Use chart styles in Pages on Mac
You can customise the look of a chart and create a new style from the customised chart. You can also create a new chart style that reflects the colours of an image. The new styles are saved along with the styles that come with the template, and you can apply them to other charts.
The thumbnail images at the top of the Chart tab in the sidebar represent pre-designed chart styles that are specifically made to look good with the template you’re using. You can apply a different style to a chart at any time.
Apply a different style to a chart
Save a chart as a new style
If you made changes to a chart’s look and want to save these changes, you can create a new chart style that can be used again later. You can’t add new chart styles in a document shared with others.
Go to the Pages app
on your Mac.Open a document, then click the chart that has the formatting you want to save as a new style.
In the Format
sidebar, click the Chart tab.Click the arrow to the right of the chart styles to go to the last group of styles.
Click
to add your style.In the dialogue that appears, choose an option:
All series styles: Keep all available series styles associated with the chart.
Only visible series styles: Keep only the series styles currently visible in the chart.
Click OK.
Your new chart style is added to the chart styles at the top of the sidebar. You can drag styles to organise them however you like, or replace them.
Create a chart style that uses the colours in an image
You can create a new chart style that matches the colours of a particular image. This can be helpful when you want to make a visual connection between the data shown in the chart and the subject of the image.
The new style is based on the type of chart currently showing in the sidebar, but it uses the colours of the image from which it was created.
Go to the Pages app
on your Mac.Open a document, then click a chart, or click
in the toolbar to add a chart.In the Format
sidebar, click the Chart tab.Drag an image to the chart styles in the sidebar. You can use any image on your computer.
Alternatively, you can Control-click a chart style, choose Create Style, then browse for an image.
The new chart style is added to the chart styles at the top of the sidebar. The new style doesn’t replace the style you Control-clicked.
To apply the new style to the selected chart, click the style in the sidebar.
Redefine a chart style
You can modify the look of a chart — by changing its fonts, colours and so on — then update that chart’s style to incorporate the changes. Any other charts using that style are also updated.
Go to the Pages app
on your Mac.Open a document, click a chart that uses the style you want to update, then modify its appearance so it looks the way you want.
Click the chart you just modified (if you deselected it).
In the Format
sidebar, click the Chart tab.Control-click the style, then choose Redefine Style from Selection.
If your chart has fewer than six data series, a dialogue appears. Choose an option:
All series styles: Keep all available series styles associated with the chart.
Only visible series styles: Keep only the series styles currently visible in the chart.
Click OK.
You can update charts of the same type to use the redefined style. Click the chart you want to update, then select the chart style in the sidebar.
Organise chart styles
You can change the order of the chart styles at the top of the sidebar, or delete any style.
Go to the Pages app
on your Mac.Open a document, then click any chart in the document.
In the Format
sidebar, click the Chart tab.Click and hold the style you want to move, then drag the style to a new location.
If you have multiple style panes and want to move a style from one pane to another, drag the style over the left arrow
or right arrow 
to open the other pane.
Delete a chart style
Control-click the style, then choose Delete Style.
