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’
Scatter(X,Y) draws the markers in the default size and color. C can also be a color string (see ColorSpec for a list of color string specifiers) When C is a length(X)-by-3 matrix, it specifies the colors of the markers as RGB values. When C is a vector the same length as X and Y, the values in C are linearly mapped to the colors in the current colormap. If S is a scalar, MATLAB draws all the markers the same size.Ĭ determines the colors of each marker. S can be a vector the same length as X and Y or a scalar. S determines the area of each marker (specified in points ^2). Scatter(X,Y,S,C) displays colored circles at the locations specified by the vectors X and Y (which must be the same size).
