Version 3.0

Release date: 5 Septemer, 2016

This is a major new release of iNZight, so many things have changed. We hope you like them!

New Features

Here's just a few of the major new features to iNZight.

  • Example data sets available from the File menu
  • Play time can now be stopped, and the interval adjusted
  • Switch variables with the one below by clicking the "down" arrow to the right of the variable box
  • Maps Module - visualise geographical data:
    • Coordinates: if your data set includes GPS coordinates for each observation, iNZight will let you plot them on a map.
    • Countries: if observations have country names associated with them, you can colour countries on a map by another variable. Try this out with the Gapminder data set included in Example Data!
  • Dual Window mode - if you've used VIT, then this will be familiar to you. From File > Preferences, you can choose to have a separate window for graphs (as opposed to the built-in one).

Major Changes

We can't list everything here, but some of the important ones are listed below.

  • Plot toolbar has new icons
  • Add to Plot window completely redesigned to make plot modification easier
  • Resize points has been adjusted to resize the area proportional to the value. Also added an "emphasize" option, which scales sizes linearly.
  • COLOUR: new, better palettes have been introduced, including viridis, which are colourblind friendly.
  • Multiple Response has been overhauled to be more intuitive and fit in with the rest of iNZight.
  • (temporary) Just a quick workaround for analysing tables in iNZight: Dataset > Expand Table

Minor Changes

Given the magnitude of changes, there's little point mentioning the minor ones and bug fixes!

Patches

3.0.1 - 23/09/2016

  • Fix up labels and icons so plot toolbar and plot menu match
  • Fix a bug where two-level bar plots failed to draw
  • Fix a bug where empty levels in two-way bar plots failed to draw
  • Fix locator for dot plots
  • Fix the updates available checker

3.0.2 - 04/10/2016

  • Add "Updates Available" text back to the title (when they're available, of course!)

3.0.3 - 12/10/2016

  • Bug fix: can now change colours of histograms

Version 2.5

Release date: 08 November, 2015

New Features

  • specify colours for dotplots and scatterplots from the Add to Plot > Code more variables screen.

Patch 2.5.1 - 16/11/2015

  • correct the names and URLs in the 'Help > User Guides' menu
  • fix bug that occurs when 'Colour by' variable has only one unique value

Version 2.4

Release date: 12 October, 2015

New Features

  • Include FPC (finite population corrections) in survey designs

Major Changes

  • Replace the drag-drop boxes for variabes with drop-down boxes for an alternative method of variable selection. Drag-and-drop functionality has been retained.

Bug Fixes

  • Fix the enabling/disabling of buttons when survey designs are specified.
  • When closing the survey design window, they specified design is now checked for validity before saving the design.
  • Fix bug in the Multiple Response module that gave an "inverse" error message.
  • Various other small fixes throughout iNZight and other dependency pacakges. See their change logs for details.

Patch 2.4.1 - 21/10/2015

  • Remove dependency on RODBC package; this causes issues on Mac attempting to manually install.

PATCH 2.4.2 - 28/10/2015

  • Add option to display labels internally on numeric x factor
  • Fix from iNZightPlots for Get Summary (n.missing now correct)

Patch 2.4.3 - 02/11/2015

  • Improve smoothness of dotplot transitions by only redrawing when the scaling has changed.

Version 2.3

Release date: 4 August, 2015

New Features

  • SURVEY DESIGNS: iNZight can now handle survey designs (currently Strata, 2-stage (nesting) clustering, and a weighting variable. Plots take account of this structure and inference that displays (currently only trend lines on bivariate plots) use functions from the survey packages and thus incorporate weights.
  • Adjust the axis limits from the Add to Plot menu.
  • Adjust the number of bars displayed on a bar plot from the Add to Plot menu.

Minor Changes

  • the plot tool bar has been added to the Menubar at the top of the page. This allows users to work in a dual-window mode (with a narrow iNZight interface and a separate plotting window) and still be able to access plot functions.

Bug Fixes

  • fixes to a few issues occuring in dotplots
  • display an error if Add to Plot is called without any variables having been selected

Version 2.2

Release date: 16 June, 2015

New Features

  • users can specify a window size in File > Preferences
  • Links to the User Guides found on our website have been added, including help buttons in the Add To Plot and Inference Information windows.

Major Changes

  • LOCATE functionality now included for dot plots. Also fixes several bugs in the previous update for locating points in scatter plot.

Minor Changes

  • the "Row Operations" menu has been renamed "Data"

Patch 2.2.0-1 - 1/07/2015

  • iNZightPlots package: fix colour of segmented bar plots to match the legend

Patch 2.2.0-2 - 27/7/2015

  • Fix mapping of confidence intervals (instead of comparison intervals) to Year 12 intervals in dot plots.

