For this, we take a for loop with value k=4 and in that for loop we use a rand function, basically rand function is used to generate a random number it this example we take 20 random numbers, so we take rand(1,20) and these 20 random numbers are assigned to the variable d. Let us see an example, we create 4 subplots for any random values and then we replace the 4 th subplot with empty axes. Then we use a scatter function to plot a 3 rd signal, scatter plot with circles at the locations specified by the vectors x and y. And now we plot a 3 rd plot take we multiply cos(x1) signal with magnitude 4 and those values assign to 圓 variable. Then we divide cos(x1) signal by 2 and assign those values to y2 and now we use plot function with x1 and y2 variables, this plot the 2 nd signal on the same axes with a different color.
Now, we use a hold on, hold on retains plot in current axes so that the new plot added without deleting a previous plot. Then we assign a title for that plot using a title function. Then we plot a signal by taking x1 and y1 variables, we plot signal using a plot function, plot the data in y1 versus the corresponding values in x1. Firstly we take a linspace function to generate a linearly spaced vector and this assign to x1 variable and we take a cos(x1) signal on y1 variable. Le we see an example for multiple plots in matlab, in this example we take three signals on a single plot.

Or leave a comment for Pekka here.Hadoop, Data Science, Statistics & others we'll continue to consider your recommendations for Pick-of-the-Week recognition!Īs always, comments to this blog post are welcome. Please continue to steer us to your favorite File Exchange submissions. (again!) to Frank Engel for the nomination. Pekka's function affords great control beyond just making a tight array of subplots. Ha = tight_subplot(2,2,0.05,) Ĭreates a 2x2 array of axes with a normalized horizontal gap of 0.05 a vertical gap of 0.025 an equal height margin (topĪnd bottom) of 0.05 and unequal width margins-0.3 on the left, and 0.05 on the right.
And, of course, it conveniently returns a vectorīy default, the axes spacing is tighter than subplot's:Īnd you can clearly see how the function got its name.īetter still, ask tight_subplot for custom spacing: figure % ha = tight_subplot(Nh, Nw, gap, marg_h, marg_w)Īllows me to specify the number of horizontal axes, the number of vertical axes, the gap as a scalar (or as a vector of horizontalĪnd vertical gap values, ), and the height and width margins. "Tight Subplot" is not that the default axes spacing makes better use of the figure's real estate, but that it gives me complete-andĮasy-control over horizontal and vertical gap spacing, and separately, of left-and-right and top-and-bottom margin spacing. Fair enough (though with a bit of effort, one can customize the position of subplots).
(default) gaps between axes generated with the subplot command. Judging from the title of the submission, Pekka wrote and shared "Tight Subplot" because he was dissatisfied with the large Brett's Pick this week is the Tight Subplot, by Pekka Kumpulainen.
