There are various functions that you can use to plot data in matlab. Note that the distributionspecific function normpdf is faster than the generic function pdf. By default, matlab clears the figure each time you call a plotting function, resetting the axes and other elements to prepare the new plot.

When you add data to a plot, the title and axis labels become blank strings to avoid labeling confusion. If x or y is a matrix, then the vector is plotted versus the rows or columns of the matrix, whichever line up. Matlab is a highlevel technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. This table classifies and illustrates the common graphics functions.
It you do not have access to this function, you could use the following equation for computing the theoretical pdf. Lognormal probability density function matlab lognpdf.

After you import data into the matlab workspace, it is a good idea to plot the data so that you can explore its features. The linestyleorder property contains a cell array of character sequences, where each character sequence corresponds to a line style or a line style combined with a marker. If the plot objects support line styles and markers, matlab also cycles through the list in the linestyleorder property of the axes.
