Graphs let you communicate statistical information in a visual way. In Adobe Illustrator, you can create nine different types of graphs and customize them to suit your needs. Click and hold the graph tool in the Tools panel to see all different types of graphs you can create.
Drag diagonally from the corner where you want the graph to begin to the opposite corner. Alt‑drag (Windows) or Option‑drag (Mac OS) to draw the graph from its center. Hold down Shift to constrain the graph to a square.
Click where you want to create the graph. Enter a width and height for the graph, and click OK.
Note: The dimensions you define are for the main body of the graph and do not encompass the graph’s labels and legend.
Adjusting the column width has no effect on the width of columns in the graph; it only lets you view more or fewer digits in a column.
With the default value of 2 decimals, the number 4 entered in a cell appears in the Graph Data window box as 4.00, and the number 1.55823 entered in a cell displays as 1.56.
You use the Graph Data window to enter the data for your graph. The Graph Data window appears automatically when you use a graph tool and stays open until you close it.
A. Entry text box B. Import data C. Transpose row/column D. Switch x/y E. Cell style F. Revert G. Apply
Select a cell in the worksheet, and enter the data in the text box at the top of the window. Press Tab to input the data and select the next cell in the same row; press Enter or Return to input the data and select the next cell in the same column; use the arrow keys to move from cell to cell; or simply click another cell to select it.
Copy data from a spreadsheet application such as Lotus® 1‑2‑3 or Microsoft Excel. In the Graph Data window, click the cell that will be the upper‑left cell of the data you paste, and choose Edit > Paste.
Use a word-processing application to create a text file in which the data for each cell is separated by a tab, and the data for each row is separated by a paragraph return. The data can only contain decimal points or decimal commas; otherwise, the data is not plotted. (For example, enter 732000, not 732,000.) In the Graph Data window, click the cell that will be the upper‑left cell of the data you import, click the Import Data button , and select the text file.
If you accidentally enter graph data backward (that is, in rows instead of columns, or vice versa), click the Transpose button to switch the columns and rows of data. To switch the x and y axes of scatter graphs, click the Switch X/Y button .
Labels are words or numbers that describe two things: the sets of data you want to compare, and the categories across which you want to compare them. For column, stacked column, bar, stacked bar, line, area, and radar graphs, you enter labels in the worksheet as follows:
A. Data set labels B. Blank cell C. Category labels
For column, stacked column, bar, stacked bar, line, area, and radar graphs, enter labels in the worksheet as follows:
If you want Illustrator to generate a legend for the graph, delete the contents of the upper‑left cell and leave the cell blank.
Enter labels for the different sets of data in the top row of cells. These labels will appear in the legend. If you don’t want Illustrator to generate a legend, don’t enter data‑set labels.
Enter labels for the categories in the left column of cells. Categories are often units of time, such as days, months, or years. These labels appear along either the horizontal axis or vertical axis of the graph, with the exception of radar graphs, for which each label results in a separate axis.
To create labels consisting only of numbers, enclose the numbers in straight quotation marks. For example, enter "1996" to use the year 1996 as a label.
To create line breaks in labels, use the vertical bar key to separate lines. For example, type Total|subscriptions|1996 to produce the following graph label:
A scatter graph differs from the other kinds of graphs in that both axes measure values; there are no categories.
Enter data‑set labels in every other cell along the top row of the worksheet, starting with the first cell. These labels will appear in the legend.
Enter y‑axis data in the first column and x‑axis data in the second column.
You organize data sets for pie graphs similarly to other graphs. However, each row of data in the worksheet generates a separate graph.
Enter data‑set labels as for column, stacked column, bar, stacked bar, line, area, and radar graphs. Enter category labels if you want to generate graph names.
To create a single pie graph, plot only one row of data, either all positive or all negative values.
To create multiple pie graphs, plot additional rows of data, either all positive or all negative values. By default, the size of the individual pie graphs is proportional to the total of each graph’s data.
After you enter the labels for your graph, you’re ready to enter each set of data under the appropriate column.
Column, stacked column, bar, stacked bar graphs
The height of the column or length of the bar corresponds to the amount being compared. For column or bar graphs, you can combine positive and negative values; negative values appear as columns extending below the horizontal axis. For stacked column graphs, numbers must be all positive or all negative.
