Fplot Title

• Plot Title X Vs Y
• Plot Title Python

1. Combining plots with combineplots. Ggstatsplot contains a “helper” function named combineplots to help you combine several plots into one plot or add a combination of title, caption, and annotation texts with suitable default parameters.
2. Plot f = e x sin (2 0 x) using fplot. Show the bounds of f by superimposing plots of e x and -e x as dashed red lines. Set the title by using the DisplayName property of the object returned by fplot.
3. The aim of this tutorial is to describe how to modify plot titles (main title, axis labels and legend titles) using R software and ggplot2 package. The functions below can be used.

Plot the following mathematical functions using the 'fplot' and 'subplot' functions of MATLAB for MATLAB domains -21title of the top plot should include the mathematical function and type of function on the top line and the MATLAB domain (as a string) on a second. Function File: h = title Specify the string used as a title for the current axis. An optional list of property/value pairs can be used to change the appearance of the created title text object. If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca.

The aim of this article is to show how to modify the title of graphs (main title and axis titles) in R software. There are two possible ways to do that :

• Directly by specifying the titles to the plotting function (ex : plot() ). In this case titles are modified during the creation of plot.
• the title() function can also be used. It adds titles on an existing plot.

The following arguments can be used :

• main: the text for the main title
• xlab: the text for the x axis label
• ylab: the text for y axis title
• sub: sub-title; It’s placed at the bottom of x-axis

The following parameters can be used to change the colors :

• col.main: color the main title
• col.lab: color of the axis titles (x and y axis)
• col.sub: color of the sub-title

Note that, the different colors available in R software are described here.

The graphical parameters to use for customizing the font of the titles are :

• font.main: font style for the main title
• font.lab: font style for the axis titles
• font.sub: font style for the sub-title

The value of these arguments should be an integer.

The possible values for the font style are :

• 1: normal text
• 2: bold
• 3: italic
• 4: bold and italic
• 5 : Symbol font

Use the R code below to create a plot title with bold and italic font style.

font size can be modified using the graphical parameter : cex. The default value is 1. If cex value is inferior to 1, then the text size is decreased. Conversely, any value of cex greater than 1 can increase the font size.

The following arguments can be used to change the font size :

• cex.main : text size for main title
• cex.lab : text size for axis title
• cex.sub : text size of the sub-title

An example is shown below :

title() can be also used to add titles to a graph.

A simplified format is :

Example of usage

Note that, the R par() function can be used to change the color, font style and size for the graph titles. The modifications done by the par() function are called ‘permanent modification’ because they are applied to all the plots generated under the current R session.

This analysis has been performed using R statistical software (ver. 3.1.0).
