Easy Charts with AppyBuilder

logo

Google Charts provides a variety of charts designed for data visualization. These charts are based on pure HTML5/SVG technology, so no plugins are required. All of them are interactive, and many are pannable and zoomable.  AppyBuilder includes a feature that allows you to add these charts to your mobile apps in a few simple steps.

Below is an app that was developed in AppyBuilder GOLD in matter of minutes!

AppyBuilder includes a WebViewer component. The WebViewer component includes a block called WebViewer.LoadHtml (see image above) that will allow you to load any type of html and set it to WebViewer. In above case, the html is set to THIS html, allowing for animated / interactive chart.

Using Multiple Database – TinyDB

logo

TinyDB is a Storage component that can be used to store data for an app; i.e it is a persistent data store for the app. The data stored in a TinyDB will be available each time the app is run. An example might be a game that saves the high score and retrieves it each time the game is played.

Data for TinyDB is stored using key (tag), value pairs. To store data, you specify the tag it should be stored under. Subsequently, you can retrieve the data that was stored under a given tag. The value for a tag can be a simple text or complex data structure like List of Lists.

Each app has its own data store. By default, there is only one data store per app. Even if you have multiple TinyDB components, they will use the same data store. Image below shows using 2 TinyDB but the underlying code is using the same data-store.

If your app has complex requirement and you require Multiple Independent data-stores, then AppyBuilder includes such feature / capability and will allow you break your data into multiple separate independent storage – see image below.

Image below shows how this can be accomplished. In this example, we have used 2 TinyDB, but notice that using block TinyDB.DatabaseName, we are assigning a unique name to our database. This name can be anything as long as it is unique and does not contain special characters or embedded spaces. For purpose of this tutorial, we are using same tag (platform) to store different values in each of the databases. When we retrieve data, you’ll notice that each database returns the correct value that it stored.

Webviewer File & Camera Upload Support

On desktops, HTML / php can be used to upload files from local device to a remote server. For mobile device, AppyBuilder includes Webviewer component for viewing web pages. For example, you can drag-n-drop this component into designer editor and set its HomeURL to webpage that you like to open:

The GOLD version, now includes support for uploading files from local mobile storage. It also includes support for taking pictures and directly uploading the file onto server! This feature can be very handy for such sites as Facebook  or for example allowing user to upload a local file or to take a picture and directly passing it remote server.

To use Webviewer, drag-N-drop this component onto design-editor and you’ll see a property named AllowCamera.

If you like to allow user to take pictures, checking AllowCamera property (set to true), will pop-up a Chooser window allowing user to take picture for upload. Let’s assume that you have a html like blow (source HERE):

From image above, you’ll see that the html page includes “Choose File” button for uploading file. Once clicked, this will pop-up the “File Chooser” window shown below:

At this time, user will be able to take picture and send to server OR can click on “Documents” to select a file from device local storage – see below:

After taking picture (or selecting a file) and submitting, our html can now perform actions on such as storing the image in server. In our case, the sample html (php) page only shows file-size information:

Image below shows the complete page flow:

DateUtils Extension

TextUtils extension will allow you to quickly perform such date functions as:

  • Formatting date / time, based on user requested formats
  • Obtaining date / time difference between 2 different dates. This will result in CSV text data that contains 4 elements. For example, receiving data 301,5,11,30 means the 2 dates have difference of 301 days, 5 hours, 11 minutes and 30 seconds.

For format, you can use the following patterns:

Format Pattern                         Result
 --------------                         -------
 "yyyy.MM.dd G 'at' hh:mm:ss z"    ->>  1996.07.10 AD at 15:08:56 PDT
 "EEE, MMM d, ''yy"                ->>  Wed, July 10, '96
 "h:mm a"                          ->>  12:08 PM
 "hh 'o''''clock' a, zzzz"         ->>  12 o'clock PM, Pacific Daylight Time
 "K:mm a, z"                       ->>  0:00 PM, PST
 "yyyyy.MMMMM.dd GGG hh:mm aaa"    ->>  1996.July.10 AD 12:08 PM

Shuffling / Ordering Lists

Lists are data structures that are used to create and/or manipulate different sets of values/elements.

In AppyBuilder / AI, Lists can be created by converting a CSV data into a List such as below:

Some apps, such as game apps (e.g. cards) require shuffling or randomizing a list. The shuffling would require coding (sometimes complicated) to make the shuffling happen. AppyBuilder has now developed an extension that can be used both in AppyBuilder OR MIT AI to perform shuffling using only one Shuffle block as shown below!

The extension also includes Sorting block for sorting a list in ASCeding (1) or DESCending (-1) order:

Wanna reverse a list? Then use Reverse block as shown below:
