Colour Distribution

A Colour Distribution element allows you to create a controlled, linear gradient in the Hue, Saturation or Brightness of a specific colour. The following tab sheets have to be filled out for this element:

Tab sheet: Basics

1.	Click the Basics tab sheet.

2.	Determine the orientation of the Colour Distribution by clicking on of the radio buttons.

3.	Click Apply.

Tab sheet: Position

1.	Click the Position tab sheet.

Decide whether you want the learner to be able to move the Colour Distribution during runtime. You can choose to allow motion horizontally (in x-direction), vertically (y-direction) or both, by clicking the regarding check box under Can be dragged during runtime. Just choose None if you do not want the learner to be able to interfere with the position of the Colour Distribution during runtime (default).

3.	Decide if the x-coordinate should be a Fixed number, or if you want to make it dependent on one of your model's parameters.

4.	When you have chosen for a moving Colour Distribution, choose the variable you want to link to the x-position. Enter a factor with which the value of your variable should be multiplied (optional, default = 1).

5.	Repeat from step 3 to link a variable to the position on the vertical axis.

6.	Click Apply.

Tab sheet: Anchor

1.	Decide if you want the origin of your coordinate system to be at the Center (default), or the Top - Left, Top - Right, Bottom - Left or Bottom - Right corner of the Colour Distribution.

2.	Click Apply.

Tab sheet: Size

1.	Click the Size tab sheet.

2.	Decide whether you want the Colour Distribution to have a Fixed width or if you want to link this width to a variable from your model by clicking the check box.

3.	When you have chosen for a variable width, choose the variable you want to use from the pull-down list. Enter a factor with which the value of your variable should be multiplied (optional, default = 1). For a fixed size, just enter a number.

4.	Repeat from step 2 to set the height of the Colour Distribution.

5.	Click Apply.

Tab sheet: Line Width

1.	Decide whether you want the border of the Colour Distribution to have a Fixed width or if you want to link this width to a variable from your model by clicking the check box.

2.	When you have chosen for a variable width, choose the variable you want to use from the pull-down list. Enter a factor with which the value of your variable should be multiplied (optional, default = 1). For a fixed Line Width, just enter a number.

3.	Click Apply.

Tab sheet: Colour Range

1.	Click the Colour Range tab sheet.

2.	Choose a colour model: RGB (default), CMY or HSB.

3.	Decide which of the colour-parameters you want to change.

4.	Choose the variable you want to link to this change. Optionally, set a factor with which you want to multiply the value of this variable. Click here for more information on using colour models.
