How do I use the Chart control in App Lab? I have been telling my students to take a snapshot, save it as a jpeg and then upload it and view it as an image - but can the data be used by the chart tool “live”? That would be much better. In any case, I can’t see how to use the Chart control in app lab, please let me know - or point me to the appropriate documentation, I can’t find any. Thanks.
@jpnelson Once you upload an image of the chart, the data will not be accessible. There is a data tab in App lab where you can import the data from the columns and rows. See the App Lab documentation here and look at the functions available in the Data tab.
The documentation links you sent seem to show how you can build charts off your own JSON data, or from csv data, but how do I read from the code.org data sets? I don’t see anything in this documentation on that.
How do I read from the code.org data sets? - Its integrated in App Lab. See Unit 5 which covers data.
I know well how to use the data sets - but how do I get the data from the data set into the chart control? I used to be an RDBMS programmer - is there an equivalent to “Select * from DOGS where Maximum_Lifespan > 10;”? I don’t see in the documentation how to do that, can you point me to the right place? Thanks!
