tailieunhanh - Lecture note Data visualization - Chapter 25

In this lecture we learned about: Function plots, three dimensional plotting, surface plotting, mesh plot, surf plot, contour plot, editing in plot in graphical window, making plot from workspace window. | Lecture note Data visualization - Chapter 25 Lecture 25 Recap Function Plots Three Dimensional Plotting Surface Plotting Mesh Plot Surf Plot Contour Plot Editing in Plot in Graphical Window Making Plot from Workspace Window Saving Plots There are several ways to save plots created in MATLAB If the plot are created with programming code stored in an M fi le simplyrerunning the code will re create the figure The figure can also be saved from the file menu using the Save As . . . option. Several choices will be opened The figure can be saved as a .fig fi le which is a MATLAB specific fi e format. To retrieve the figure just double click on the file name in the current folder. You can do the same thing programmatically with the code open The figure can be saved in a number of different standard graphics formats such as jpeg .jpg and enhanced Summary of Chapter The most commonly used graph in engineering is the x y plot This two dimensional plot can be used to graph data or to visualize mathematical functions No matter what a graph represents it should always include a title and x and y axis labels Axis labels should be descriptive and should include units such as ft s or kJ kg MATLAB includes extensive options for controlling the appearance of your plots The user can specify the color line style and marker style for each line on a graph Continued . In addition to x y plots MATLAB offers a variety of plotting options including polar plots pie charts bar graphs histograms and x y graphs with two y axes The scaling on x y plots can be modified to produce logarithmic plots on either or both x and y axes Engineers often use logarithmic scaling to represent data as a straight line The function fplot allows the user to plot a function without defining a vector of x and y values MATLAB automatically chooses the appropriate number Continued . The three dimensional plotting options in MATLAB include a line plot a number of surface plots and contour plots Most of the options .
