Using Broadcast Arcs
These broadcast arcs are developed so that they convey a few different broadcast messages:
- fast signals – use the variations with many broadcast arcs
- slow signals – use the variations with few broadcast arcs
- signals that maintain their intensity after they leave the origination point – use the variations with the same line size for all arcs
- signals that fade after they leave the origination point – use the variations with arcs that become are less distinct
- signals that are strongest in the center of the direction they are pointed – use the variations with the ends of the arcs faded
All of these variations imply a specific type of signal. Identify the type of broadcast you wish to convey, review the characteristics of each download, and choose the variation(s) that best illustrate your message.
The broadcast tower is included with each download, but you don't need to use it. Instead, consider using your logo, an image of a product, or other object or photograph that is "sending a message."
Power Chart 'Animated Broadcast Technique' is closely related to this series, although it uses filled circles and animation to convey the broadcast concept. These broadcast arcs don't need to be animated, although they certainly may be.
V11, V12, and V13 are segments fields that are enclosed and can accept all types of fills – color, gradient, photograph, pattern (in PowerPoint 2003). They may not be the best choices for to illustrate a broadcast, but they are useful in other instances.
Customizing the Broadcast Arcs
If you want to change the size/shape of the arcs, be sure to group it and resize the entire group. Once resized, ungroup to proceed with other customizations. V07-V13 can receive line point formatting – increase/decrease the point size for all of the lines or graduate the line sizing.
V01-V06 are uneditable except for recoloring as a photograph in PowerPoint 2007 and 2010. V07-V10 are lines only and can receive any line colors; and, if you're using PowerPoint 2007 or 2010, they can receive a gradient.
It's probably not useful to use 3D with these frameworks.
Broadcast waves don't have shadows, so it's probably best to avoid using shadows.
Gradients, patterns, and pictures
Gradients can be applied to the lines in V07-V13 if you are using PowerPoint 2007 or 2010. Gradients, patterns, and pictures can be added to V11-V13 if you're using PowerPoint 2003. Gradients and pictures can be added to V11-V13 if you're using PowerPoint 2007 or 2010.
Since the arcs broadcast from a specific point, they should appear in sequence. The way that this is handled depends on which type of arc layout you're using.
- If you're using the half-circle arcs, then it's probably best to animate each arc to appear one after the other.
- If you're using the the 45-degree quarter-circle arcs, it's best to animate each arc to appear one after the other.
- If you're using the 45-degree rotated arcs, you can animate each arc to appear one after the other or you can group them and wipe them in from the origination direction. If the broadcast tower is on the left, wipe them in from the left.
Download the animated example to see an example animation scheme. An alternative to the animation scheme used in the example scheme might be to group the two arc broadcasts and animate as a zoom. Format the zoom to repeat as many times as you like, until the next click, or to the end of the slide.