Version 2.1

Release date: 25 May, 2015

New Features

  • New hexagonal binning plot available to large samples
  • Live updating sliders for the "Add to Plot" panel, which is now embedded into the main window rather than creating an additional pop-up window

Major Changes

  • The "Add to Plot", "Remove Additions" and "Inference Information" windows have been integrated into the main window with the aim of making the interface cleaner and easier to navigate.
  • When colouring points by a numeric variable, a continuous colour range is used rather than a discrete one.
  • The plotting package has been rewritten to accomodate survey designs (this will be integrated with iNZight itself at a later date). However, the plots have been modified to be cleaner and far more efficient. Additionally, the algorithms used for the inference information have been updated. For more information on this, see the iNZightPlots change log.
  • The "Get Summary" and "Get Inference" outputs have been redesigned to hopefully give a more intuitive, cleaner presentation of the information.
  • From dot plots and histograms, the comparison (and confidence) interval values can be read from the graph by clicking 'Get Values' in the 'Inference Information' panel. This includes the Year 12 intervals applied to medians.
  • LOCATOR: functionality for scatterplots vastly improved, allowing selection of related points, retaining points over multiple graphcs, and selecting points by a variable. (similar upgrades for dot plots coming in v2.2)

Minor Changes

  • the number of missing values is now displayed on the plot, broken down by variable
  • the list of options in the 'Add to Plot' window are now in a drop down menu, rather than radio buttons, to save space
  • many other small UI improvements

Bug Fixes

  • if colour by is set, but the graph is changed to a histogram, the legend is removed from the plot
  • fixes a bug in the plotting that was causing large values to fall off the axes of the plots
  • includes other patches from the previous version of iNZight

Patch 2.1.1 - 09/06/2015

  • fix a dependency issue required for aggregating data sets

Version 2.0.4

Release date: 18 November 2014

New Features

  • The data set name is displayed above the data view
  • The variable type is now displayed as a prefix to the variable names in the variable view
  • A new "Updates Available" shows up when new versions are released
  • A new Help tab that includes Licence information, and a link to the FAQ and Support pages

Minor Changes

  • In the "Remove Additions" window, "Remove segmentation" has been renamed to "Remove colour by" for bar plots, and "Restore default labels" is added to remove customised plot labels

Bug Fixes

  • Removes development text from Load Data window
  • Fixes a bug in the Locate Points feature when the scales are vastly different
  • Scroll bars added to Reorder Levels window
  • The menu has been moved above the plot tabs, so it no longer gets cut off

Patch 2.0.4-1 - 12/12/2014

  • fixed up the plot device in Time Series on Linux machines

Patch 2.0.4-3 - 10/02/2015

Version 2.0.3

Release date: 17 September, 2014

Major Changes

  • A new Multiple Response analysis module has been added to the Advanced menu. This utilises the iNZightMR package developed by Junjie Zeng

Minor Changes

  • "Add to Plot" window modified for barcharts - can show only CIs, and also selects comparison and confidence intervals by default

Bug Fixes

  • Includes a suite of bug fixes in the iNZightPlots package - see its NEWS file for these

Version 2.0.2

Release date: 17 June, 2014

New Features

  • can now cycle through all two-variable plots for a selected Variable 1
  • "play" button for the first subset by variable (automatically cycle levels)
  • data manipulation features added and modified

Minor Changes

  • can now specify to identify min/max points in a dot plot
  • in the Add to Plot window for barcharts, reworded "segment by" to "colour by" for consistency.
  • the transparency slider now runs from 0% to 100%

Bug Fixes

  • identify functionality works for subsets (except when multi plots at once)

Version 2.0.1

Release date: 27 March, 2014

New Features

  • Identify feature added to the "Add To Plot" menu. This allows users to interactively label points with id or any other variable. This feature works for both dot plots and scatter plots.

Minor Changes

  • Users can force scatter plots when the sample size is large, rather than using the alternative grid-density plot.

  • Missing observations can be converted to categorical levels. For categorical variables, the result is a new factor with the same levels as the original variable, but the additional missing factor level. For continuous variables, a new factor variable with two levels, missing and not missing is created.

Bug Fixes

  • Vertical sliders added to the Rename Levels and Rename factor levels windows.
  • Reorder levels now works as expected, including sort by frequency.
  • Bug where the iNZight window closes even if a user clicks cancel has been fixed.

Version 2.0

Release date: 18 January, 2014

Major Release

The entire iNZight module of iNZightVIT has been rewritten, with a multitude of changes along the way.
