MATLAB SCATTER PLOT HOW TO
MATLAB SCATTER PLOT CODE

Observe in the output that we have obtained a scatter plot of red color, as passed by us in the input argument.

MATLAB SCATTER PLOT CODE

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 SCATTER 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. Here we discuss the Uses of MATLAB with the Description of Scatter Plots. You may also look at the following article.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’) This is a guide to Scatter Plots in Matlab.

And yes, if all the values are scattered and don’t follow any pattern, we can be sure that there is hardly any relation between the variables that we are using.

Similarly, in the example that we have used, we are able to visualize the linear relationship between the variables.

It also helps to visualize the outliers in data.

For example, a scatter plot with values concentrated at a particular area signifies that a lot of values in the data set belong to that area.

Scatter plots can be used to visualise if any relation exists between the values of the data.

Scatter plots are very handy graphs when it comes to get the look and feel of the data by just visualizing it.

Here we can clearly see that the colour of the outline is changed and also width is now 1.5

Similarly, ‘MarkEdgecolor’ will be used to change the outline colour of the circles. Linewidth,1 will set out the outline of the circles in the plot to 1mm. This function will modify the scatter plot graph for the ‘Name’ and ‘Value ’ pair mentioned in the argument. we can get Square shape with argument ‘s’ in the function. If we need some other shape like a square, this function can be used. We just need to pass the argument ‘filled’ in the function for the circles to be filled in scatter plot graph.ĭefault shapes for scatter plots are circles. This function will help in filling the circles. Now, what if we need all these circles to be solid or in other words, filled with colours. This helps us in differentiating higher and lower values as per our need 4. We can clearly visualize circles of changing colours. And then the scatter function will help to map the elements present in c to colours present in the colormap. Here, elements present in a, b, and c will determine the location and colour of the circles.

For circles of different colours define ‘c’ as a three coloured matrix on an RGB triplet or a vector.

For circles with same colour define ‘c’ as the name of the colour of an RGB triplet.

It will help in specifying the colour as follows: This function will define the colour of the circles to be plotted in the graph. The significance of doing this is that we will get our attention diverted towards higher values immediately. We can clearly visualize that the circles in the graph are of different sizes. Let’s take the same example as in previous explanation, to keep things simple for better understanding

Different sized Circles: To create a plot with unequal sized circle define ‘z’ parameter in function to be vector and length of the vector with being equal to the length of ‘a’ and ‘b’.

Equal Sized Circles: To create a plot with equal-sized circle define ‘z’ parameter in function to be scalar.

This function will set out the circle sizes.įollowing Circle sizes can be created using this function in Graphs:

Solution: We will get the following graph in MATLAB Such type of graphs are also called as ‘Bubble Plots’Įxample: Let us define two variables a & bĪ = linspace(0, 30, 100) ī = linspace(10, 50, 100).

This function will help us to make a scatter plot graph with circles at the specified locations of ‘a’ and ‘b’ vector mentioned in the function.

Here is the description of scatter plots in MATLAB mention below 1. Now let us understand all these one by one: Description of Scatter Plots in MATLAB MATLAB provides its user with a basket of functions, in this article we will understand a powerful function called ‘Scatter Plot function’
