Figure 99: Line charts<br />

Scatter or XY charts<br />

Scatter charts are great for visualizing data that you have not had time to analyze, and they may<br />

be the best for data when you have a constant value against which to compare the data; for<br />

example, weather data, reactions under different acidity levels, conditions at altitude, or any data<br />

which matches two series of numeric data. In contrast to line charts, the x-axis are the left to right<br />

labels, which usually indicate a time series.<br />

Scatter charts may surprise those unfamiliar with how they work. While constructing the chart, if<br />

you choose Data Range > Data series in rows, the first row of data represents the x-axis. <strong>The</strong><br />

rest of the rows of data are then compared against the first row data. Figure 100 shows a<br />

comparison of three currencies with the Japanese Yen. Even though the table presents the<br />

monthly series, the chart does not. In fact the Japanese Yen does not appear; it is merely used as<br />

the constant series that all the other data series are compared against.<br />
