Emphasising On Hover With this option, certain bubbles can be highlighted directly without moving the mouse over them. Category Emphasis A bubble is selected based on a portion of the contents of the category label. Several selectors are possible simultaneously. The entry is made per field or as comma-separated notation. For example, if the cardinal point is part of the category label and all bubbles from west and north are to be highlighted, the value of the property would be as follows: North,West Opacity of other Bubbles This value determines to what extent bubbles that are not highlighted should be hidden. The value starts at 0.0 (completely hidden) and ranges up to 1.0 (completely visible). Annotations If this option is activated, Annotations are displayed at runtime when the mouse is moved over a bubble. Annotations are temporary labels that are connected to the bubble by lines and represent the respective value on the axis. For more tips on 'Hover', see the 'Runtime interactivity' section in the documentation.
Connection Related Bubbles If this feature is enabled, bubbles are connected in the order in which they appear in the data. This can be used, for example, to display temporal progressions or to mark the assignment of bubbles to each other more clearly. How bubbles are assigned to each other is defined by the Matcher Index. Redundant elements in the Category Label are hidden if possible and only displayed at the first element. On Hover Determines whether the bubbles should be connected initially, or (if this option is activated) as soon as a bubble is highlighted with the mouse. Matcher Index This index defines how bubbles should be assigned to each other. The value -1 means that all bubbles are connected to each other. All values from 0 to n define the position of the category label of the element to be assigned. For example, if there are two bubbles, the first one has the category label "South, Internet" and the second one "South, Computers" and you want to assign all bubbles from the south to each other, select index 0 to use the first element of the category label.
Ranges Ranges can be added to highlight complete areas of the X or Y dimensions. This is done by clicking on the +-symbol. Alternatively, one of the existing sample definitions can be activated and adjusted. The Ranges are divided into areas that should be marked on the X- or Y-dimensions. The checkbox in front of the definitions activates the respective range. Furthermore the following options are available: Enable: (De)Activates the Range. Description: Descriptions can be inserted here. Start: Defines the position as data value where the Range should start. Instead of a numerical value, the following wildcards are available: min, mean and max. This defines the minimum, average or maximum of the respective data series as the starting point of the Range. End: Defines the position as a data value at which the Range should end. Instead of a numerical value, the following wildcards are available: min, mean and max. This defines the minimum, average or maximum of the respective data series as the end point of the Range. Opacity: Sets the transparency of the Range in values from 0 (completely transparent) to 1 (not transparent). Color: Sets the color of the range.
Trend The checkbox activates the trend line. It is intended to visualize the trend of the development of the displayed data points and to make connections recognizable. This line is the regression line known from statistics, which represents the linear relationship of values in a Cartesian coordinate system. The following options are available: Color: Determines which color the trend line should have. Width [px]: Defines the width of the trend line. Correlation: Activates the display of the correlation coefficient under the legend of the bubbles. This indicates how precisely the course of the trend line can be determined. The value varies between 1 (absolutely accurate trend line) and 0 (trend line not meaningful).
Graphs For orientation in the coordinate system, various graphs can be added according to their function and then drawn. This is done by clicking on the + button. Alternatively one of the existing sample definitions can be activated and adapted. The checkbox in front of the definitions activates the respective graph. Furthermore the following options are available: Enable: (De)Activates the graph. Description: Descriptions can be inserted here. Function: The function that determines the appearance of the graph. They can be written following the specifications of expr-eval and depend on the variable x. For example x, x^2, sin(x), sqrt(x), log(x). Color: The color of the line of the graph. Width: The width of the line of the graph in pixels.
