Function Name: Plot
Purpose: Drawing
Usage: Plot (x, Y, ...)
Parameters
1. Symbols and lines
PCH: Specifies the symbol used to draw the point, the range of values [0, 24], where 4 is the "difference", 20 is the "point"
CeX: Specifies the size of the symbol. CeX is a numeric value that represents a multiple of the PCH, which is 1.5 times times the default
Lty: Specifies the line type. Lty=1 represents a solid line, 2 to 6 are dashed, the degree of emptiness is not the same
LWD: Specifies the line width, the default value is lwd=1, can be modified 1.5 times times, twice times, etc.
2. Color
Col: default drawing color. Some functions, such as lines, pie, can accept a vector containing a color value and automatically recycle it.
For example: Col=c ("Red", "blue") need to draw three lines, then three colors are red, blue, red
Col.axis: The color of the axis scale text , not the color of the axis
Col.lab: Color of the axis label (name)
Col.main: Color of title
Col.sub: The color of the subtitle
FG: The foreground color of the graph
BG: Background color for graphics
3. Text attributes (used to specify font size, font, typeface)
Cex.axis: Scale multiples of axis scale text
Cex.lab: The zoom factor of the axis label (name)
Cex.main: The zoom multiplier of the title
Cex.sub: The scale multiplier of the subtitle
Font: Integer. Lets you specify a font style. 1 Regular, 2 bold, 3 italic, 4 bold italic
4. Graphic dimensions and graphics boundaries
Pin: Indicates the width and height of the graphic in inches
Mai: Represents the boundary size as a numeric vector, in the order of "bottom, left, top, right", in inches
Mar: The size of the boundary as a numeric vector, in the order of "bottom, left, top, right", in English, the default value C (5, 4, 4, 2) +0.1
5. Title
You can use the function title, in the following format:
Title (main = "", Sub = "", Xlab = "", Ylab = "")
You can also directly put the parameters inside the title directly in plot ()
6. Axes
Plot parameter
Axes=false will disable all axes, frame and scale are all gone
Xaxt= "n" Disables tick marks on the x-axis
Yaxt= "n" disables the tick marks on the y-axis
You can also customize by using the Axis function Axis (...)
Side: An integer. Represents the drawing axis on which side of the graph (1=, 2 = left, 3 = on, 4 = right)
at: A numeric vector that indicates the placement of the tick mark that needs to be plotted
Labels: a character vector (which can also be numeric) that represents the text label (the scale value) next to the tick mark, and if the whole is not written, use the at value directly
Col: Color of lines and ticks
Lty: Line type
Las: Whether the label's font is parallel (=0) or vertical (=2) axis
TCK: The length of the tick mark (Default-0.01, negative value indicates the scale is outside the graph, positive value indicates the scale is inside the shape)
7. Reference line
Abline (H=yvalues, V=xvalues)
Example: Plot (1:10)
Abline (H = C (1, 5)) #则在y = 1 and 5 each have a horizontal line
Abline (v = C (1, 5)) #则在x = 1 and 5 each have a vertical line
8. Legend (Legend)
Legend (location, title, Legend, ...)
