Added a colors package to script for creating vectors of colors for use with the Colors property of a series.
Added support for specifying a 4x4 transform for each <series> element using the child <transform> element or Transform property.
Note that auto-scaling does not account for the transform as auto-scaling is based on the series data itself. The transform allows the
series to be scaled, rotated, translated, etc. without modifying the series data. Transforms are best used with fixed axes ranges.
Added new methods to the matrixf package for creating various 4x4 transforms: translation, rotationAboutAxis, rotationFromQuaternion,
scaling and reflection. These transform matrices may be multiplied to combine transforms.

1.0.3 - December 22, 2015
Features
Repository
Added custom error pages.
Cross-Platform Apps
Added pan and zoom support to plots, as well as a manual attribute to enable or disable pan/zoom. Manual pan/zoom is enabled by default for
<plot>, <timePlot> and <xyPlot>, but disabled by default for <drawing>. Use <drawing> for 2-D animations because it also hides axis
labels by default. The <drawing> also uses lockAspectRatio on both axes by default to preserve aspect ratio.
Added an ignore attribute to <series>. If true then the series will be ignored by the auto-scaling algorithm, allowing scenes to be
constructed in the background of a <drawing> that do not affect auto-scaling. For example, combined with stripChart auto-scaling on both
axes, it is possible to get the effect of moving a vehicle around a large terrain by auto-scaling on the series for the vehicle but not the terrain
(so the plot looks like the view of a camera following the vehicle).
Changes
Repository
Added the ability for the author accounts to join groups.
Added email confirmation when registering through qdex Play.
Cross-Platform Apps
Removed the scaleAspectFit auto-scaling mode. Use lockAspectRatio on both axes to get the same behaviour as scaleAspectFit.

Added labels and titles to plot axes. Also added a title and subtitle to the plot.
Changes
Cross-Platform Apps
Added support for all the plot autoscaling modes on both axes. The shrinkOnly mode was removed.
The xmin, xmax, xauto, ymin, ymax and yauto attributes of <timePlot> and <xyPlot> are no longer supported. Use
child <axis> elements instead. Note that the <axis> elements now inherit their default options based on the parent plot so
only the attributes that are being changed need to be specified.

Added support for user accounts.
Added access control for documents; documents can be public, private or belong to a group.
Authors can create groups to limit access to their published documents to the users within that group.
Users can join groups and access documents within the group.
Cross-Platform Apps
Added a lockAspectRatio scaling option for <axis> elements. Only a one of the two <axis> within a <drawing> can be set to this mode. When used, the <axis> which is set to lockAspectRatio will maintain the aspect ratio while the other <axis> auto scales according to its own mode.
Added a scaleAspectFit scaling option for <axis> elements. To activate this mode, both of the <axis> elements within a <drawing> must be set to scaleAspectFit. When used, both axes will simultaneously resize (behaving like growAndShrink) while maintaining the aspect ratio.
Web-based images are downloaded and cached, and subsequent requests for the same image are loaded from the cache, if available. The cache is session-based and is cleared when the app is terminated.
If a file-based image referenced in a document can not be loaded, a standard image-not-available image is displayed instead. For a web-based image referenced in a document, a temporary placeholder image is displayed first, while the image is being fetched. If the web-based image is successfully fetched or loaded from the cache it replaces the placeholder image. Otherwise, the placeholder image is replaced by the image-not-available image.
Changes
Cross-Platform Apps
<xyPlot> defaults now use scaleAspectFit for its X and Y axes.

Added a <signalGenerator> element for simulation that can produce a sine, square, triangle, sawtooth or random waveform. The waveform may be changed in script.
Display cover image, title and author from the document metadata in the library.
Added a draw attribute to <series> that allows series to be drawn with different drawing modes, such as points, lineSegments, line, closedLine, triangles, segmentedFill and radialFill. The triangles, segmentedFill and radialFill options allow filled shapes to be created efficiently. The lineSegments option allows many line segments to be drawn efficiently. The line mode is the default mode, which is used for drawing a continuous line from the points in the series. This is an advanced feature that is intended to make optimal use of native GPU rendering.

