CODAP can work on a tablet/mobile device but since it is a work in progress, not all functionality is yet available in the tablet format. Two notes:

• Dragging on an iPad: tap and hold for a bit longer than you might expect before dragging.
• In general, phone screens are too small to use CODAP effectively.

You don’t need to log in to use CODAP. However, if you want to save your CODAP documents on Google Drive, you will need to create a Google account and connect your Google account to CODAP.

Yes, CODAP has an API. For more information, see this FAQ on “How do I make a plugin or game with CODAP?”

One way to collaborate on a CODAP document is to save it in Google Drive and change the permissions in Google Drive (as you would for a Google Doc) to give edit access to the people/accounts who will also be working on the document. Unlike Google Docs, however, only ONE person/account at a time can edit the CODAP document (otherwise some of the edits will not be saved). Be sure to have only one person/account at a time editing the CODAP document, with the document not open anywhere else. A best practice for collaborating is to “pass the baton.” For example, if you finish the edits you want to make, close the document and tell your collaborator it is now their turn to edit.

You could also collaborate by creating a shared view link and then have a collaborator open the link, make edits, and create a new shared view link to the version they edited. Version control can be trickier with this method as you will end up with multiple shared view links (and multiple saved CODAP documents if you save the documents in addition to creating shared links). For this shared view link collaboration method, a best practice is to rename each new version of the document, adding something like v1, v2, etc. or the date to each new version.

If you would like to provide instructions to others on how to use a CODAP document you have prepared, you can take advantage of the Guide panel, which can be found by clickin on the “Options” gear icon in the top toolbar. Creating a Guide allows you to create instructions within the platform. The Guide you create will need a website and links to those pages. Another option is to provide instructions in your CODAP file in a Text box.

If you have a numeric attribute or a date/time attribute and color points on a graph or color points or boundaries on a map by that attribute’s values, CODAP divides the data into five quintile bins, with each bin holding 1/5th of the cases and corresponding to one of the five colored bands on the graph or map’s legend. The leftmost color band/bin on the legend represents the first quintile (the 1/5th of cases with the lowest values, or the earliest date range), ascending to the right until reaching the fifth quintile (the 1/5th of cases with the highest values, or the most recent date range). The numeric or date ranges for each quintile bin/color band are inclusive (not exclusive), so a data point or map boundary can belong to two quintiles if its value falls exactly on the dividing line between the two quintiles (note, though, that CODAP will color the point with just one color, but if you click on either of the adjacent quintile color bands in the legend to select the corresponding points, you will see the point/boundary highlighted for both quintiles). It is also possible for one specific numeric or date/time value to be in more than two quintiles/color bands on the legend. For example, in a dataset where the vast majority of values for an attribute are 0, the first four quintiles may all represent a “range” of 0 to 0.

In order to save CODAP documents to a Google Drive account or to open CODAP documents saved in Google Drive, you must first enable permissions for CODAP to connect to your Google Drive account. When you first try to save a CODAP document to Google Drive, you will not only need to log in to your Google account, but also enable permissions in the box that appears (see screenshot below). In order for CODAP to integrate properly with Google Drive, check all the boxes and click “Continue.”

For guidance on how to integrate a NetLogo simulation model into CODAP, please refer to the CODAP NetLogo Integration Guide.

First, check out the CODAP plugins database to see lots of examples of CODAP plugins. If you do not see a plugin that fits your needs, you can create one yourself! Dive into our Github repository to learn more about CODAP plugins. There is also this tutorial and this detailed description of the CODAP API that can guide you in making a CODAP plugin.

There are two ways to save a CODAP Document. But note that you might get what you want by sharing your CODAP document; see this page to learn about sharing.

Save a CODAP Document on Google Drive

To save your documents on Google Drive, you will need a Google account.

• For more information on using Google Drive with CODAP, visit this page.

Once you’ve connected your Google account and saved to Google Drive, any further updates to the CODAP file will be saved automatically to Google Drive.

Saving a CODAP Document Locally

To save a CODAP Document to your local hard drive, click on the File icon from the menu and click on “Save.”

Select “Local File,” then click “Download.”

The document can be found in your download folder as a .codap document.

• For more information on saving a CODAP file to your local hard drive, visit this page.

A plugin is a piece of software that acts as an add-on in CODAP. It gives a CODAP document additional functionality. For basic information on how to use plugins in CODAP, visit this help page.

You can drag a URL of a dataset over the workspace, or import it through the Import Menu, but sometimes this will fail with a mysterious “Network Error.” Here are some things to check:

• Is there a problem with your network? Check your computer or device’s network settings. Perhaps you have become disconnected from your wireless network or the network is overburdened.
• Is there a problem with the URL? If in doubt, you can try opening the link in another browser tab. If the URL is for a CSV file, the file may be downloaded to your computer, then uploaded/imported into CODAP.
• Some websites are not configured to permit web applications from fetching data files, but do permit users to download the files. If you are able to download the file, please do so, and then drag the file into the CODAP workspace to add it to your CODAP document. See here for more info on how to upload files into CODAP.

To run CODAP, you will need: (1) a computer with Internet connection and (2) a relatively recent web browser. That’s it!

CODAP has primarily been developed/tested in Chrome, but it should work in any modern browser updated within the past few years, such as Chrome, Firefox, or Safari. If you encounter a bug related to your browser, please let us know by posting in the help forum.

The Common Online Data Analysis Platform (CODAP) is a data analysis platform and community of developers where you can easily work with data, simulations, and games—and share your insights with others worldwide.
