# How do you plot different colors on a graph in MATLAB?

## How do you plot different colors on a graph in MATLAB?

1. plot(thisX, thisY, ‘-‘, ‘Color’, thisColor, ‘LineWidth’, 2);
2. hold on; % Leave plots up so we’ll see all of them at the end.
3. grid on;
4. xlabel(‘x’, ‘FontSize’, 20);
5. ylabel(‘y’, ‘FontSize’, 20);
6. title(‘Demo by Image Analyst’, ‘FontSize’, 20);

## How do you plot multiple lines in MATLAB?

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.

How do you add color to a plot in MATLAB?

You can also change the color, line style, and marker by setting properties on the object after creating it. For example, this code creates a line and then changes it to a green dashed line with circular markers. p = plot([0 1 2]); p. Color = ‘g’; p.

How do you color a line in MATLAB?

Specify Line Width, Marker Size, and Marker Color Create a line plot and use the LineSpec option to specify a dashed green line with square markers. Use Name,Value pairs to specify the line width, marker size, and marker colors. Set the marker edge color to blue and set the marker face color using an RGB color value.

### How do you plot a 3d line in MATLAB?

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

1. To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length.
2. 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.

### How do you add a plot to an existing graph?

Summary

1. Drag and drop dataset into the the graph layer. You can add data to a graph by drag-and-drop.
2. Use Plot Setup dialog to add the plot.
3. Use Layer Contents dialog to add the plot.
4. Use Copy Plot button in mini toolbar to add a existing plot into the graph layer.

How do I plot multiple lines in Matplotlib?

Python Code Editor:

1. import matplotlib. pyplot as plt.
2. x1 = [10,20,30]
3. y1 = [20,40,10]
4. plt. plot(x1, y1, label = “line 1”)
5. x2 = [10,20,30]
6. y2 = [40,10,30]
7. plt. plot(x2, y2, label = “line 2”)
8. plt. xlabel(‘x – axis’)

How do you plot more than one line on a graph in Matlab?

1. x1=[2 3 4 5];
2. y1=[9 4 3 2];
3. x2=[11 20 30 50 ];
4. y2= [ 20 30 50 60];
5. plot(x1,y1)
6. hold on.
7. plot(x2,y2)
8. hold off.

## Can we have multiple 3d plots in Matlab?

Can we have multiple 3d plots in MATLAB? Explanation: The plot3() function is a pre-defined function in MATLAB. So, it will allow the use to generate multiple 3d plots. This is inherent to the system.

## When to use different colors in MATLAB plots?

When you plot multiple data sets together in the same axes, MATLAB ® automatically assigns different colors (and possibly line styles and markers) to the plot objects. You can customize the colors, line styles, and markers when you call plotting functions. For example, this code plots a solid red line and a dashed green line with circular markers.

How can I plot multiple lines in different colors using loops?

My code plots all the lines the same color. At first my legend was not matching the lines so I am trying to plot the lines with defined colors and then change my legend accordingly. If anyone knows why the legends colors are out of order with the plot that would also help! Cs is the function that varies with time.

How to plot a scalar line in MATLAB?

If one of X or Y is a scalar and the other is either a scalar or a vector, then the plot function plots discrete points. However, to see the points you must specify a marker symbol, for example, plot(X,Y,’o’). plot(X,Y,LineSpec) sets the line style, marker symbol, and color.

### When to use line styles and markers in MATLAB?

When you plot multiple data sets together in the same axes, MATLAB ® automatically assigns different colors (and possibly line styles and markers) to the plot objects. You can customize the colors, line styles, and markers when you call plotting functions.
