Chapter 11: Temporal Analysis<br />

Ordered layout The Ordered layout evenly spaces out all of the items on your chart from left to<br />

right. This layout operates on all chart items, whether or not they are controlling.<br />

Proportional<br />

layout<br />

The Ordered layout is useful when:<br />

• you have imported a volume of data and need to apply an initial layout<br />

• analyzing high volumes of data, particularly that with date and time<br />

• presenting and printing<br />

Ordered layouts almost always take up less room left to right on a chart than<br />

Grouped By Time or Proportional layouts.<br />

When you apply an Ordered layout the distance between adjacent items is fixed; it<br />

does not take into account the date and time of items. The resulting chart,<br />

therefore, will be displayed non-proportionally.<br />

In the example below, items that are an hour apart have the same gap between<br />

them as items that are a day or a month apart. The flow of time is adjusted while<br />

the distance between items remains constant.<br />

The Proportional layout lays out items on the chart with a uniform distance for time<br />

intervals. Items with date and time are spaced apart exactly as they are in relation<br />

to each other in time.<br />

The Proportional layout is most useful:<br />

• for visualizing busy and slack periods and contrasting their relative durations<br />

• when you have a chart with a sequence of happenings<br />

It displays an accurate representation of when items occur in relation to each<br />

other. This can help you see how happenings occur in real time, but it can<br />

result in very wide charts with items spaced far apart.<br />

• when importing data, for example telephone data<br />

• provide an initial view of how the data is structured, before applying other<br />

layouts<br />
