MATLAB Legend and Publication Booster: Enhancing Presentation Impact with Legends in Reports and Demonstrations

# MATLAB Legends and Publishing Tools: Enhancing Presentations and Reports with Legends

## 1. Overview of MATLAB Legends

Legends in MATLAB serve as visual elements to identify different lines, markers, or areas within a graph. They provide information about the sources of data and the meanings of graphical elements to the reader.

Legends are typically located in the top right corner of the graph, containing a box with color or pattern samples for each line, marker, or area, along with corresponding labels. These labels usually represent the names of the data sources or descriptions of the graphical elements.

Legends are crucial for understanding and interpreting graphs, as they allow readers to quickly identify and differentiate between datasets. They also help organize and present information clearly, enabling readers to easily correlate data with corresponding labels.

## 2. Customizing and Beautifying Legends

Legends in MATLAB are graphical elements that explain the colors, line styles, and marker patterns of different lines, markers, or patches in a graph. By default, legends are positioned in the top right corner of the graph, but they can be customized by adjusting their location and size. Additionally, the title, labels, line styles, and colors of legends can be customized to enhance their readability and aesthetics.

### 2.1 Adjusting the Position and Size of Legends

The position of legends can be adjusted using the `legend('Location', 'location')` function, where `location` can be one of the following values:

- `'North'`: Places the legend at the top of the graph
- `'South'`: Places the legend at the bottom of the graph
- `'East'`: Places the legend on the right side of the graph
- `'West'`: Places the legend on the left side of the graph
- `'NorthEast'`: Places the legend at the top right corner (default location)
- `'NorthWest'`: Places the legend at the top left corner
- `'SouthEast'`: Places the legend at the bottom right corner
- `'SouthWest'`: Places the legend at the bottom left corner

The size of legends can be adjusted using the `legend('Position', [left, bottom, width, height])` function, where `left` and `bottom` specify the coordinates of the lower-left corner of the legend, and `width` and `height` specify the width and height of the legend.

% Create a graph
figure;
plot(1:10, rand(1, 10), 'b-', 1:10, rand(1, 10), 'r--', 1:10, rand(1, 10), 'g:');

% Adjust the position and size of the legend
legend('Location', 'NorthWest', 'Position', [0.1, 0.8, 0.2, 0.1]);

### 2.2 Setting the Title and Labels of Legends

The title of a legend can be set using the `legend(`

# 3. Applying Legends in Reports

### 3.1 Layout and Typography of Legends

In reports, the layout and typography of legends are critical as they directly affect the readability and aesthetics of the report. Here are some tips for the layout and typography of legends:

- **Vertical or Horizontal Arrangement:** Legends can be arranged vertically or horizontally depending on the overall layout of the report and spatial constraints. Vertical arrangements are typically used for longer legends, while horizontal arrangements are suitable for shorter ones.
- **Location of Legends:** Legends are usually placed below or to the right of charts to avoid obscuring the data within the charts.
- **Size of Legends:** The size of legends should match the size of the charts. Legends that are too large can be distracting, while those that are too small can be difficult to read.
- **Spacing Between Legend Elements:** There should be appropriate spacing between elements in the legend to enhance readability.

### 3.2 Annotations and Explanations in Legends

Annotations and explanations in legends can provide additional information, helping readers understand the elements within the legends. Here are some methods for adding annotations and explanations:

- **Adding Text Labels:** Text labels can be
