The first and second elements specify the lower and upper limits for the x axis. Plot a surface given matrices x , and y from meshgrid and a matrix z corresponding to the x and y coordinates of the mesh. The columns of y are plotted versus the corresponding columns of x and errorbars are drawn from the corresponding columns of error parameters. The semilogy function ignores the imaginary component in all other uses of this function. Direct link to this comment: If only one argument is supplied, then it must be a three digit value specifying the location in digits 1 rows and 2 columns and the plot index in digit 3. Produce a two-dimensional plot using a log scale for the x axis. It plots the columns of Y versus their index.
Other devices are supported by “convert” from ImageMagick. This allows you to execute a series of plot commands and have all the lines end up on the same figure. The simplest form is. The gset and gshow commands allow you to set and show gnuplot parameters. Set up a plot grid with cols by rows subwindows and plot in location given by index. The option ax can precede any of the input argument combinations in the previous syntaxes.
The variable s is a scalar defining a scaling factor to use for the arrows of the field relative to the mesh spacing. When gplot is used to plot a column vector, the indices of the elements are taken as x values.

Note the use of the function meshgrid to create matrices of X and Y coordinates to use for plotting the Z data. A plot must exist before legend is called. Plot a stem graph and return the handles of the line and marker objects used to draw the stems.
If no filename is specified, output is sent to the printer. If you don’t want the baseline and stems, then why not just use the plot command? This default is reasonable for slow terminals or hardcopy output devices because even when you are adding additional lines with a replot command, gnuplot always redraws the entire plot, and you probably don’t want to have a completely new plot generated every time something as minor as an axis label changes.
Tips If you do not specify a color when plotting more than one line, semilogy automatically cycle through the colors and line styles in the order specified by the current axes ColorOrder and LineStyleOrder properties. The x and y values can be specified separately. The simplest form is. It can also be ‘Times-Roman’. Values outside this range are clamped to the first and last colormap entries. Based on your location, we recommend that you select: Plot a surface given matrices xand y from meshgrid and a matrix z corresponding to the x and y coordinates of the mesh.
Description semilogy plots data with logarithmic scale for the y -axis. The third and fourth specify the limits for the y axis, and the fifth and sixth specify the limits for the z axis. If an axes handle is passed as the first argument, then operate on this axes rather than the current axes. The default line style is “-” and the default marker is “o”. Other MathWorks country sites are not optimized for visits from your location.
When returning only 2 arguments, return matrices corresponding to the x and y coordinates of a mesh. You may receive emails, depending on your notification preferences.
The default value is “gnuplot”. The optional return value h provides a list of handles to the the parts of the vector field body, arrow and marker. Type system “convert” to see what formats are available. Set up a plot grid with cols by rows subwindows and plot in location given ploh index. If a marker is specified then markers at the grid points of the vectors are printed rather than arrows.

If you already have a plot displayed, use the command replot to redisplay it with the new title. Multiple property-value pairs may be specified, but they must appear in pairs. Each expression may have its own set of qualifiers.
Compute isolines countour lines of the matrix z. Produce two-dimensional plots on double logarithm axis with octav.
Property-value pairs following label may be used to specify the appearance of the text. The file produced by epslatexstandalone can be processed directly by LaTeX.

The columns of y eemilog plotted versus the corresponding columns of x and errorbars are drawn from the corresponding columns of error parameters. Note that in Octave 2.
