Artplotty Grid 21 – Online STEAM tool

Artplotty Grid 21 (or AP Grid 21 or APG 21) is an online tool that allows you to create designs with numbers. STEAM is short for science, technology, engineering, art, and math.


All you need to use APG 21 is an Internet connection. Preferably, Google Chrome or Microsoft Edge.

Quick glance of Artplotty.

Artplotty contains a main menu, a grid, two datasets, and an upload data area.

  • Main menu – Create a new grid, save your work, redraw points, hide or show the grid, and download your art.
  • The grid – A 21 by 21 plotting area, for you to create your design.
  • Two datasets – A line dataset and a circle dataset.
  • Upload – Use the upload data area to load a design you previously saved.

Overview of APG 21

The way APG 21 works is, you create designs by plotting points with the line and circle datasets. It is just that simple.

Below is a list of people in certain industries who will benefit from using APG 21.

  • Teachers
  • Students
  • Artists
  • Engineers
  • Architects
  • Hobbyists

Artplotty is a great mind exercising tool. Of course, you can do basic to advance stuff with it. However, not everyone will use it in the same way. In any case, it is up to you.

As you see, Artplotty is fairly simple to use. In this video, we create the impossible box and download the art as a transparent PNG.

Using Artplotty Grid 21

Using APG 21 - The grid.

The grid

When using APG 21, you are working on a 21 by 21 grid. So, that is from 0 to 20, including 0.

Although that may seem like a small grid, trust us, it is bigger than you think. In fact, the grid increments by .5, allowing you to really fine tune your designs.

Moreover, depending on the way you enter your data, you can go off the grid. Hopefully, we will get to show you that technique here.

The datasets

In version 3.1, we include 2 datasets. One for lines, and one for circles.

The line dataset contains 400 rows. And, the circle dataset contains 50 rows. In the future, we may expand both datasets.

Both datasets contain a scrollbar, allowing you to maintain view of your work, while you create something great.

Entering data

So, when you enter data, you have the option of using whole numbers, or numbers with decimals.

At this time, we only allow up to 6 places, including the decimal point. This means, you can have numbers like, 12.431, 6.5, 2.0219, and even 3.1415.

Notice, with the six places rule, you have to take into account a few things…

A number that is above 10 will allow you 3 digits after the decimal. However, numbers below 10 will allow 4.

Believe it or not, it is possible for one of you to need 4 places after the decimal. Therefore, we will consider this in our next upgrade.

Creating a basic line

So, to create a line, enter the starting point and the end point. In this case, use the line dataset. First, enter (2, 5) as your first point. Lastly, enter (18, 14) as your end point. Now, you just created a basic line. You are off to a great start.

Creating a triangle

A triangle takes three points. Just follow the same rules as you did for a line. As you noticed though, in APG 21, you end where you start. Therefore, you will have four points to plot. Unless, you take a different path.

Drawing multiple objects on one grid

If you want to draw multiple objects on one grid, then all you have to do is skip a row in the line dataset. With the circle dataset, there is no need to skip a row.

Creating a circle

To create a circle, you need two components. First, you need a center point, which is a x, y coordinate. Second, you need a radius. You plot all three in the circle dataset. In our case, we have a center point at (10, 3.5), and a radius of 2.

Keep in mind, after you enter your x, y point, the Start and End values are automatically populated. The Start and End points are for creating arcs. So, if you want to create an arc, you will have to change those two values.

Remember, after you change a value you have to Redraw to see the results.


The Redraw function is a very important feature of Artplotty. If you make a change in either dataset, then you should Redraw the canvas. You can see this in action in the above video.

Creating an open arc

If you want to create an open arc, then all you have to do is adjust the Start and End values in the circle dataset. In the above figure, you can see the Start and End values within the circle dataset.

So, the start and end values are a whole numbers, from 0 to 360. These two values are represented as degrees. Also, when plotting arcs in APG 21, the angle rotates clockwise.

Moreover, you can go past 360, up to 999. That will just make the circle thicker.
