I know I can use the Rectangle function to do so but it is a rather complex way of doing it as I would need to work out the leftmost point everytime. You can plot the data in a 2-D or 3-D view using either a linear or a logarithmic There are various functions that you can use to plot data. The details of creating a plot in MATLAB will not be addressed here. semilogx(Y) creates a plot using a base 10 logarithmic scale for the x-axis and a linear scale for the y-axis. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. Since you have the data [code ]x[/code] and [code ]y[/code], just simply call [code ][m,i] = max(y)[/code] and you will get the maximum [code ]m[/code] and the respective index [code ]i[/code]. For example, when you type datenum(‘9,15,2014’) and press Enter, you get an output value of 735857. This type of plot is appropriate, for example, when connecting data points with straight lines would give the misleading impression that the function being plotted is continuous between the sampled data points. Setting the Title, Legend Entries, and Axis Titles in MATLAB How to set the title, legend-entries, and axis-titles in MATLAB. Note that in this form of syntax, X and Y must have the same dimensions. When using datetick(), you need an axis that has numbers that are in the range of the dates you need. MATLAB® makes it easy to plot data on top of a geographic basemap inside a MATLAB figure. 1 Line plots The basic syntax for creating line plots is plot(x,y), where x and y are arrays of the same length that plot(Y) plots the columns of Y versus their index if Y is a real number. One solution is the file readColData. ) In MATLAB, plot(X, Y) simply draws points on the graph (and connects them with lines). Types of MATLAB Plots There are various functions that you can use to plot data in MATLAB ® . (Refer to ``help with downloading scripts'' for instructions on downloading this script to your computer. This example shows how to create a 2-D line plot interactively using the Plots tab in the MATLAB toolstrip.
