Chapter 7 Creating Charts from Data 161
Here are ways to change the look of selected data point symbols and lines using
the Chart inspector:
To adjust a symbol’s size, make a selection from the Data Symbol pop-up menu and
m
then enter a value or use the stepper in the adjacent field.
To connect the points of the selected series with a straight or curved line, select an
m
option 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 line
m
that you want to change, and then open the Graphic inspector. (Note that you can
change the colors separately for the data points, line, and trendline, 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 of the Graphic inspector. Enter a value or use the
stepper in the adjacent field to adjust the line thickness.
In scatter charts, you can display error bars for both x and y axis measurements. To
understand more about showing error bars, see “Showing Error Bars in Charts” on
page 151. To learn about other formatting options, see “Formatting Charts” on page 143.
Customizing 2-Axis and Mixed Charts
Both 2-axis and mixed charts feature two data series, each one represented as a
column, line, or area chart. The Chart inspector provides controls that allow you to
format each of the axes individually.
Two-axis charts represent the two data series as two charts, using a different value axis
(y axis) for each chart. The axis on the left side of the chart belongs to the first data
series and is called Value Axis (Y1). The axis on the right side of the chart belongs to
the second data series and is called Value Axis (Y2).
