Ellipse

An ellipse is an oblong closed curved line. In an animation, you can change its shape, angle, location, size, and colours when you link it to a (changing) model variable.

2.	Set the Start Angle. With the default start angle, the ellipse is drawn from the point (radius, 0). A positive angle is clockwise in this case.

3.	Decide if you want the start arrow of the ellipse to have a simple, filled, dot, or no arrow

4.	Set the Sweep Angle. The default Sweep Angle is 360 degrees, which means a full circle is drawn. Some examples: 180 degrees means half a circle is drawn clockwise, -90 degrees results in a quarter circle, drawn counterclockwise.

5.	Decide if you want the stop arrow of the ellipse to have a simple, filled, dot, or no arrow

2.	Decide if you want the Start Angle to be a Fixed number, or if you wish to make it dependent on the value of one of the variables of your model, by ticking the check box. With the default start angle, the ellipse is drawn from the point (radius, 0). A positive angle is clockwise in this case.

3.	If you choose to use a variable Start Angle, select a variable from the drop-down menu and enter an optional factor with which you want to multiply the value of this variable. If using a Fixed Start Angle, just enter a number.

4.	Decide if you want the Sweep Angle to be a Fixed number, or if you wish to make it dependent on the value of one of the variables of your model, by ticking the check box. The default Sweep Angle is 360 degrees, which means a full circle is drawn.

5.	If you choose to use a variable Sweep Angle, select a variable from the drop-down menu and enter an optional factor with which you want to multiply the value of this variable. If using a Fixed Sweep Angle, just enter a number.

Decide whether you want the learner to be able to move the Ellipse 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 Ellipse 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 variables.

4.	When you have chosen for a moving Ellipse, 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).

2.	Decide whether you want the Ellipse 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.

1.	Decide whether you want the border of the Ellipse 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.

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.
