algviz 0.3.0

• Support to layout different display objects and assemble the animation sequences. To use this feature, you need to do these things:

  1. The layout engine is platform specific, please make sure your OS is Windows or Linux and your platform is amd64/x86_64 architecture.

  #. Add the layout=True parameter when creating the ``Visualizer` <https://algviz.readthedocs.io/en/0.3.0/api.html#algviz.visual.Visualizer>`_ object (the default value of layout is False for compatibility). #.

  Add the ``Visualizer.layout` <https://algviz.readthedocs.io/en/0.3.0/api.html#algviz.visual.Visualizer.layout>`_ function in your code where you want to assemble the animation sequences (usually at the end of the code path).

  

• Fix bug: Histogram vector zero height cell text size error.

algviz 0.2.3

• Adaptation to recent versions of the ipython library (8.0.0 ~ 8.12.0).

• New feature: Added the ``generateRandomGraph` <https://algviz.readthedocs.io/en/0.2.3/api.html#algviz.graph.generateRandomGraph>`_ interface, related issue7.

• Fix bug: Access table with cursor throw exception when “show_index=False”

algviz 0.2.2

• Add a new class Map which can be used like the Python dict builtin.

  

• Fix bugs: table.reshape error, algviz.parseBinaryTree issue.

algviz 0.2.1

• Layout and display optimizations for RecursiveTree and undirected graph.

• Fix some typos and small mistakes.

algviz 0.2.0

• New feature: add animation effect for text labels in Vector, Table and Graph nodes.

  

• New interfaces: Vector.removeMarks, Table.removeMarks, SvgGraph.removeMarks can remove multiple color marks in the display object.

• Change interface: Table.mark adds two parameters r2 and c2 to support marking multiple elements in the given rectangle area.

• Fixed bugs:

  • Unit tests failed for Logger.

  • Display area is clipped in some Logger object.

  • Refresh error when calling Logger.clear.

algviz 0.1.8

• New interfaces:

  • TreeNode.childCount returns the children nodes count.

  • GraphNode.neighborCount returns the neighbors count of this node.

• Logger new display style: set the log font size and wheather to show log line num in the Visualizer.createLogger interface.

algviz 0.1.7

• New interfaces TreeNode.childAt, TreeNode.childIndex and TreeNode.removeAt for TreeNode.

• New interfaces GraphNode.neighborAt, GraphNode.neighborIndex and GraphNode.removeAt for GraphNode.

algviz 0.1.6

• Interfaces change

  • Visualizer.createCursor swap the position of parameters offset and name.

  • Visualizer.cursorRange swap the position of parameters step and name.

  • Add a new class RecursiveTree, which can make it easier to track the recursive algorithm.

• Fixed bugs:

  • Crash when the TreeNode value is an empty string.

  • CursorRange iterator range error.

algviz 0.1.5

• Fixed some known bugs about cursor.

• Update some constructor interfaces.

algviz 0.1.4

This version adjusts the interfaces to create or remove cursors. Instead of creating the identical cursors bound with different Vector or Table objects, you can create the cursor one time then it will be bound with display objects which been accessed by the cursor.

• Interfaces change:

  • `Cursor <https://algviz.readthedocs.io/en/0.1.4/api.html#algviz.cursor.Cursor>`_ operations extend:

    • Add assignment operation: <<

    • Add mathmatics operations: %, +=, -=, *=, //=, %=

  • Added interfaces: Visualizer.createCursor, Visualizer.removeCursor, Visualizer.cursorRange

  • Deprecated interfaces: Vector.new_cursor, Vector.remove_cursor, Table.new_col_cursor, Table.new_row_cursor, Table.remove_cursor, Cursor.dec, Cursor.inc, Cursor.update.

• Added new class: AlgvizTypeError.

• Fixed bugs:

  • Can not access Table row/column index with Cursor object.

  • Cursor move distance error when cell width is not equal with cell height in Table/Vector.

algviz 0.1.3

• Interfaces change:

  • Remove colorsInfo() and colors, use color_black, color_red and so on instead.

  • Update interface Visualizer.createTable: change the type of paramter cell_size from float into tuple(float, float), in order to support setting the cell height of table elements.

  • Update interface Visualizer.createVector:

    • Change the type of paramter cell_size from float into tuple(float, float), in order to support setting the cell height of vector elements.

    • Change the paramter bar into histogram(type is bool, means display the data in the form of a histogram).

  • Update interfaces Vector.mark, Table.mark, SvgGraph.markNode and SvgGraph.markEdge: change the default value of paramter hold from True into False.

• Display change:

  • Change Logger display format into normal string.

  • Display the name of visualizer objects by string instead of Table.

  • No longer mark items cell automatically when access or modify data in items.

• Remove useless comments and titles in the SVG output result of SvgGraph..

algviz 0.1.2

• SVG animation visual effection optimization: divide the animation of disappearing, moving and appearing into different animation sequences.

• Add new exceptions: AlgvizParamError, AlgvizRuntimeError, AlgvizFatalError.

algviz 0.1.1

• Add cursor support for Vector and Table.

  

  • Add Cursor class to display the cursor position change in Vector and Table.

  • Add interface new_cursor, remove_cursor in Vector.

  • Add interface new_row_cursor, new_col_cursor in Table.

• Add reshape interface in Table.

• Compress SVG size for tables with very many cells.

• Changed the index range check rule for insert, pop, swap interfaces in Vector, raise exception when index out of range.

algviz 0.1.0

This is the first public release of algviz. Support animation generation for vector, table, linked list, tree and graph data structures in jupyter notebook.
