Bubble Series
Bubble series have three data values per series element - the first two
position the series element along the X and Y axes, and the third determines
the size of the graphical element, i.e. the bubble, displayed at this position.
Bubble series may be mixed with XY, Histogram and Scatter series.
Bubble series accept dragged colors to set the fill color or line color.
Other attributes of a Bubble series may be changed through the Bubble Series
Inspector.
Bubble Series Inspector
When a Bubble series is selected in the chart, the
Inspector displays the controls that are used to set its attributes. The Bubble Series Inspector contains a
tab view with three tabs: Style, Labels, and Shared. The contents of each of those tabs are addressed separately
below.
Style Tab
The attributes set with controls found in the tab labeled ÒStyleÓ apply only
to the currently selected series. Changing the values of these attributes does not
affect any of the other series in the chart unless they are also selected.
¥ Line Width and Color
The Line Width slider and the color well set the width and color of the lines
outlining the bubbles.
¥ Bubble Shape
Sets the style of the bubble to square or
circular.
¥ Fill Color
Sets the fill color of the bubbles.
¥ Image
A Bubble series can contain an image. The
image is set by dragging an image file into a Bubble series or by using the
Set.. button on the Inspector.
|
Set .. - Sets the image for the Bubble series through an
open panel. |
¥ Point Marker
Sets the graphic used to mark the data (X,Y) point. Useful when an unbalanced
or nonsymmetrical image is being used.
¥ Display series on Y1 / Y2 Axis
Associates the series with either the Y1 or Y2 axis (the axis must be active in
order to associate a series to it). The data range of the associated axis will
determine how the series is drawn.
Labels Tab
The contents of this tab are used to control the content, color, position and
rotation of the series labels.
¥ Labels
A switch titled ÒLabelsÓ at the top of the tab view panel will enable or disable
the series labels for the selected series.
¥ Label Content
The content of the data labels is set to:
Data - numeric labels
Text - textual labels
Text and Data - both textual and numeric values in the labels
The textual labels contain the row labels as they have been provided in the
Data View. The numeric labels are the three series element values.
¥ Label Position
Label positioning options are relative to
the bubble. Series labels can be
double- clicked to deep-select
them, then dragged freely across the chart. When this is done, the label
position is set to ÒCustomÓ.
¥ Label Color
The Label Color sets the display color of series labels.
¥ Label Rotation
The Rotation controls set the rotation of all of the series labels.
Shared Tab
These attributes are common to all Bubble series in the chart. Changing the
value for the selected Bubble series changes the value for all other Bubble
series in the chart.
¥ Z-Scale
Sets the scale by which the bubbles are
sized.
|
Independent - In this mode, the bubbles are sized relative to
one another based on their area. That is if one bubble has a Z value of 2 and
another has a Z value of 4, then the first will have half the area of the
second. The absolute size of the bubbles can be altered using the slider,
while maintaining the relative areas of all bubbles. |
