The below code is written to generate the plot for the given function expression with editing representation of the graph by including title, x,y labels and tick values. XLim 2 ; nx. There are various attributes that are supported by fplot to edit the display of the plot.

The major attributes are described in the below table:. The resultant plot generated from the method fplot for the functions pt and qt is presented with a modified line width value 2. The smoothness, accuracy, and speed of the drawing of the plot are controlled by the option MeshDensity which is the count for evaluation points.

The method fplot also supports plotting multiple functions in one single frame by splitting the layout into the same number of cells. Re-evaluation on Zoom: The plot generated from the fplot can be reevaluated by using the zooming feature.

It helps the user to reveal the hidden details in the plot. In casefplot f syntax or any of its variation is used, then returned object is of type FunctionLine objects whereas in case of fplot funx,funy syntax,the object return type is ParameterizedFunctionLine. Thus the function fplot in MATLAB supports advanced plotting features for any kind of function or expressions along with providing a wide range of customization flexibility.

This is a guide to Matlab fplot. Here we discuss the methods to know, with examples to implement with additional notes in detail. Parametric input for y-axis, specified as a symbolic expression or function. Range of values of parameter t , specified as a vector of two numbers.

Axes object. If you do not specify an axes object, then fplot uses the current axes gca. Line style, marker, and color, specified as a character vector or string containing symbols. The symbols can appear in any order.

You do not need to specify all three characteristics line style, marker, and color. For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line. Example: '--or' is a red dashed line with circle markers. Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1, The function line properties listed here are only a subset.

For a complete list, see FunctionLine Properties. Number of evaluation points, specified as a number. The default is Because fplot uses adaptive evaluation, the actual number of evaluation points is greater.

Display asymptotes at poles, specified as 'on' or 'off' , or as numeric or logical 1 true or 0 false. A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The asymptotes display as gray, dashed vertical lines. Line color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color.

The intensities must be in the range [0,1] ; for example, [0. A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes ' FF' , ' ff' , ' F80' , and ' f80' are equivalent. Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Example: ' FF'. If the line has markers, then the line width also affects the marker edges. The line width cannot be thinner than the width of a pixel. If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide. Marker symbol, specified as one of the values listed in this table. By default, the object does not display markers. Specifying a marker symbol adds markers at each data point or vertex.

Marker outline color, specified as 'auto' , an RGB triplet, a hexadecimal color code, a color name, or a short name. The default value of 'auto' uses the same color as the Color property. Marker fill color, specified as 'auto' , an RGB triplet, a hexadecimal color code, a color name, or a short name.

The 'auto' value uses the same color as the MarkerEdgeColor property.
