Analytica Release Notes/Changes in Patch Build 4.4.2

<< What's new in Analytica 4.4

The patch build 4.4.2 fixes numerous bugs in Analytica 4.4.1. As a patch build, its focus is on bug fixes, not enhancements. This document lists bugs fixed since the 4.4.1 release.

If you are using Analytica 4.4.1, we recommend you upgrade by installing the most recent patch build. With 4.4.1 installed, your license will already be activated, it is just a matter of running the installer.

File Saving and Loading

  • When using Save As... or Save a Copy As..., a stray word Closing would often be written as the first word in the file. This causes a warning to appear when you reload the model, but otherwise doesn't interfere with the load. Fixed so that this stray word no longer is written during these save operations.
  • If you closed Analytica at a key point during program start up and initialization, it would cause an application crash.

Choice popups

  • The Choice popup menu now supports more than 254 items (now any number).
  • In long Choice popup menus, you can jump to an item by typing the first few characters of the item label.
  • The Font selection popup now displays the font names using their own font. If for some reason you need to disable this, in typescript type: Sys_ShowFontsOnPopups:0.
  • The font in a Choice button would shrink immediately following the selection from the popup.
  • When you are edit mode, the choice control in an input node now pops up when you click it. It is no longer necessary to switch to browse mode or hold the ALT key down.
  • Adjust to text didn't allow the choice control width to shrink, and in some cases didn't expand it enough.
  • When the options on a Choice menu are handles, the display of the labels now toggles between title and identifier when you toggle Show by Identifier (Ctrl+Y).
  • Choice popups now right-align numeric values.
  • Added a «separator» parameter to function Choice, which provides a capability for including separators within your own choice lists. Some single-letter options used to also display as separators, but these were odd and it also made it impossible to have a character choice popup without separators.
  • In one unusual situation, a choice input control displayed a SubTable button instead of a choice pulldown.

Influence Diagrams

  • When dragging a node from the toolbar to the diagram, the node size of the ghost image did not correctly reflect the default node size of the diagram. Now as you drag it, its size will change as you drag it over different diagrams to reflect the default size in that diagram.
  • The default node size, font face, and font size in one diagram was not being inherited from its parent diagram in the case where it had not been explicitly set in the child diagram.
  • With Resize Centered off and Snap to Grid on, resizing of a node would sometimes end up with a corner not on the grid.
  • Double clicking on checkboxes in input nodes would cause the object window to pop up.
  • When scrolling, the bottom border of nodes was sometimes not redrawn.
  • A situation in which a very old (3.1) legacy model encountered an error while loading caused it to use Clear Type fonts when it should have used legacy fonts.
  • When a definition was an empty list, [ ], with spaces between the brackets, the feature that allows you to draw an arrow from a variable to this list variable as a way of inserting the identifier in the definition didn't work.
  • In an esoteric case where a node color was determined via module inheritance, its color in the ghost image seen while dragging was incorrect.
  • After Copy Diagram, new nodes dropped outside the populated range of the diagram didn't display immediately.
  • In some cases when not using Clear Type fonts, the ghost image while dragging nodes was missing the titles.
  • Single-pixel white stripes would appear in some cases when moving a window across the diagram or when scrolling.

Tables

  • When an immense amount of text appears in a single cell (e.g., 125,000 caracters in one cell), a condition occurred in which Analytica became non-responsive for an extended period (e.g., 2 minutes) of time while trying to render the table, and would repeat the delay when even the slighted re-rendering was required.
  • When extremely long text appears in a single cell, with more than 32,000 pixels of height, its display would wrap around and overlap, making the other text in the cell unreadable. It now truncates appropriately at 32,000 pixels of height per cell.
  • There was a case in which the slicer position (which item is selected) was not correctly preserved and restored when a model was saved and restored.

