Hi Timothy,

No, you can’t add two (or more) quantitative variables (attributes) to an axis to create parallel dot plots. Sorry.

As you probably have already discovered, if your two (or more) distributions belong to a single attribute and can be distinguished by a categorical attribute, then it’s easy to get the desired parallel dot plots. I’ve enclosed a screenshot of this.

Hi Stephanie,

It sounds possible but tricky. How would you match up the sites? Perhaps you could make a shared view of the CODAP document so others could take a look?

Hello Michael,Thanks for sending the file.

The problem is with the hash mark (#) in the first row. CODAP interprets that as an indicator that there is metadata in that row and does not include it in the dataset proper. By changing the hash mark to a column name, like N the file imports as one would expect. To illustrate what I mean by metadata, here are the first 14 lines of the exported data from the Mammals sample document in which you can see the hash marks and metadata for each attribute.

# attribute — name: Mammal, description: The species of the mammal, editable: true

# attribute — name: Order, description: The order of the mammal, editable: true

# attribute — name: LifeSpan, type: numeric, unit: years, editable: true

# attribute — name: Height, description: The average height of the mammal., unit: meters, editable: true

# attribute — name: Mass, description: The mass of the mammal, type: numeric, unit: kg, editable: true

# attribute — name: Sleep, description: The number of hours the animal sleeps in a 24 hour period, type: numeric, unit: hours, editable: true

# attribute — name: Speed, description: The average speed of the mammal., unit: km/h, editable: true

# attribute — name: Habitat, editable: true

# attribute — name: Diet, editable: true

Mammal,Order,LifeSpan,Height,Mass,Sleep,Speed,Habitat,Diet

African Elephant,Proboscidae,70,4,6400,3,40,land,plants

Asian Elephant,Proboscidae,70,3,5000,4,40,land,plants

Big Brown Bat,Chiroptera,19,0.1,0.02,20,40,land,meat

Thanks for reaching out with this question!

Hello Michael,It would help if you would provide the csv file. I suspect there is something unusual about it.Thanks,Bill

[Bill Finzer]

Hello,I’ve enclosed a screenshot of a binned dot plot in which the data are grouped by intervals and the Count option is enabled so you can see how many cases are in each interval.Does that help?

Bill

[Bill Finzer]

There is no way to change the default number of cases to be imported. It is hard coded as 5000. But, as you know, if the number of lines in a ‘csv’ file is greater than 5000, when the dialog box you can change the number of cases to import to anything you like, including 500.If I may ask, what is the reason you would like to change it?

[Bill Finzer]

Hello,There is information about functions in the formula editor. I’ve enclosed a screenshot of the info for isBoundary.

Hello,The Choosy builtin plugin may be of help. Notice that in the screenshot using the Tag Cases tab you can create an attribute and assign values based on selection.Does that get at least partway to solving your problem?Bill

Hello Marcos,Welcome to the CODAP Help Forum. In addition to Bridget’s recommendations, I suggest searching for CODAP on YouTube. There you’ll find a CODAP play list, an ESTEEM playlist featuring CODAP and quite a few additional interesting videos.And I second Bridget’s request for more information on what your plans for using CODAP are at this point.Best,Bill

Hi Travis,Unfortunately, no, there isn’t.Bill

[Bill Finzer]

The configuration option (the one that looks like a histogram or bar graph) appears on dot plots and dot charts, but not on scatterplots (because no configuration applies there).

[Bill Finzer]

Yes. It should be out by end of this week (6/14). Current build number is 0725, so when that becomes greater, it will be a new release.

[Bill Finzer]

Hello Travis,Thanks for letting us know of this problem. I’ve determined its cause and it should be fixed in the next CODAP release.Bill

[Bill Finzer]

Thanks for letting us know!

[Bill Finzer]

Hello,We haven’t seen this problem before. Would you mind enclosing a shared link to the CODAP document so we can check it out?When you plot attributes that don’t have such large values does the graph show measures as normal?If it turns out that it has to do with the very large values, you could create a new attribute with a formula that divides **Total World** by one billion. You could give this new attribute units, such as $B.
