Use the '''Themes Library''' to quickly update your diagram and graph styles with some new and updated preset themes! Simply add the '''Themes Library''' into your model to update your model’s theme. Here is a video to walk you through the process:

When you open the '''Themes Library''', you’ll see the following screen:

[[File:Colorthemeslibrary.jpg|alt=|frameless|600x600px]]

The '''Themes Library''' shows examples of each node class, including text, picture, form, and slider defaults as well as an Example Diagram to show how the selected theme looks. To the right of the example nodes there is a button '''Apply example node styles as default style'''. Under these examples there is a '''Select Diagram Theme''' menu which allows you to select theme and other options, and to the right of that menu there is an '''Additional Settings''' module and two buttons, '''Set all nodes to default color and border styles''' and '''Export Anastyle'''. At the bottom of the window is the '''Graph Examples''' menu which allows you to select graph themes and see examples of the selected settings on various graph types. 

== Download ==
You can download the Themes Library here: [[Media:Themes Library.ana|Themes Library.ana]]. To use it, simply add the library into your model.

Note that as of Analytica 6.5, the Themes library is included in Analytica.  If you go to File > Add library from Analytica, scroll down to see the Themes library.

== Notes ==

* Nodes and graphs that already have non-default options selected will not update when defaults are changed. If you have nodes with explicit color and style settings that you would like to revert to model defaults, use the '''Set all nodes to default color and border styles''' button at the bottom right of the library.
* Arrow border colors will only change in Analytica versions 6.3.0 or newer
* [[Slider|Slider bars]] (and styles) will only display in Analytica versions 6.3.0 or newer
* Bar graph outlines will only change in Analytica versions 5.0.7 or newer

== Make a new style ==

[[File:Colorthemeslibrary examplenodes.png|892x892px]]

In Edit Mode you can change the colors and other styles of these example nodes at the top of the library diagram. Use the [[Color palette]] and [[Node Style dialog]]. Once you've set the styles you want, click the '''Apply example node styles as default style''' button to set these styles as the model default style. They will apply to all nodes in the model (except any that have their own nondefault styles). You can then export these styles as an Anastyle using the '''Export Anastyle''' button at the bottom of the library window, so you can easily apply them to other models. 

Note that the font styles of these nodes will '''not''' be applied to the default style. The default model font is set in the [[Diagram Style dialog]].

Any changes made to these nodes and the default style will be reset if you select different Diagram colors in the '''Select Diagram Theme''' menu below.

== Select Diagram Theme Menu ==
[[File:Selectdiagramtheme.png|alt=|frameless]]

Use the '''Select Diagram Theme''' menu to update your model’s default theme options. This menu includes the following options:

* Diagram colors
* Node borders
* Font size
* Font

==== Diagram colors ====
The '''Diagram colors''' drop-down select menu allows you to select one of our preset themes. Changing this menu automatically updates model defaults to the selected theme. 

The available themes are shown in the table below:
{| class="wikitable"
|+Diagram Color Themes available in Themes Library

|}
See the [https://lumina.com/behind-the-scenes-5-3-color-themes/ Lumina Blog] for insight on how the Viridis and Plasma themes were designed.

==== Node borders ====
Use the '''Node borders''' option to select node border style.  

Select ''None'' to turn off node borders. Selecting this option will also toggle borders on and off in graphs. ''Monochrome'' sets a single border color for all nodes and ''Color'' sets custom border colors depending on each nodes’ color. See the table below for examples of the options:
{| class="wikitable"
|+Examples of nodes with different Node borders options

!Color
|-
|[[File:Examplediagramnoborders.png|frameless]]
|[[File:Examplediagramwithstandardborders.png|frameless]]
|[[File:Examplediagramwithnodecolorborders.png|frameless]]
|}
Some themes will automatically update the Include borders option to the selected theme’s  default when you change themes, but this option can still be changed according to your tastes. 

==== Font Size ====
The '''Font size''' menu allows you to change the font size of your model. This will affect the text and tables in diagrams, graphs, Object View, and Result View.

