29 How To Label Curves In Matlab
MATLAB Script . The stress strain curve for the aluminum in tension and compression examples can be seen in Figures 1 and 2. The following MATLAB script will plot the stress-strain curve for either case, provided the LAMMPS datafile and this script are located in the same directory. Note that values are negative in the compressive case. Specify the labels in a cell array. x1 = linspace(0,5); y1 = sin(x1/2); plot(x1,y1) hold on x2 = [0 1 2 3 4 5]; y2 = [0.2 0.3 0.6 1 0.7 0.6]; scatter(x2,y2, 'filled' ) hold off legend({ 'sin(x/2)' , '2016' }, 'Location' , 'northwest' , 'Orientation' , 'horizontal' )
Essentially, I want the curves to be automatically labeled from one of the associated vector names. Specifically the x-axis vector name, so when I view or share the plot, the legend will have each curve labeled appropriately. Currently, I am using the Plot Browser window pane in the Plot Tools view to manually label each curve.
Control Value in Exponent Label Using Ruler Objects. Plot data with y values that range between -15,000 and 15,000. By default, the y-axis tick labels use exponential notation with an exponent value of 4 and a base of 10.Change the exponent value to 2. Set the Exponent property of the ruler object associated with the y-axis.Access the ruler object through the YAxis property of the Axes object. Plotting curves: ezplot, ezplot3 We begin with an example of 2-D graphics using ezplot to plot the graph y = x + 2sin(2x) on the interval 0 ≤ x ≤ 10. For simple functions that can be easily written in one line of code we pass the Matlab expression, enclosed in single quotation marks, as the first input argument to ezplot.The optional second argument specifies the plotting limits for the ... Bézier Curves and Kronecker's Tensor ProductLast time we talked about Martin Newell's famous teapot. Today we're going to talk about the curves which the teapot is made of.

You can also add the previous plot to the same graph by using function hold on. If you need help with any command type help command name in the command window. I have the following graph (and 2 similar ones) as shown below which I generated with MATLAB: Rather than having a legend, I would like to have the curves labelled, so for exapmple in maths font you have 'Kn=0.0' floating somewhere below the blue curve, then a black line connects that to the curve, and so on for the others. hi, can anyone suggest how to write matlab code for BER vs Eb/No curve for hamming(7,4) coding and golay (24,12) code.

Reissuing the xlabel command replaces the old label with the new label.
Find Intersections - an engineering approach. The problem of how to find intersections of given lines is very common in math or basic algebra.. The meaning of those intersections is that the given lines or curves have the same coordinate values at some points. In other words, those lines or functions have simultaneously the same x and y (or even z) values at those points called intersections. Add Title and Axis Labels to Chart. Create Simple Line Plot. Create x as 100 linearly spaced values between and . Create y1 and y2 as sine and cosine values of x. Plot both sets of data. Add Title. Add Axis Labels. Add Legend. Change Font Size.

MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph.

Problem displaying labels in legend – fit curve overwrites data labels; Drawing a line without creating a legend entry; How to draw a dotted lsline; Hi, Can someone tell me how to remove (data1 that caused by the reference line) from legend; Using markers for data, lines for simulations The legend is used to label the different data curves when more than one curve is drawn on the same plot. The syntax is legend('label1','label2',...) Where label1, etc are strings used to create the legend. This video shows how to put an individual text label on each of a series of points. This video also shows a simple technique for understanding lines of code where there are many functions acting as inputs to other functions.

Explanation: Notice on the top right side of the plot, we have got the names of our functions. Example #3 Next, what if we don't want our labels to be on the top right but in some other place on the plot. Let us learn how to achieve that. Legend function in MATLAB allows us to put our label in place of our choice. All we need to do is pass the pre-defined code for the direction, as an argument.
