#MATLAB COLORS CODE#
The below MATLAB code is designed to create semi logarithmic pseudo color plot and to alter the appearance using surface object properties from its return value.Įxplanation: The resultant output is surface plot where y-coordinate input is the logarithmic function of x-coordinate inputs. The MATLAB plotting function pcolor() can also be used to create semi logarithmic pseudo color plot. The color representation of the faces are modified due to modification applied to the surface object property ‘facecolor’ for the surface object ‘s’. The below code snippet is designed to create the pseudo color plot and modify the face color of the cells using interpolated coloring using surface object properties.Ĭmat = Įxplanation: The resultant pseudo color plot is assigned to surface object ‘s’. The edge color and the line width of the plot is modified using ‘s’ value as shown in the output plot.
The below code is developed create a pseudo color plot for input matrix and modify the edge color and line width after the plot is generated.Įxplanation: The resultant pseudo color plot is assigned to variable ‘s’.
This return value can be used to customize the properties of the plot after its creation. When pcolor() method is assigned to a variable, it returns a surface object. The below code is wriiten to create 1X2 chart layout and creating two different pseudo color plot for two different set of inputs and functions in each cell of the layout.Įxplantion: The resultant plots are arranged in single layout consisting of two tiles generated using the function nexttile(). MATLAB supports tilling of plots using the functions like nexttile() and tiledlayout(). The data from the input matrix are represented by different color code in the plot. Example #3Ĭreate pseudo color plot for the input matrix data Cmat within the defined x and y coordinates given by matrix inputs X and Y.Įxplanation: The resultant plot has the vertices as per the values given by X and Y matrices and data from Cmat is plotted within the limits. Generate Hadamard square orthogonal matrix and create pseudo color plot for same,with the origin set in the upper left corner.Įxplanation: The resultant graph is a 40X40 two-color map, represented in the reverse direction. The pseudo color plot also can be created in the reverse direction using axis function. Here are the examples mentioned: Example #1Ĭreate pseudo color plot for input matric Cmat.Įxplanation: The input matrix is of size 2X3 and the vertices of the plot is decided 2X3 as default data. Here is the table of Attributes: Attribute S=pcolor(_) Attributes of Matlab pcolor() To store the pseudo color plot as surface object You can learn more about this topic at matwork.Hadoop, Data Science, Statistics & othersĪx defines the axes targeted for the plot Use the following code to try it out x = -pi:pi/10:pi The axes are counted along the top row of the Figure window, then the second row, etc. H = subplot(m,n,p), or subplot(mnp), breaks the Figure window into an m-by-n matrix of small axes, selects the p-th axes for the current plot, and returns the axes handle. Subplot helps have plots side by side on the same sheet. Plot(x,y2,'b','LineWidth',2) Matlab subplot One of the many ways to plot multiple functions on the same plot is to use hold on or insert the corresponding equations in the plot code. The Graph Plotting multiple graphs on the same plot Here is another example which you can learn a lot from
#MATLAB COLORS HOW TO#
Here is how to change the thickness of the line of your plot in Matlab

Just like it is to change the color of your plot in Matlab, the same goes for changing the line style, increasing the thickness of the line or some other aspect of it You must surely have grasped how to add the color code to get your graph to the wanted color, and notice at the beginning of this post the different color and code you can make use of while using this technique Matlab plotting line style Let’s twist the code a little to change the plot color
