Help Center Help Center. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Use this syntax as an alternative to specifying coordinates as matrices. You can specify LineSpec for some x - y pairs and omit it for others.

Help Center Help Center. Visualize 10 strongest SURF features, including their scales and orientation which were determined during the descriptor extraction process. Points object,specified as an M -by-2 matrix of M number of [ x y ] coordinates, or as one of the point feature objects described in Point Feature Types. The object contains information about the feature points detected in the input image. To obtain points, use the appropriate detect function that pairs with the point feature type. Handle to use for display. You can set the handle using gca. Name-value arguments must appear after other arguments, but the order of the pairs does not matter. Before Ra, use commas to separate each name and value, and enclose Name in quotes. Display scaled circle, specified as true or false. When you set this value to true , the object draws a circle proportional to the scale of the detected feature, with the feature point located at its center. When you set this value to false , the object turns the display of the circle off. The algorithm uses this equivalent size of circular area to compute the orientation of the feature. Display feature point orientation, specified as true or false. When you set this value to true , the object draws a line corresponding to the point's orientation.

Extended Capabilities Tall Arrays Calculate with arrays that have more rows than fit in memory. Example: plot tbl,["x1","x2"],"y" specifies the table variables named x1 and x2 for the x -coordinates, matlab plotting points. Create a line plot of both sets of data and return the two chart lines in p.

Help Center Help Center. To plot one set of coordinates, specify x and y as vectors of equal length. To plot multiple sets of coordinates on the same set of axes, specify at least one of x or y as a matrix. To use the same size for all the circles, specify sz as a scalar. To plot each circle with a different size, specify sz as a vector or a matrix. You can specify one color for all the circles, or you can vary the color.

A picture is worth a thousand words, particularly visual representation of data in engineering is very useful. Students are encouraged to study that section; what follows is a brief summary of the main plotting features. Probably the most common method for creating a plot is by issuing plot x, y statement where function y is plotted against x. This opens a menu from which we choose plot x,y. See the figure below. Graphs without labels are incomplete and labeling elements such as plot title, labels for x and y axes, and legend should be included. Using up arrow, recall the statement above and add the annotation commands as shown below. If you want to merge data from two graphs, rather than create a new graph from scratch, you can superimpose the two using a simple trick:. Multiple plots in a single figure can be generated with subplot in the Command Window. However, this time we will use the built-in Plot Tools.

Then create a scatter plot of four points using those colors. You can specify one color for all the circles, or you can vary the color. Edited: Walter Roberson on 24 Jan For a complete list, see Line Properties. Plot SURF features. Use s to modify properties of a scatter chart after creating it. Version History Introduced in Rb. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. Example: plot tbl,"x",2 specifies the second variable for the y -coordinates. When you specify your data as a table, the axis labels and the legend if present are automatically labeled using the table variable names. Points object,specified as an M -by-2 matrix of M number of [ x y ] coordinates, or as one of the point feature objects described in Point Feature Types. Any valid combination of vectors or matrices described for x and y. Search Support Clear Filters.

Use s to set properties after creating the plot. Create Line Plot From Matrix. The table variables you specify can contain numeric, categorical, datetime, or duration values. To plot all circles with the equal area, specify sz as a numeric scalar. Desired Marker Sizes x and y sz Example Same size for all points Any valid combination of vectors or matrices described for x and y. Example: plot tbl,["x1","x2"],"y" specifies the table variables named x1 and x2 for the x -coordinates. For example, after plotting, call the xlabel or legend function with the desired label strings. If Y is a matrix, the plot contains one line for each column in Y. Version History Introduced before Ra expand all Rb: Plots created with tables preserve special characters in axis and legend labels When you pass a table and one or more variable names to the scatter function, the axis and legend labels now display any special characters that are included in the table variable names, such as underscores. Example: plot tbl,"x",vartype "numeric" specifies all numeric variables for the y -coordinates. You have a modified version of this example.
