**mesh**( X , Y , Z ) creates a **mesh** plot, which is a three-dimensional surface that has solid edge colors and no face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y . … **mesh**( Z , C ) additionally specifies the color of the edges.

Accepted Answer **surf**() and **mesh**() both create Chart **Surface** Objects in current releases. **surf**() turns on face coloring by default and uses black edges by default, whereas **mesh**() turns face coloring off by default and uses colored edges by default.

**plot3( X , Y , Z ) plots coordinates in 3-D space.**

- To
**plot**a set of coordinates connected by**line**segments, specify X , Y , and Z as vectors of the same length. - To
**plot**multiple sets of coordinates on the same set of axes, specify at least one of X , Y , or Z as a matrix and the others as vectors.

plot3() **plots** some markers at the specified points. It does not make a solid **surface between** the markers. **surf**() will create a solid **surface between** the points.

**There are 4 main steps:**

- Establish the domain by creating vectors for x and y (using linspace, etc.)
- Create a “grid” in the xy-plane for the domain using the command meshgrid.
- Calculate z for the
**surface**, using component-wise computations. **Plot**the**surface**. The main commands are mesh(x,y,z) and surf(z,y,z)

Accepted Answer The issue occurs when the grid which your **surface** is plotted over contains a large number of points. The lines which create the wire mesh **surface** are **black** by default and take precedence over the color map. In this situation, the wire grid is so dense that the lines form a completely **black surface**.

**linspace** is similar to the colon operator, “ : ”, but gives direct control over the number of points and always includes the endpoints. “ lin ” in the name “ **linspace** ” refers to generating linearly spaced values as opposed to the sibling function logspace , which generates logarithmically spaced values.

**Plot** Multiple Lines By default, **MATLAB** clears the figure before each **plotting** command. Use the figure command to open a new figure window. You can **plot** multiple lines using the hold on command. Until you use hold off or close the window, all **plots** appear in the current figure window.

The **colon** is one of the most useful operators in **MATLAB**®. It can create vectors, subscript arrays, and specify for iterations. … A(:,n) , A(m,:) , A(:) , and A(j:k) are common indexing expressions for a matrix A that contain a **colon**.

**plot**( Y ) creates a 2-D line **plot** of the data in Y versus the index of each value.

- If Y is a vector, then the x-axis scale ranges from 1 to length(Y) .
- If Y is a matrix, then the
**plot**function**plots**the columns of Y versus their row number.

**Follow these simple steps:**

- First, find the value for x on the x-axis. …
- Next, find the y-value – in this case, y=1100, so find 1100 on the y-axis. …
- Your point should be plotted at the intersection of x=0 and y=1100. …
- Finally,
**plot**the point on your**graph**at the appropriate spot.

The first step is to make sure that the equation of the **line** is in the Slope-Intercept Form, that is y = m x + b y=mx+b y=mx+b. Start by **plotting** the y-intercept which is (0,b). Find another point using the slope m with the y-intercept at the reference point. Connect the two points with a ruler.

“We have defined a story as a narrative of events arranged in their time-sequence. A **plot** is also a narrative of events, the emphasis falling on causality. ‘The king died and then the queen died,’ is a story. ‘The king died, and then the queen died of grief’ is a **plot**.

A **line plot** is a linear **graph** that shows data frequencies along a number **line**. It can be used to analyze data that has a single defined value.

A **line plot** is a way to display data along a number **line**. … Below is an **example of a line plot** showing the distance 17 turtles traveled in an hour (we know it is 17 turtles because there are 17 dots on the **line plot**). The 3 dots above 21 mean that 3 turtles traveled a distance of 21 meters in an hour.

A **line plot** is a **graph** that shows the frequency of data occurring along a number **line**. **Line plots** provide a quick and easy way to organize data and are best used when comparing fewer than 25 different numbers.

A **line graph** (also known as a **line plot** or **line chart**) is a **graph** which uses **lines** to connect individual data points that display quantitative values over a specified time interval. **Line graphs** use data point “markers” that are connected by straight **lines** to aid in visualization.

In a literary work, film, **story** or other **narrative**, the **plot** is the sequence of events where each affects the next one through the principle of cause-and-effect. The causal events of a **plot** can be thought of as a series of events linked by the connector “and so”.

Every plot should have a **conflict**, rising action, and **climax**.
