Histogram

Histogram is representing distribution of data. Each column of the histogram is proportional to quantity it represents.

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 diagram type, the list of levels and level elements. Use + button to add as many elements as needed. Dialog window opens up.

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

Name - short text inside the element.

LIMITATION. The size of the text area 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 element.

Display from the start allows to display this element 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 Axes tab you can redefine parameters of diagram axes.

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),

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.
