shape is now controlled only by arrow_width and arrow_head_size.

(pr-476)
