- Changed location of "ctrl+click to reset center" label.
- Changed ctrl+click to mean "reset zoom center and do not zoom nor place x_0".
version 1.2
- Changed "ctrl+click" to mean "reset zoom center".
version 1.1
- Graph basins button is now fixed (it was broken in the last update).
- Spacing of headers in iteration pane changed (broken in the last update).
version 1.0
- Version 1.0 designation.
- Menu bar added.
- Scientific notation altered: "E" becomes " E".
- Title of applet changed.
- ctrl+click=placement of cursor location in zoom panel.
- "Capture domain/range is changed to "Capture view."
version 0.83
- Utilized latest Default View menu.
version 0.82
- Default View drop-down menu has minimum width equal to size of unopened view.
version 0.81
- "Default Domain" has become "Default View".
- Default View drop-down menu automatically resizes when choosing domain/range that will not fit in default popup menu.
version 0.8
- Added ability of domain/range choice menu to capture current domain/range settings.
- Layout of domain/range choice menu has changed slightly.
version 0.7
- Allocation of memory to arrays dynamically has changed in order to fix bug.
- Domain choice menu bug has been fixed.
version 0.6
- I changed how I increment arrays so that User cannot cause out of bounds exception.
- Label widths have changed
- Made max iter label/field visible/invisible when clicking "Graph basins of attraction" box,
version 0.5
- Added pre-set functions via drop down menu.
>
- Changed color of iter point on axis.
- Fixed bug where basins of attraction did not move when axes location is reset.
- Size of applet has been reduced
- Number of iterations in iter pane are no longer constrained by max iterations used in Newton method.
Version 0.4
- Added ability to zoom via rectangle drag when function is not present.
- Fixed problem with switching between crossed and boxed axes.
- Use iterPane object to visualize iterations. This keeps header in place no matter how many iterations are visualized.
- Added "Update" button to update entry of initial value via keyboard.
- Changed "Focus Gained" property on y max field to be consistent with other domain/range fields.
- Fixed "Clear All" button so that it now properly clears and updates things.
Version 0.3
- Fixed bug that caused colors to change when zooming.
- Clear All button did not work properly. This has been fixed.
Version 0.2
- Global tab combined with local tab.
- Max iter field added
- Step tolerance field added
- Basins of attraction base convergence solely on step size.
- Ability to input initial val thru text box fixed
- Zooming bug fixed; basins of attraction now update properly
- Different background.
- Additioni of f(x_n) to sequence output.
Version 0.1
- Local tab allows user to iterate through Newton's method by clicking (or specifying) an initial value.
- Zoom in/out by scrolling mouse wheel or using slider on zoom panel.
- Zoom in/out by clicking Zoom on/off button and then right/left click on grapher
- Translate graph by dragging grapher.
- Iterate forwards and backwards through iterates with plus/minus button.
- Global tab allows user to see basins of attraction for given functoin. Number of roots found is displayed.
