  1. In matlab, the scale is called the c-axis. In order to manipulate the scale, you must manipulate the c-axis values.
  2. type in the command window:
  3. caxis([0 0.1]) or whatever you want you scale limits to be.

How do you make a log-log plot in MATLAB?

Plot Multiple Lines Create a vector of x-coordinates and two vectors of y-coordinates. Plot two lines by passing comma-separated x-y pairs to loglog . Alternatively, you can create the same plot with one x-y pair by specifying y as a matrix: loglog(x,[y1;y2]) .

How do you do log 10 in MATLAB?

Y = log10( X ) returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X , the log10 function returns complex values.

How does a logarithmic scale work?

A logarithmic scale is a nonlinear scale often used when analyzing a large range of quantities. Instead of increasing in equal increments, each interval is increased by a factor of the base of the logarithm. Typically, a base ten and base e scale are used.

What does Semilogx function do in MATLAB?

semilogx( X , Y ) plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and a linear scale on the y-axis. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

How to plot log MATLAB?

Line color can be red,blue-green,cyan,magenta,yellow,black,white and no color.

  • There are two color modes that can be assigned according to the requirements.
  • There are various line styles that can be changed as per the business requirement.
  • There are two types of line style mode which have the same working mechanism as that of color style mode.

    • How to plot semilog MATLAB?

    semilogx(Y) creates a plot using a base 10 logarithmic scale for the x-axis and a linear scale for the y-axis. It plots the columns of Yversus their index if Ycontains real numbers. semilogx(Y)is equivalent to semilogx(real(Y), imag(Y))if Ycontains complex numbers. semilogxignores the imaginary component in all other uses of this function.

    How to plot two figures in MATLAB?

    Combine Plots in Same Axes. By default,new plots clear existing plots and reset axes properties,such as the title.

  • Display Multiple Axes in a Figure.
  • Create Plot Spanning Multiple Rows or Columns.
  • Modify Axes Appearance.
  • Control Spacing Around the Tiles.
  • Display Shared Title and Axis Labels.

    • How to plot single points in MATLAB?

    Matlab’s default plotting command, plot (x,y), connects the points created from list x and y with line segments. If you plot enough points, you will get a smooth looking curve, as shown in Figure 4 (b), but if you don’t plot enough points, then plot (x,y) will produce a kinky plot like the one shown in Figure 4 (c).
