How do I change the individual bar colors of my bar chart in Grapher?

Grapher offers two ways to change the individual bar colors on a bar chart: using a color table or using a color column.

Method 1: Color Table

Use a color table to set define a number of colors that are used to fill each bar in order. Any number of colors can be defined  The colors in the table are repeated if there are more bars than defined colors by default.

  1. Create a bar chart by clicking the Home | New Graph | Bar | Vertical Bar Chart (Grapher 12 Bar Chart) command.
  2. Click the Bar Chart in the Object Manager to select it.
  3. In the Property Manager, click on the Fill tab.
  4. Check the box next to Use color table. The bar chart will change to a variety of default colors.
  5. Click Set button next to the Color table command.
  6. In the Color Table dialog, make any changes to customize the individual bar colors or patterns. The colors will appear in the order they are listed on the left side of the dialog. To change a color or pattern, click on the color on the left side and make changes on the right side of the dialog.
  7. Click OK to update the plot.

 

Method 2: Color Column

Use a Color column to designate a specific color for each bar in your data file. In addition to the information to create the bar chart, an additional Color column in the worksheet is needed. This column must contain the color name, such as Blue, Cyan, or Red. The bar created by that row in the worksheet is colored based on the color name.

  1. Create a bar chart by clicking the Home | New Graph | Bar | Vertical Bar Chart (Grapher 12 Bar Chart) command.
  2. Click the Bar Chart in the Object Manager to select it.
  3. In the Property Manager, click on the Fill tab.
  4. Click None next to Color variable and select the worksheet color name column. The bars are each filled appropriately.
  5. To determine appropriate color names, click on any filled object in Grapher. On the Fill tab in the Property Manager, click the color next to the Foreground color option. Select the desired color and the color name is shown.
