Pie Chart

Pie chart (circle diagram) is representing percent distribution of data as sectors of circle or doughnut.

This Object can save and restore its last state, i.e. when you return to the Slide this Object will display the last displayed element.

Examples of Object appearance:

Object Parameters

On the Main tab you can define the type of the diagram - pie or doughnut, sector's size calculation type, list of elements and descriptions, and type of presenting values. Sectors are displayed exactly in the order they are entered, clockwise from "north" direction. Use + button to open sector properties dialog. Sector dialog window opens up.

You can use one of predefined color schemes or select custom colors for fill, gradient and border.

Value defines angle value for this sector. Actual angle will be calculated automatically (sum of numeric values of all sectors will be treated as 360°). This value will be ignored if Equal elements size type is selected.

Name - short text on the arc inside the sector.

LIMITATION. Length of the text arc is quite small, please keep this text as short as you can. Long texts will be cut. Please use description for long texts.

Description - any rich text description, that will be displayed in special description block near the diagram.

You can also attach sound file to each sector.

Display from the start allows to display this sector in selected state when the Object is displayed (and also in Edit mode). In case more than one element has this parameter checked, only first of these elements will be selected.

On the Elements tab you can specify element's appearance parameters.

On the Description tab you can switch displaying of description blocks on and off and define its display parameters:

• Color scheme (one of predefined or custom),
• Border width,
• Gradient angle - from 0 (north direction) to 360 degrees clockwise,
• Corner radius in pixels,
• Inner padding.

Also you can define element's display parameters.

• event to start display - mouse click or mouse over,
• transition effect and its duration,
• display pointer line to element enables display of connecting line between sector and description block.

You can also specify the behavior of the Object in case nothing is selected.

On the Background tab you can switch displaying of background block on and off and define its display parameters:

• Color scheme (one of predefined or custom),
• Border width,
• Gradient angle - from 0 (north direction) to 360 degrees clockwise,
• Corner radius in pixels,
• Inner padding.

On the Sound tab you can switch click and mouseover sounds on and off, or change it to custom sounds.

IMPORTANT! Sounds must be short and have no starting lag. Otherwise it may lead to undesirable delays in course playing.

Object Events

Object is capable generating events with regards to the user's actions and interpretation of the actions by the object. When combined with actions events can be employed for building up intellectual behavior models for other objects depending on the current state of the Object. Events are available using CourseLab built-in events manipulation mechanism.

Event	Triggered Upon
on All Items Displayed	After displaying last unvisited element. If the Object is configured to restore its state then this event will be fired only once.
