Graph Setting Associations

Each graph setting has a particular type of association. There are three types of associations. The associations determine how the setting transfers when a graph is pivoted, dimensionality changes, or the view mode changes (e.g., from PDF view to Bands view). The association scheme has been created to allow the default settings to do the right thing in most cases and minimize the need for a user to have to change graph settings every time a simple view or pivot change is enacted. When you Set Default, or define a template, it may be necessary to understand the associations to understand what will be impacted.

Types of Associations

Global Associations

Settings having a global association apply to the graph as a whole. If "Set Default" is used, the setting transfers to all graphs. General appearance characteristics usually fall into this category, such as colors, fonts, effects, etc.

Result Associations

These apply only to the result graph, and do not transfer to other graphs even if "Set Default" is pressed.

Dimension Associations

Range settings are associated with a specific dimension. For example, if you set a manual scaling range for Index I, that range will continue to apply to I, and only to I, as the graph is pivoted. Dimension associations include the manual range settings, and flags for autoscaling, log-scaling, reverse-order, categorical, and include-zero.

When "Set Default" is used, a dimension-association will apply to any graph that uses that particular dimension. If "Apply" is used, the setting will apply onto to that dimension and only within the current result graph.

View Associations

Line style and related chart-type settings have a fairly complex association that depends on the view mode and whether a graph is categorical or continuous.

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 continuouse 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.