Built-in functions

  • The SetIntersection function would hang in certain cases when the «resultIndex» parameter was used and matched the size of the result in length.
  • The descriptions for Function Radians and Funcion Degrees were swapped.
  • The description for the YearFrac function didn't mention and provide details for the «basis» parameter.
  • The description for the SpreadsheetCell function didn't include details on the «what» parameter.
  • When the "sum over an all-Null array" warning occurs and your pressed Edit Definition, it wasn't placing the caret on the offending call.
  • The Covariance and Correlation functions reported an internal error when a warning occurred during the evaluation of one of the array parameters.
  • The ArgMin and ArgMax functions returned an incorrect result when a warning occurred while evaluating its array parameter.
  • In one particular situation, the DetermTable function took an excessive amount of time to evaluate, which seemed to scale as O(n^2) rather than O(n).
  • The SpreadSheetRange function did not accept "BorderLeftStyle" as it should have.


Optimizer

Engine

  • When you changed the Use Excel Date Origin preference after result graphs were already computed, the result would adjust in an incorrect fashion, with the dates getting off.
  • Some new computed attributes have been exposed: Att_Dirty, Att_Obfuscated and Att_BrowseOnly. These apply to module nodes, and reveal whether the module has been dirty (has changes that need to be saved), or is obfuscated or browse-only. The Att_Dirty is read/write (so your button script can directly dirty or undirty modules). The other two are read-only.

Graphing

  • Equal-X histograms for PDF plots were not computing Equal-X histograms. They were actually computing Kernel Density Smoothed estimations using the small number of points usually used by a histogram. This would cause, among other things, negative values to show up in the PDF result where they didn't belong, etc. The Pdf function had the same problem.
  • When an Enhanced Windows Metafile image of a manually-scaled graph is copy/pasted into Word, and the graph has data that is way out of the manual scale range, the rectangule for the graph pasted into Word is too big.
  • When viewing a legacy (e.g., Ana 3.1 or earlier) model with a bar origin set, and then you add another comparison variable, the origin would end up listed twice.
  • A stacked bar graph did not display well in certain cases when Null values were present.
  • In some cases, the variable selected in the bar origin control did not match the bar origin actually used in the graph.
  • When the system variable Verbosity was set to 1 (not recommended), it was not possible to change the series color in a graph.
  • Some graphing options were lost after a variable was renamed, such as the bar origin that used that renamed variable, or axes ranges for the renamed variable.
  • The graph went blank (didn't redraw) when the slicer order was changed.
  • Some graphs didn't show initially when in maximized mode.
  • There was a case in which the comparision index selector pulldown was disabled initially in edit mode. (After a screen redraw it fixed itself).

Object Window

OLE Linking

Misc. User Interface

  • In the function finder's object listing window, many parameter names appeared twice, e.g., (type:type).
  • Added a keyboard short-cut, Shift+Ctrl+P, for Publish to Cloud...
  • Several items on various menus were missing the shortcut key. For example, when you press ALT+F and continue holding the ALT key down, you'll notice that one letter in most options is underlined. If you press that letter after ALT+F, it selects that option. Those that were missing a shortcut now have one.

Installer

Publish to Cloud

  • Subtle changes to make the Publish to Cloud... dialog more intuitive when you have multiple ACP accounts. You had to press OK at key times, with intuitive options disabled, and some information didn't display immediately.
  • When a model is too big for ACP (over 35MB), the error message that the model is too big took a very long time to appear when using Publish to Cloud...
  • The Manage Published Models... option is now enabled when no model is loaded.

Example Models and Libraries

  • The Dens_Poisson(0,0) function was returning NaN. The correct result is 1. This is fixed in the "Distribution Densities.ana" library.

Expression Assist

  • Even in 4.4.1, variables in the same module appear "above the line" in the identifier completion popup. However, variables with aliases or inputs/outputs in the module were not displayed, but should have been.

User Guide

  • Fixed some incorrect instructions on page 73 for aligning nodes.

ADE

  • The graph rendered by ADE when axis labels are handles always displayed the identifier. It should display the title when CARenderingStyle::HandleFormat is set to title.
