Oh boy…

just add other values to x and y

You need to understand the Code

how  
this is my code

```auto
void setup(){
  
size(300,300);

for(int i=0; i<300;i=i+30){ellipse(i,i,15,15);
}}

```

Wow

Please look at my first post again what to do with x and y

Show your code, how can we spot errors otherwise

Understand the idea:

The for loop tells how many ellipses we generate - using variable i

The x and y variable tell the position. You can give them an start value 0 or 35 and then inside the for loop add something to x and to y. Eg 30 for x and 30 for y.

When we add something to them in the for loop x and y store the new value and get bigger each time. So the next Ellipse is further down.

You can also add different values to x and y

Still not success

What is the difference between (for and while)

I used noise() to generate those ellipses:

```auto
float xoff = 0.0;

for (float th = -TAU/20 +TAU/2; th < 3*TAU/2 + TAU/20; th += TAU/500)
  {
  xoff = xoff + .02;
  stroke(0);  
  strokeWeight(4);
  float r = 40 + 10*noise(xoff);
  point( r*cos(th)+50, r*sin(th)+50);
  println(noise(xoff));
  }

```

I could do similar for lines and text to achieve the effect you are looking for,

Post your code and then we can have a look

For and while are similar, see reference

Here the initial x value is 35 or something (like before) but the initial y value is height-35 or something (height is an inbuilt variable telling you the height of your sketch window).

Read the tutorials to understand the x and y values on the screen as I said please.

Now in the for loop you have to add something to x.

But since y is already pretty high, you have to **subtract** something from y to get the position of the next ellipse.

You forgot to show your code

Did you read the tutorials?

Did you read the reference for the for loop?

No.

It’s your code.

You fix it.

Nobody will do it for you.

Post your entire code.

insofar i would like to ask what the TITLE should mean?

> Inversely ellipses

in my example code  
the axis and “row” of circles might fit better to the  
very first picture you show us.

I want number bottom to top  
And ellipses also proportional

How to write numbers bottom y to top y  
And bottom ox to x  
And ellipses bottom y, x to top like proportional
