The attribute Loc in legend() is used to specify the location of the legend. Default value of loc is loc=”best” (upper left).
How do you specify a legend in Matlab?
Alternatively, you can specify the legend labels using the DisplayName property. Set the DisplayName property as a name-value pair when calling the plotting functions. Then, call the legend command to create the legend. Legends automatically update when you add or delete a data series.
How do I change the legend position in octave?
Implementation Note: A legend is implemented as an additional axes object of the current figure with the “tag” set to “legend” . Properties of the legend object may be manipulated directly by using set . Create a text object with text string at position x , y , ( z ) on the current axes.
What is legend in octave?
Legend entries may be specified as individual character string arguments, a character array, or a cell array of character strings. If the handles, hobjs , are not specified then the legend’s strings will be associated with the axes’ descendants. legend works on line graphs, bar graphs, etc.
How do you plot octave?
Plot using Octave When plotting in Octave you plot points having their x -values stored in one vector and the y -values in another vector. The two vectors must be the same size. Octave inserts lines between the points. If you want a smoother graph, make a longer x -vector.
How do you add a legend to an octave plot?
legend (MATLAB Functions) legend places a legend on various types of graphs (line plots, bar graphs, pie charts, etc.). For each line plotted, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify.
What is the use of legend () function?
represent the string whose contents are `parrot’ . Strings in Octave can be of any length. Since the single-quote mark is also used for the transpose operator (see section Arithmetic Operators) but double-quote marks have no other purpose in Octave, it is best to use double-quote marks to denote strings.
Is Octave a string?
Octave can display more than one plot in a single figure. The simplest way to do this is to use the subplot function to divide the plot area into a series of subplot windows that are indexed by an integer. For example, subplot (2, 1, 1) fplot (@sin, [-10, 10]); subplot (2, 1, 2) fplot (@cos, [-10, 10]);
How do you plot two functions on the same graph in octave?
These functions have the same graph. For example, The functions f(x)=x3/x and g(x)=x4/x2 have the same domain (set of non-zero real numbers), and give the same output for every input value. These are identical functions (equal functions) and generate the same graph.
What are two or more functions on the same graph?
Toggle or set the “hold” state of the plotting engine which determines whether new graphic objects are added to the plot or replace the existing objects. Retain plot data and settings so that subsequent plot commands are displayed on a single graph. Line color and line style are advanced for each new plot added.
How do you hold on in octave?
To conclude, “hold on” is to wait, or grip while “hold off” is to postpone, cancel or stop an action.
What is the difference between hold off and hold on?
What is the difference between hold on and hold all? Explanation: Both hold on and hold all commands are used to hold the graph of a function. There is no difference between them. To avoid confusion, one can only write hold to hold a graph and again enter the command hold to release the graph.
What is the difference between hold on and hold all?
To have two plots superimposed over one another, use the hold function. For example, hold on; x = -10:0.1:10; plot (x, sin (x)); plot (x, cos (x)); hold off; displays sine and cosine waves on the same axes.
How do you close an octave plot?
Draw a 2-D scatter plot. A marker is plotted at each point defined by the coordinates in the vectors x and y . The size of the markers is determined by s , which can be a scalar or a vector of the same length as x and y . If s is not given, or is an empty matrix, then a default value of 8 points is used.
How do you plot in Octave online?
Example 7 : We can change the axis values of any plot using the axis() function. Here the first 2 parameters shows the range of the x-axis and the next 2 parameters shows the range of the y-axis. We can close a figure/plot using the close command. Example 9 : We can visualize a matrix using the imagesc( ) function.
How do I edit an octave plot?
octave#:#> plot(x,y,’b–‘,’linewidth’,3) will plot x and y as a thick, blue, dashed line. The next example consists in plotting two different functions on the same axis. Specifically, we will plot the functions f1(x) = sin(x) and f2(x) = sin(x2) from x = 0 to x = 2π, using equally spaced points on the x-axis.
How do you plot equations in octave?
plot( X , Y ) creates a 2-D line plot of the data in Y versus the corresponding values in X . If X and Y are both vectors, then they must have equal length. The plot function plots Y versus X . 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.
