BlotGrapher- V205

[V205Arduino]

Hi! This is my blot program.

This was a collaboration between me and @BrightTheBackpack

BlotGraph ( or BlotGrapher) can currently plot lines (probably can’t draw an equation with two y values for every x yet.) and crop them.

To draw lines, create a function for a formula in the format y = ???
Example:
var quadratic = function(n) { return (1 / 4 * n * n - 2 * n+ 4) } //v+Math.sqrt(r-Math.pow(n-v,2)))

Draw it in a draw turtle with the drawEquation command:
`drawTurtles([
drawEquation(quadratic, 1, 100, 20),

]);
`
The drawEquation function has these parameters:

drawEquation(formula, resolution, maxX, minX, maxY, minY)

All the parameters can be left blank except for the formula one

Old way(don’t use):

You can play around with resolution, maxX, minX, maxY, and minY.

The function used to draw lines is:
drawEquation(formula, resolution, maxX, minX, maxY, minY)
The formula will be something like this:

var quadratic = function(n) {
  return (1 / 4 * n * n - 2 * n+ 4)
} //v+Math.sqrt(r-Math.pow(n-v,2)))

And the rest of the parameters are non zero integers.
Resolution could be negative, but currently, I have blocked that.

Here is an example call of the drawEquation function.

// a quadratic.
drawEquation(quadratic, 0.1, 100, -100, 100, 0)

Or, if you don’t want to use all the parameters (only formula is required), it will just use default values.

// a quadratic.
drawEquation(quadratic)

There is more info in the code.

A display of all of BlotGrapher’s current features:
From left to right: A linear line, A sine wave, a quadratic, and another sine wave (but it is cropped).

Default program:

var linearLine = function(n) {
  return (2 * n + 2) //Math.sin(n) +
} //v+Math.sqrt(r-Math.pow(n-v,2)))
drawEquation(linearLine);

//draws a sine wave
// y = a * sin(n+ b) or something like that, I can't remeber
// y = sin(n) + 9
var sineWave = function(n) {
  return (Math.sin(n) + 9) //Math.sin(n) +
} //v+Math.sqrt(r-Math.pow(n-v,2)))
drawEquation(sineWave);

// another sine wave, but modified slightly.
// y = sin(n) + 21
var sineWave2 = function(n) {
  // similar to sineWave1, but adds 12.
  // it looks very different because of the additional parameters called(see below).
  return sineWave(n) + 12; // lazy way :) 

}
// here is a test of the maxX, minX, maxY, and minY parameters.
// the left, right, top and bottom are cut off.
drawEquation(sineWave2, 0.1, 39, 20, 21, 20.4)

// a quadratic equation
// y = ax^2 + bx + c
var quadratic = function(n) {
  return (1 / 4 * n * n - 2 * n - 2)
} //v+Math.sqrt(r-Math.pow(n-v,2)))

// a quadratic.
drawEquation(quadratic, 0.1, 100, 0, 18, 0)

Quadratic:

var quadratic = function(n) {
  return (1 / 4 * n * n - 2 * n+ 4)
} //v+Math.sqrt(r-Math.pow(n-v,2)))

// a quadratic.
drawEquation(quadratic, 0.1, 100, -100, 100, 0)

SineWave:

var sineWave = function(n) {
  return (Math.sin(n)+ 10)
} //v+Math.sqrt(r-Math.pow(n-v,2)))

// a sine wave.
drawEquation(sineWave, 0.1, 30, 10, 100, -100)

I’ll probably add more things later.

Is that enough?

Thank you.
I probably made a mistake in my formatting……

That image is completely drawn by BlotGrapher,
Most of the lines are quadratics in the form y = ?(x - ?)^2 + ?

(edit, adding photo)

@V205Arduino is attempting to deploy a commit to the Hack Club Team on Vercel.

A member of the Team first needs to authorize it.

Thanks so much for the submission. I love this graphing functionality! Do you think you could use it to make something artistic as well? I think this idea applied to creating a nice visual piece will certainly earn a Blot.

[V205Arduino]

Ok! I have created a visual piece

I will update the program now.

[V205Arduino]

I don't think I can reopen this?

[leomcelroy]

I think you're file is a little messed up. It's related to the {...} you have around comments. Could you clean that up so it runs properly? Also please center the PI in the drawing window.

[V205Arduino]

Ok, thank you,
I added the {…} to be able to collapse the code, seems like it does not work, fixing

[V205Arduino]

Is this eligible for a Blot or should I start over?
Thank you

[V205Arduino]

Have updated OP and code

[leomcelroy]

Nice! Here is your Blot order form. Well earned.

[V205Arduino]

Thank you!