Fixed a bug where multiple plots would fail to render consistently on Android.
Fixed a bug where having plots on 3 or more pages would cause the app to crash.
Fixed a bug where loading documents on 64-bit Android hardware would crash.
Fixed text alignment not working for paragraphs and equations.
0.5.0 (8) - June 19, 2015
Features & Enhancements
XML Authoring
<series> in a <plot> elements can now have custom thickness and colors.
Added support for <figure> elements.
Changes
Cross-Platform Apps
Simplified error messages for .NET runtime errors (such as invalid axis ranges set from script).
XML Authoring
Changed reference resolution sequence to allow document elements to be initialized from <script>.
Moved <title> element from a child of <document> to a child of <metadata>.
The <metadata> element is now required, as well as its <title>, <creator> and <abstract>
child elements. The text of the abstract must be 100 to 500 characters in length.
Updated the schema.
Bugfixes
Cross-Platform Apps
Fixed an issue where plot lines were thicker on low resolution displays.
Added a check to ensure that <axis> min and max values are valid.
Fixed an issue where the axes of a plot were not being reset properly.
Added an error when a document is empty and has no pages.
Fixed an issue when <data> elements are provided with values and an entry is missing.
iOS App
Fixed an issue where plots did not render after the application was paused.
0.5.0 (7) - June 17, 2015
Features & Enhancements
Cross-Platform Apps
Added support for axis scaling modes in plots. Plots defined within a <xyPlot> or <timePlot> tag will
now work properly.
Added support for the <link> text formatting tag to add hyperlinks to the text within paragraphs, e.g., <link url="http://www.mywebsite.com">My Website</link>
Changes
XML Authoring
Custom <drawing> elements can now define their own <axis scaling="{mode}" .. />.
Supported modes for the X-Axis are None, Fixed, GrowOnly, GrowAndShrink, Scope and StripChart.
Supported modes for the Y-Axis are None, Fixed, GrowOnly and GrowAndShrink.
Removed the parent attribute for <style> and replaced it with link. The link attribute may take
a list of style names, separated by spaces.
Removed the cascading attribute for <style>. Only individual styles, such as <bold> now have the
cascading attribute, which defaults to false.
Added a <signal> element for simulation that allows an element within the document to act as a signal
in a simulation. For example, buttons, sliders and text input fields can act as signal sources.
The plot scaling mode Sweep has been renamed to Scope.
Lua Scripting
The <timePlot> and <xyPlot> elements now have XAxis, YAxis and Plot properties for accessing
the axes and plot respectively. The elements themselves are actually drawings containing predefined axes
and a plot and are provided for convenience.
Bugfixes
Cross-Platform Apps
Styles defined in theme files should now behave as expected when predefined styles in the default theme
are already defined. The styles in the theme files will extend style sets of the same name in the default
theme.
0.5.0 (6) - June 14, 2015
Features & Enhancements
Cross-Platform Apps
Added analytics tracking to gather diagnostic information (e.g. crashes) during the beta.
Changes
XML Authoring
Changed the <switch> element so that its Selection property is a vector, not a scalar. Also added a
select attribute for setting the initial Selection property value. This change allows the <switch> to
route multiple signals to the output, or even multiple input ports to multiple output ports.
Added notify(message) function to script to allow non-intrusive notification messages to be presented to
the user e.g. notify("Hi there!");.
Bugfixes
Cross-Platform Apps
Fixed an issue where grid lines did not appear in plots on hardware.
Fixed an issue where animated line drawings would flicker while being drawn.
Android App
Fixed an issue where depth rendering was incorrect for plots.
0.5.0 (5) - June 9, 2015
Features & Enhancements
XML Authoring
Added <onStateChanged> callback to simulations. The QModelSimulation now
has public constants for the states for use with script e.g. if (state == mysim.Running).
Added <timeplot> and <xyplot> elements for simplified plotting. If no data series is provided it creates a
default data series so plots are very easy to create.
Added boolean "time" attribute to <probe> to allow the probe to be used for X-Y plotting. If time = false then
it treates the input vector as consisting of (x,y) pairs.
Added a <switch> system for simulation.
Cross-Platform Apps
Added toast notifications in the library to indicate when the library has
refreshed and when a document has been successfully downloaded.
Changes
XML Authoring
The <probe> element now clears its target (e.g. data series) on simulation start or reset automatically,
obviating the need to call Clear in script.
Bugfixes
Android App
Fixed an issue with math not being displayed at the end of a line of text.
Pressing the back button from the library closes the app instead of showing a blank white screen.
XML Authoring
Fixed <transferFunction> not being recognized as a valid element.
0.5.0 (4) - June 8, 2015
Features & Enhancements
Cross-Platform Apps
Supports older hardware running OpenGL ES 2.0.
Bugfixes
Android App
Fixed an issue with multiple plots rendering inconsistently.
