The following example demonstrates the concept − Example You can draw multiple graphs on the same plot. MATLAB generates the following graph − Drawing Multiple Functions on the Same Graph The axis square command generates a square plot. The axis equal command allows generating the plot with the same scale factors and the spaces on both axes. The grid on command allows you to put the grid lines on the graph. The title command allows you to put a title on the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. 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.
MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph
#Matlab plot code
Please note that as we decrease the increment, the graph becomes smoother.Ĭhange the code file a little, reduce the increment to 5 − In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Let us take one more example to plot the function y = x 2. When you run the file, MATLAB displays the following plot − Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.Ĭreate a script file and type the following code − Here we discuss an introduction to Matlab Plot Colors, along with color code table and respective examples.To plot the graph of a function, you need to take the following steps −ĭefine x, by specifying the range of values for the variable x, for which the function is to be plottedįollowing example would demonstrate the concept. There could be instances when we have to plot multiple functions in a single plot, in such cases, colors become very handy to differentiate between different functions. MATLAB can be used to plot our data for visualizing and intuitively understanding it. Observe in the output that we have obtained a scatter plot of red color, as passed by us in the input argument. Observe in the code that we have passed pre-defined color code for red as an argument (Please refer to the table at the end of the article for pre-defined color codes)
Observe in the code that we have passed pre-defined color code for green as an argument (Please refer to the table at the end of the article for pre-defined color codes)įor this example, we will scatter plot of red color Let us first define an array to create a Bar plot:
#Matlab plot how to
How to Set the Color of Bar Plots?įor this example, we will create a bar plot with bars of green color. Observe in the code that we have passed pre-defined color codes as arguments (Please refer to the table at the end of the article for pre-defined color codes) How our input and output will look like in MATLAB console?Įxplanation: As we can see in our output, we have got our functions in the colors as passed by us in the input. Note: For this example, we will be creating our functions in following colors: 1 st function in Green, 2 nd function in Blue and 3 rd function in Yellow] example: plot(X, a, ‘g’, X, b, ‘b’, X, c, ‘y’)
