Hello Elizabeth,
CODAP documents can be embedded as iFrames in other web pages where they remain fully interactive. I don’t have experience with Story Maps, but perhaps this will work there.
- From CODAP’s “hamburger” menu choose Share/Get link to shared view (as shown in the enclosed screenshot.).
- In the resulting dialog box choose Embed.
- Copy the embed code and paste it into the web page html.
- Adjust the dimensions to fit your content.
- You can, if you like, include the URL parameter ?embeddedMode=yes
to remove the CODAP tool shelf. (URL parameters are explained here.)
Please let us know if this works for you or if you have additional question.

Bill FinzerKeymasterAnswer: CODAP graphs can only bin one numerical axis. But you can create bins formulaically for a second numeric attribute as shown here. This document randomly generated values for Height and Weight and a slider named interval to control the bin width for a third attribute named Weight_binned. The formula for Weight_binned is
floor(Weight/interval)*interval+" to " +ceil(Weight/interval)*interval
The enclosed screenshot shows the result plot with both numeric attributes binned.

Bill FinzerKeymasterHi Travis,
I was able to create binned plots with the data you sent. Here is a short video.
Any idea what you’re doing differently?
Bill
Bill FinzerKeymasterHi Travis,
I just verified that binning works for me with 500 observations. Can you send a shared link to the document that is giving trouble?

Bill FinzerKeymasterHi Andee,
Definitely a bug! Thanks for reporting it.
Bill
Bill FinzerKeymasterI’m so glad you ask. This feature came about as kind of special for the Zoom In Science project. It works just as you describe for a LSRL in a scatterplot. We never got around to extending it to other measures and I’ve felt very guilty about that.
Now, with your prompting, I’ll move it up to the top of the list!
Bill
Bill FinzerKeymasterGood catch Andee!
Rick Hudson (of ESTEEM) beat you to the punch and, I’m happy to report, we have a fix in the works for the next release.
I’m glad you like the bins. They are brought to you by Victor Lee at Stanford.

Bill FinzerKeymasterHello Steen,
I apologize for somehow missing your initial post. The data game Shuffleboard relied on communication between the game and CODAP that is no longer in effect, but we didn’t realize that it was broken.
The game can be modified to work again. Meanwhile we’ll remove the game from the list at CODAP data interactives. Is that the site from which you were launching it? (There is another, older site that also lists it.)
Shuffleboard never supported save and restore because it was designed for quite short interactions. That, too, could be remedied.
Yours,
Bill Finzer
Bill FinzerKeymasterThanks for this bug report! I apologize for the delay in responding. The help forum software wrongly marked your post as spam.
Good news: the bug is fixed. The dates now display correctly in the case table.
Bill
Bill FinzerKeymasterThanks for the bug report! And I apologize for any delay in response. The help forum software is wrongly marking some posts as spam. 🙁
The good news is that this bug has been fixed. 🙂

Bill FinzerKeymasterThanks for this bug report! Working on it …
Bill FinzerKeymasterHello!
Thank you so much for this bug report. I apologize for what must be a delayed response as your post got marked as spam for some reason.
I’ve just entered your post into our bug tracking system and marked it as high priority to fix.

Bill FinzerKeymasterHello Robert,
Glad you appreciate CODAP’s design. We really try hard to make it simple to use.
The functionality you need is, unfortunately and with a couple exceptions, not present in CODAP.
- In a scatterplot you can plot a least squares regression line and r-squared is reported along with the equation of the line.
- There are a set of statistical functions shown in the enclosed screenshot. A good example of using the correlation function is described here.
CODAP is constantly evolving through collaborations with other funded projects, which have been mostly science education projects. No project has yet had the aim of developing materials that fully support introductory statistics with a full complement of tests and estimates.
Plugins, like the Sampler used in the (new) Duck Pond example document, provide a fairly straightforward way to extend CODAP’s capabilities. You, or someone you know with a modicum of programming chops, could create a CODAP plugin that would do the computations you desire within CODAP. Alternatively, consider writing a proposal to the NSF or some other funding agency, and we’ll collaborate!

Bill FinzerKeymasterHi Joachim,
Definitely not a silly question as being able to drag points is important in CODAP.
I’m confused. Your first paragraph implies that you are able to move a data point, right? If you have the mean and median displayed, you should be seeing them change while you are dragging the point. When you release the point it will slide back to its original place.
Your second paragraph implies that you are not able to drag a data point. Here are the conditions under which that would be true:
- The point’s position is defined solely be categorical values.
- The point’s values are computed from a formula.
If this remains unclear, perhaps you could share a document?

April 19, 2020 at 6:17 pm in reply to: Difference in graph when variable is numeric or categorical #1461Bill FinzerKeymasterHi Andee,
When the x-axis is numeric, the x-coordinate of the plotted point will be exactly its value above the axis. So if month is 4, the point will lie above the 4. If two points have the same value for month they may overlap if their y-values are close.
When the x-axis is categorical, each category gets a bit of space for its points and the points get stacked (horizontally in this case) as needed within that space. So two points with the same month and rainfall will be offset from each other horizontally.
I hope that explains the difference!
