Chapter 10 Creating Charts from Data 243

To show data point symbols:

1 Select a data series (area shape), click Inspector in the toolbar, click the Chart button,

and then click Series.

2 Choose a symbol from the Data Symbol pop-up menu.

3 Adjust the size of the data point symbols by entering a value or using the stepper in

the adjacent eld.

To learn about other formatting options, see “Formatting Charts” on page 228.

Using Scatter Charts

Scatter charts display data dierently from the other kinds of charts. They require

at least two columns or rows of data to plot values for a single data series. To show

multiple data series, you use additional two-column (or two-row) pairs.

Each pair of values determines the position of one data point. The rst data value in

the pair is the x-axis of the point. The second data value is the y-axis of the point. If

you’ve already created a chart with data points that don’t occur in pairs, and then

you change your chart to a scatter chart, Pages may not plot the data as you expect.

Depending on how the data is arranged in the table, it may not be possible to create

any plot at all. Make sure you have entered x and y point values for each data series

you want to plot before choosing to create a scatter chart.

Before you can change the look of data point symbols or lines, you must select a

symbol or line of interest, and then open the Chart inspector. (See “The Inspector

Window” on page 23 to learn about opening the Inspector.)

To change the look of selected data point symbols and lines, do any of the following:

Choose an item from the Data Symbol pop-up menu, and then adjust the symbol’s size m

by entering a value or using the stepper in the adjacent eld.

To connect the points of the selected series with a straight or curved line, choose an m

item from the Connect Points pop-up menu.

To change the color of the data points or lines in your chart, select a data point or m

line that you want to change, and then click the Graphic inspector. (Note that you can

change the colors separately for the data points, line, and trend line, even though they

represent the same data series.) In the Graphic inspector, click the Stroke color well,

and then select a color from the Colors window.

To change the style and thickness of any line in your chart, select it and then choose a m

line style in the Stroke pop-up menu. Enter a value or use the stepper in the adjacent

eld to adjust the line thickness.
