ASCII Graph Plotter

Plots the graph of a function with ASCII characters.

See the change log here.

How to use

py main.py [function: str] [scale: float,float] [origin: int,int] [size: int,int] [discontinuous: bool] [precision: bool] [ascii_only: bool]

Parameter	Type	Default value	Description
function	`str`		Defines the function
scale	`float,float`	`0.1,10`	Scales the graph in x,y direction
origin	`int,int`	`40,20` calculated by `(size-1)/2`	Sets the origin of the plot to the list index x,y
size	`int,int`	`81,41`	Sets the size x,y in characters of the plot
discontinuous	`bool`	`false`	Specifies if the graph should be plotted discontinuously
precision	`bool`	`false`	Specifies if the graph should be plottet with thinner characters oriented at the angle at the point
ascii_only	`bool`	`false`	Specifies whether the graph should be plotted with thinner characters, depending on the slope at each point

Built-In Functions

sin, cos, tan, cot
asin, acos, atan, acot
degrees, radian
log, sign, sqrt

Built-In Constants

e, pi

Examples

Specifie the scale in x direction as 0.2 and use the default scale in y direction of 10, so write 0.2,_
Set the x origin to the list index 5 and use the default y origin of list index 20, so write 5,_
Use the default x size of the plot of 81 and specifie the y size of the plot as 32, so write _,32
Use the default for all other parameter, so don’t write anything or use _ and _,_ as placeholder

py main.py sin(x) 0.2,_ 5,_ _,32

The result plot contains the plotted graph of the function and in the first line all parameter values to reproduce it. Also, the entire plot is copied to the clipboard.

Set the discontinuous Parameter to default, so write _
Now specifie the precision Parameter to true, so write 1, true or True
Also specifie the ascii_only Parameter to true, so write 1, true or True

Note: Use 0, false or False to set a Parameter of type bool to false.

py main.py f(x)=sin(x) 0.2,10 5,14 81,32 _ _ 1

Now the plot contains only real ASCII characters and the character of each point depends on its slope.