Each column of data corresponds to one line in the line graph. You can combine positive and negative values in a line graph.
Values must be all positive or all negative. Each row of data entered corresponds to a filled area on the area graph. Area graphs add each column’s values to the previous column’s totals. Therefore, even if area graphs and line graphs contain the same data, they appear substantially different.
Each number is plotted on an axis and connected to the others in the same axis to create a “web.” You can combine positive and negative values in a radar graph.
Graphs can be formatted in a variety of ways. For example, you can change the appearance and position of the graph’s axes, add drop shadows, move the legend, and combine different graph types. You can view the formatting options for a graph by selecting a graph with the Selection tool and choosing Object > Graph > Type.
You can also manually customize your graph in numerous ways. You can change the colors of shading; change the typeface and type style; move, reflect, shear, rotate, or scale any or all parts of the graph; and customize column and marker designs. You can apply transparency, gradients, blends, brush strokes, graphic styles, and other effects to graphs. You should always apply these types of changes last, because regenerating the graph will remove them.
To get ideas for how you can customize graphs, see the examples in the Cool Extras/Sample Files/Graph Designs folder inside the Illustrator application folder.
Keep in mind that a graph is a grouped object that is related to its data. Never ungroup the graph; if you do, you cannot change the graph. To edit a graph, select the parts you want to edit without ungrouping the graph, using either the Direct Selection tool or the Group Selection tool.
It is also important to understand how elements of a graph are related. The entire graph with its legends is one group. All the sets of data are a subgroup of the graph; in turn, each set of data with its legend box is a subgroup of all the sets of data. Each value is a subgroup of its set of data, and so on. Never ungroup or regroup objects that are within the graph.
In the Graph Type dialog box, click the button that corresponds to the desired graph type, and click OK.
Once graph objects are painted with gradients, changing graph types can cause unexpected results. To prevent undesirable results, either do not apply gradients until the graph is finished, or use the Direct Selection tool to select gradient-painted objects and paint those objects with a process color; then reapply the original gradients.
With the exception of pie graphs, all graphs have a value axis which displays the unit of measurement for the graph. You can choose to display the value axis on one side or both sides of the graph. Bar, stacked bar, column, stacked column, line, and area graphs also have a category axis which defines the categories of data in the graph.
You can control how many tick marks appear on each axis, change the length of tick marks, and add a prefix and suffix to numbers on the axis.
To format tick marks and labels, select an axis from the pop‑up menu at the top of the dialog box, and set the following options:
Determines the placement of tick marks on value axes, left axes, right axes, bottom axes, or top axes. Select Override Calculated Values to manually calculate the placement of tick marks. Either accept the values set when you created the graph or enter a minimum value, a maximum value, and the number of divisions between labels.
Determines the length of tick marks and number of tick marks per division. For category axes, select Draw Tick Marks Between Labels to draw tick marks on either side of the labels or columns, or deselect the option to center tick marks over the labels or columns.
If your graph has a value axis on both sides, you can assign a different set of data to each axis. This causes Illustrator to generate a different scale for each axis. This technique is especially useful when you combine different graph types in the same graph.
For column, stacked column, bar, and stacked bar graphs, you can adjust the amount of space between each column or bar in the graph. You can also adjust the amount of space between the categories, or clusters, of data in the graph. For line, scatter, and radar graphs, you can adjust the appearance of lines and data points.
To adjust the space between columns and bars in a column, stacked column, bar, or stacked bar graph, enter a value between 1% and 1000% in the Column Width, Bar Width, or Cluster Width text box.
A value greater than 100% causes the columns, bars, or clusters to overlap one another. A value less than 100% leaves space between the columns, bars, or clusters. A value of 100% moves the columns, bars, or clusters flush against each other.
You can access general graph options by selecting the graph with the Selection tool and double-clicking the graph tool in the Tools panel.
Add Drop Shadow
Applies drop shadows behind the columns, bars, or lines in a graph, and to entire pie graphs.
Add Legend Across Top
Displays the legend horizontally across the top of the graph instead of to the right of the graph.
First Row In Front
Controls how the categories, or clusters, of data in a graph overlap when the Cluster Width is greater than 100%. This option is the most useful when working with column and bar graphs.
