See the change log here.
Developed by InformaticFreak (c) 2021
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,cotasin,acos,atan,acotdegrees,radianlog,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.
f(x)=sin(x) 0.2,10.0 5,15 81,32 0 0 0

- Set the
discontinuousParameter to default, so write_ - Now specifie the
precisionParameter to true, so write1,trueorTrue - Also specifie the
ascii_onlyParameter to true, so write1,trueorTrue
Note: Use
0,falseorFalseto 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.
f(x)=sin(x) 0.2,10.0 5,15 81,32 0 1 1
