There are various plots available in MATLAB that can be used to represent data in graphical form. This section illustrates some common plots and their functions to get the used.

Line Plots

Line plots gives a useful way to compare sets of data or track changes over time. User can plot the data in a 2-D or 3-D view using either a linear or a logarithmic scale. Also, user can plot expressions or functions over specific intervals.

Data Distribution Plots

Visualize the data distribution using plots such as histograms, pie charts, or word clouds. For example, use a histogram created to group data into bins and display the number of elements in each bin.

Discrete Data Plots

Helps in Visualization of discrete data using plots such as stem plots, bar graphs. For example, user can make a vertical or horizontal bar graph where the bar lengths are proportional to the values that they represent.

Polar Plots

Plots in polar coordinates

polarplot Plot line in polar coordinates
polarscatter Scatter chart in polar coordinates
polarhistogram Histogram chart in polar coordinates
compass Plot arrows emanating from origin
ezpolar Easy-to-use polar coordinate plotter

Contour Plots

2-D and 3-D isoline plots

Contour Contour plot of matrix
contourf Filled 2-D contour plot
contourc Low-level contour plot computation
contour3 3-D contour plot
contourslice Draw contours in volume slice planes
clabel Label contour plot elevations
fcontour Plot contours

Vector Fields

Comet, compass, feather, quiver and stream plots

Feather Plot velocity vectors
quiver Quiver or velocity plot
compass Plot arrows emanating from origin
quiver3 3-D quiver or velocity plot
streamslice Plot streamlines in slice planes
streamline Plot of 2-D or 3-D vector data to streamlines

Surface and Mesh Plots

Representing gridded data as surface and mesh plots

surf Surface plot
surfc Contour plot below a 3-D shaded surface plot
surface Create surface object
surfl Surface plot with colormap-based lighting
surfnorm Compute and display 3-D surface normals
mesh Mesh plot
meshc Plot a contour graph under mesh graph
meshz Plot a curtain around mesh plot
hidden Remove hidden lines from mesh plot
fsurf Plot 3-D surface
fmesh Plot 3-D mesh
fimplicit3 Plot 3-D implicit function
