Graph Setting Associations

If you change the style, font, or background settings of a graph, that change will apply to any uncertainty view of that variable. But, if you select the line style for a PDF view of a variable, it will usually not apply to the CDF view of that variable. If you change the axis range of a scale, it will still apply to that dimension if you pivot the graph or swap horizontal and vertical scales.

More generally, each graph setting has an association that control what different graph views it applies to. Usually, you don't have to think about these associations. Analytica just does what you expect. But, occasionally you may need to understand them so you can predict their effects, especially when saving defaults for a model or defining a template.

There are four types of association, controlling what types of graph a change to a graph setting applies to:

Global Associations: Appearance settings, such as colors, style, font, and background are global -- meaning that a change to one graph for a variable will apply to all graph views of that variable; clicking "Set default" button, will apply these settings to all graphs in the model that use defaults for those settings.

Result Associations: These settings apply only to the specific graph, and no other graphs, even if you click "Set Default".

Dimension Associations: Settings in the Axis Ranges tab, including range, reverse order, categorical, or log scale, apply to the specified dimension or index. When you pivot the graph, or swap horizontal and vertical, they still apply to that dimension. If you click "Set default" after changing settings for a scale that is an index variable, those settings will become the default for that index in all graphs that use that index.

Uncertainty view Associations: The application of Line style and related settings on the Chart Type tab is different for categorical and continuous graphs, and may differ by uncertainty view (PDF, CDF, Confidence Bands, etc.).

Whether the X-axis dimension is categorical or continuous determines whether a graph is considered categorical or continuous. (If SwapXY is on, then it is the Y-axis that determines this). Separate line-styles are maintained for the categorical case and the continuous case. Therefore, if you pivot a graph, causing the X-axis to change from a continuous dimension to a categorical one, the graph settings can swap from a line-graph to a bar graph, for example. (only the line-style depends on the categorical / continuous distinction).

Settings in this category are associated with a view mode. Mid, Mean and Bands all share the same association, so a setting for Mid will transfer to a graph of Mean. Separate settings exist for stats view, continuous PDF, continuous CDF, discrete prob mass, discrete cum prob, and sample. There is a separate line style for the continuous and categorical case for each of these views. But all other settings in this category, such as Area fill, change only with the view mode. (so you can't have a filled line for continuous mean and unfilled line for categorical mean, but you could have an unfilled line for mean and a filled line for PDF).

Finally, when a line style is set to Bar, the graph is required to be categorical. A flag indicates whether the continuous style setting has been set to bar, and if so, a continuous X-axis is forced to categorical when the graph is rendered.

Max Symbol Size	Sys Var	Graph_maxSymbolSize	Global	For variable symbol size
Axis Ranges:
Dimension range settings (for Index values)	Attribute	Att_graphIndexRange	Dimension	For case when Va1 has self-index, used for the self-index. ver, cat,auto, includezero, log, reverse, incs, min, max where:  ver : Must be 1 (version)  cat : Categorical flag (1=force categorical interp), opt.  auto : Full autoscale flag  includezero : force 0 to be in range flag  log : log scaling flag  reverse : reverse order flag  incs : Number of increments  min : minimum value for manually scaled axis  max : maximum value for manually scaled axis  catPos: 1=The preceeding «min», «max» are the position of categorical values. 0=They are the actual value (usually a real number).
Dimension range settings (for non-index values)	Attribute	Att_graphValueRange	Dimension	Axis settings for value dimensions. When a variable has a self-index, both its index and its value may be separately used in graphing roles, so this attribute has the settings for the value, whereas Att_graphIndexRange has the axis settings for the self-index. The field here are the same as for Att_graphIndexRange. In addition, multiple value settings may appear, separated by a bar (|) character. After the first, each successive settings is first preceeded by a number and a colon, followed by the same fields as in Att_graphIndexRange. The number corresponds to a position in the Att_GraphSetupSlices attribute. These multiple settings are used to store the axis ranges for comparison slices in an XY-plot, so that if you are plotting Va1[J='x'] vs Va1[J='z'], the axis ranges for x can tracked separately from the axis ranges for z. The very first field (before the first bar) is not preceded by a number and colon, and is used for the main result when not a comparison slice (including the case where it is sliced to do index slicers other than the comparison index).
Result slices	Attribute	Att_graphSetupSlices	View	A list of slices that have, or may have, axis settings in Att_graphValueRange. It is a bracketed list, here the first entry is the number of slots per item as is usually 3. (Although this could vary by Analytica release due to enhancements). When this is a 3, the next 3 entries are the first item, with components «idv», «ind» and «posv». «idv» is the id that appears before the colon in Att_GraphSetupSlices. «ind» is the comparison index that this applies to, which can be either a global index indentifier or Sys_LocalIndex('name') for a local index. «posv» is the 1-based slice number along the comparison index.
