Graph

c-graph

`c-graph`

allows you to generate graphs of multiple expressions / points. The most commonly used (and fastest, hence the name) mode is `c-graph quick`

, which accepts a list of graph expressions to graph.Graph of y=x^2 and y=ln(x)

Graph of y=(x+2)^2+1 and y=-1/3x+2, showing graph interceptions and other points of interest

Graph of y>=x^2-4 and x=1

y=, x=, r=

If you do not include one of the above headers in your expression (

`y=`

, `x=`

, `r=`

), CalcBot will predict which header you intend and add it to your expression during rendering.CalcBot will accept relations; that is, expressions that aren't explicity in

`y=`

, `x=`

, or `r=`

form. Entering an expression like `3x+2y=15`

causes CalcBot to attempt to solve for `y`

to graph the expression as if it were in `y=`

form.Parametric equations

CalcBot can also graph most parametric equations. As long as two equations contain the variable

`t`

, either the variable `x`

or `y`

, and are placed right next to each other when typing them, CalcBot will recognize them as part of a parametric equation and graph it accordingly:Graph of x=t+1 and y=3t

Custom viewport

The viewport of a graph defines where the camera is positioned and how far to zoom in or out. CalcBot allows you to customize the viewport of

`c-graph`

to display the parts of the graph you want to see.By default,

`c-graph quick`

selects the viewport automatically. However, to customize the viewport for `c-graph quick`

, use the `c-graph quickviewport`

command, then describe the settings of your new viewport as follows:1. Select the properties from this list that you'd like to change:

`cam`

`x`

`y`

`xy`

`x`

and `y`

properties at once.2. Determine the new values of the properties that you will set

Each of the properties listed above accepts a certain value:

The

`cam`

property accepts a coordinate given in the form `(x, y)`

, which represents the position the viewport will be centered in.The

`x`

, `y`

, and `xy`

properties accept any number or expression (that can be evaluated with `c-calculate`

).3. Run the command

Type

`c-graph quickviewport`

, then for each property that you want to change, type the property's name, followed by a colon (`:`

), and then the value to set that property to, as described in step 2. You may optionally add a comma to separate any more properties to change. Here are examples of viewport settings and what they mean:1

c-graph quickviewport cam: (0, 0), x: 10, y: 10

2

Set viewport center to (0, 0); set x-axis scale to 10, and y-axis scale to 10

4

c-graph quickviewport x: 300, y: 20

5

Set x-axis scale to 300, and y-axis scale to 20

7

c-graph quickviewport cam: (pi, 0), x: 2pi

8

Set viewport center to (pi, 0); set x-axis scale to 2pi

Copied!

If your viewport was successfully parsed, CalcBot will send a success message, and you will immediately see the new viewport when running

`c-graph quick`
