Creating charts in MIT App Inventor

App Inventor for iOS
1

Hi guys,

I am just wondering if anyone is able to help me.

I have created a wellbeing application which allows users to log and track their mood, sleep, nutrition and reflection . I am trying to create an "Insights" page which gets the date that they have entered from the database and displays their information over a period of time using graphs but I do not know how to do this.

I have also tried to import the Chart Maker extension but this is the error message I am getting.

You could also give the native AI2 Charts component a try:

I have downloaded this extension! It won't open for me.

You cannot OPEN it, you need to download aix to your computer; then drag the aix into your Project.

Oh great, thanks that worked. How can I link the charts to a database? Im using myPHPadmin to save the users information that they have logged. How can I display this information and link it to the charts?

Thanks!

Download the information from your server possibly using Web1.GetText. Transfer the info to a List in your app.

Follow the example in the GitHub downlink; example code is available if you scroll down.

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles

How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Are you using iOS companion ?

Yes

Extensions will not work with iOS.

Try the Charts component instead.
