Coupled with a drawing grid and data sets, all you need to make AP Grid work are numbers. Overall, it is a great tool that combines art, math, and engineering. Now, that is STEAM!

The Artplotty Grid Art Board

The art board contains the x-axis, y-axis, the grid, and the art layer.

Within the art board, is the grid, x-axis, and y-axis. For the size of the grid itself, it spans 600 pixels in both directions.

The Data Sets

Line and circle datasets.
AP Grid datasets.

Using the line and circle datasets, you can cover a large amount of the grid. The main reason behind that is, you get to use decimal numbers for your key values.

Thus, you can have a values like 2.111 and 19.999. Just keep in mind that, the minimum value for both x and y is 0. And, their max value is 20. Although the grid is 600 pixels in size in both directions, we use small numbers to make it easier to plot points.

Using Artplotty Grid

Creating Lines

A line from point (2, 5) to point (18, 14).
A line from point (2, 5) to point (18, 14).

To create a line, you need two or more points. Altogether, the line data set holds up to 400 points.

With that in mind, follow the steps below to create a line from point (2, 5) to point (18, 14).

  1. Firstly, click New from the menu
  2. Under the line data set, type 2 for x and 5 for y
  3. After that, right under (2, 5), type 18 for x and 14 for y

There you have it! A line from (2, 5) to (18, 14).

Note: You can also input decimal numbers, such as 2.403 and 9.999 also works.

Continuing the Line

If you want, you can continue from the previous point to a new point, which will keep the line going. In the above example, we add two more points, forming a triangle.

Creating Circles

Likewise, creating a circle requires data. Therefore, the main data you need is the circle’s center point (x, y) and its radius (r). Of course, we have those options ready for you within the circle data set.

So, let’s create a circle at center point (10, 3.5), with a radius of 2.

  1. Click New from the main menu
  2. Under the circle data set, type 10 for x and 3.5 for y
  3. For the radius, type 2 for r

As you see, you need all three values to make a circle. Moreover, you can also enter decimals, like 19.999 and 5.374 for x, y, and r.

In case you did not see, the Start and End values are automatically populated, with 0 and 360. You can change these if you understand angles. For now, just understand, a full circle generally starts at 0 and ends at 360.

The Redraw Option

Occasionally, you may need to make a change or correction to your data. In that case, you will need to redraw your points. Click Redraw from the menu to update your art.

Note: Reloading the page will also update your artwork.

Downloading Your Artwork

At the moment, the download option only works on certain browsers. For instance, you can download your art without a problem in Google Chrome and Mozilla FireFox. On the other hand, that option does not work in Internet Explorer nor Safari.

Saving Your Work

Unfortunately, we do not have an option to save your work, which would include mainly the data. However, we are also planning various options to save just the data. Furthermore, we plan to create an option that will allow you to export your art in SVG format.

Creating Arcs

Arcs are angles that do not go all the way around. Basically, you create an arc by specifying a start point and an end point. In AP Grid, the starting and ending points are in degrees. Typically, a full circle goes from 0 degrees to 360 degrees. That is one rotation, which is all you need. However, you can input degrees beyond 360.

How It Works

All you need to do is, input the start and end angle. In addition, you have to be mindful of the fact that the angles go in a clockwise direction.