==== Font  ====
The '''Font''' menu allows you to change the font of your model. This will affect the text in diagrams and graphs.

== Graph Examples Menu ==
[[File:Graphexamplesmenu.png|frameless|512x512px]]

The '''Graph Examples''' menu allows you to change your graph theme and view various example graphs. By default, the S'''ame diagram and graph themes''' option is selected and graphs will match the selected '''Diagram colors'''. 

If you uncheck the '''Same diagram and graph themes''' option, several menus will appear in the top section of the menu. These include the following options: 

* '''Graph theme''' provides a list of pre-made graph themes for you to choose from. Note that if you change the graph theme, the other options will update to the theme defaults. 
* '''Graph font''' changes the font used in graph labels and titles. 
* '''Line thickness''' changes the thickness of the line in line graphs. 
* '''Include graph borders''' toggles borders on and off in graphs. 
* '''Adapt font size to window''' toggles the adaptive font setting. When this is on, text in graphs will resize as the graph window changes heights. 
* '''Axis title formatting''' changes the font formatting for axis titles. 
* '''Axis title font size''' changes the font size for axis titles and key titles only 
* '''Axis label font size''' changes the font size for axis labels and key labels only 

Changing these selections will update the default graph settings accordingly. These settings will also be exported if you choose to [[Themes Library#Export Anastyle|export an Anastyle]] using the library.

Click the Result icon ([[File:VirtButtonBareIcon6.0.png]]) for each graph type to see an example.

== Set all nodes to default color and border styles ==
At the bottom right of the '''Themes Library''' is a '''Set all nodes to default color and border styles''' button. Nodes with explicit colors and styles will not update when model defaults are changed. This button reset all nodes with explicit colors and styles so they will use the defaults, ''i.e.'', the colors from the selected theme, again. 

== Export Anastyle ==
At the bottom right of the '''Themes Library''' is an '''Export Anastyle''' button. Clicking on this button will save the current model's default diagram and graph theme options into an [[Anastyles|Anastyle]] file that can be imported into other models. This way you can easily import your selected options into other models without having to import the '''Themes Library''' and select your options again. You can import an Anastyle file to a model the same way you would add a Library into a model.

See [[Anastyles]] for more information.

== Additional Settings ==
[[File:Colorthemeslibrary additionalsettings.png|617x617px]]

The '''Additional Settings''' module is located on the right hand side of the library under the example nodes. Open this module to access Arrow Settings and Corner Settings. 

=== Arrow Settings ===
The Arrow settings menu allows you to change the default size and color of arrows. 

Use the '''Arrow size''' drop-down select menu to change the arrow size.

Change the arrow color by changing the color of the '''Arrow color''' node, then pressing the '''Apply color''' button beneath it. Your selected color will not be applied as the default color until you press the '''Apply color''' button. Note that you must be in Edit mode to change the Arrow color node. If you are in Edit mode, you can open the Color Palette by right-clicking on the Arrow color node and selecting Show/Hide Color Palette.

=== Corner Settings ===
The Corner Settings menu allows you to change the default corner radius of certain objects. 

Use the '''Set corner radius to''' drop-down select menu to select a corner radius. The Null option selects the system default corner radius. 

Use the '''For object types''' multi-choice select menu to select which objects the corner radius settings should apply to. Options include Text nodes, Frame nodes, User inputs and outputs, and Buttons.

== Reverting to the Classic Theme ==
If you’re using the '''Themes Library''' and would like to go back to the Classic Analytica theme, you can simply select the Classic diagram colors and graph theme options.

Analytica also comes with the default Classic theme saved as an [[Anastyles|Anastyle]] file. You can use this file to revert any model to the Classic Theme without importing the '''Themes Library''' using the following steps:

# Go to '''File''' > '''Add Library…'''
# This should open the '''Select Library File''' window. By default this should be open in the '''Libraries''' folder. If not, this '''Libraries''' folder is usually accessible by going to C:/Program Files/Lumina/Analytica/Libraries. 
# Open the '''Node Styles''' folder.
# Select the '''Defaults.anastyle''' file and press '''Open'''.