First Column In Front
Places the column, bar, or line that corresponds to the first column of data in the Graph Data window on top. This option also determines which column is on top for column and stacked column graphs with a Column Width greater than 100% and for bar and stacked bar graphs with a Bar Width greater than 100%.
Draws lines that extend across the graph, from left to right along the horizontal (x) axis. This option is not available for scatter graphs.
Draw Filled Lines
Creates a wider line according to the value you enter in the Line Width text box, and which fills the line with paint according to the specifications for that series of data. This option becomes available when you select Connect Data Points.
By default, the legend is displayed to the right of the graph. However, you can choose to display it horizontally across the top of the graph.
You can change the placement of the legend and how wedges are sorted in pie graphs. You can also specify how you want to display multiple pie graphs.
To change the placement of the legend, select an option for Legend.
To specify how multiple pie graphs are displayed, select an option for Position.
To specify how wedges are sorted, select an option for Sort.
Tip: Percentages and legends are painted black by default. If a pie wedge with a dark background obscures a legend, repaint the dark background. Use the Group Selection tool to select the dark pie wedges, and paint the wedges using the Color panel or Swatches panel.
You can combine different graph types in one graph. For example, you may want one set of data to appear as a column graph and other sets of data to appear as a line graph. You can combine any type of graph with any other, with the exception of scatter graphs. Scatter graphs cannot be combined with any other graph type.
If a graph uses more than one graph type, you may want one set of data along the right axis and the other set of data along the left axis. In this way, each axis measures different data.
If you use stacked column graphs with other graph types, be sure to use the same axis for all sets of data that are represented by stacked column graphs. If some sets of data use the right axis while others use the left, the column heights may be misleading or may overlap.
- Without moving the Group Selection tool pointer from the legend, click again. All of the columns grouped with the legend are selected.
You can also select a group by clicking one of its parts, clicking again to select columns grouped with it, and clicking a third time to select the legend. Each click adds another layer of grouped objects to the selection, beginning with the next group up in the hierarchy. You can click as many times as the number of groups to add to a selection.
Illustrator uses a default font and font size when generating text for the graph’s labels and legend. However, you can easily change the formatting of type to add visual interest to your graph.
You use graph designs to add illustrations to columns and markers. Graph designs can be simple drawings, logos, or other symbols representing values in a graph; they can also be complex objects that contain patterns and guide objects. Illustrator comes with a variety of preset graph designs. In addition, you can create new graph designs and store them in the Graph Design dialog box.
You can apply graph design to columns in several ways:
Uniformly scaled design
Is scaled both vertically and horizontally. The horizontal spacing of the designs is not adjusted for the different widths.
Stacks a design to fill the columns. You can specify the value that each design represents, as well as whether you want to chop or scale designs that represent fractions.
Is similar to a vertically scaled design, except that you can specify where in the design to stretch or compress it. For example, if you were using a person to represent data, you might stretch or compress only the body, but not the head. Using the Vertically Scaled option would scale the entire person.
Illustrator comes with a variety of preset designs that you can use in your graphs. You can also transfer the graph designs you create between documents.
To import preset graph designs, navigate to the Cool Extras/Sample Files/Graph Designs folder inside the Illustrator application folder. Then select a graph designs file, and click Open.
To import graph designs from another document, select the document, and click Open.
Initially, all that appears is a new panel with colors, gradients, and patterns from the imported file. However, the imported graph designs will be available when you open the Graph Column or Graph Marker dialog box.
- Click and type a percent sign (%) followed by two digits from 0 to 9. The digits control how the data is displayed.
The first digit determines how many places appear before the decimal point. For example, if your total was 122, a digit of 3 would display 122. If you enter 0 for the first digit, the program adds the number of places necessary for the value.
The second digit determines how many places appear after the decimal point. Zeros are added as necessary, and values are rounded up or down as necessary. You can vary these numbers, depending on how many digits you need.
If you choose the Repeating Column Type, enter a value in the Each Design Represents text box. Also select whether to chop or scale any fractions of the design from the For Fractions pop‑up menu. Chop Design cuts off a fraction of the top design as necessary; Scale Design scales the last design to fit in the column.
You can reuse a graph design that you created and edit it to make a new design. If you have the original artwork, you can alter it and then rename the design using the Graph Design dialog box.
If you don’t have the original artwork defined as a graph design, you can retrieve the original by pasting the graph design into your artwork.
