Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • Lookng for example Using Google Charts with Alpha v11

    Hi group!

    I am looking to use the Google Charts API to generate some charts in my Alpha application. They have a prettier look to them than the built in charting API (sorry, please don't take offense). I found a really great how to example video but it is using v12 UX component but we only have v11.

    http://alphasoftware.net/alpha-anywh...hart-controls/

    I also created a real simple example using a static data chart just via copying and pasting code from Google Charts into a A5W page from:
    https://google-developers.appspot.co...cs/quick_start
    but obviously I need to do something more advanced as I wouldn't code everything in my A5W page.

    I searched Message Board and see comments from others about using Google Charts from v8 on up but I can't find any example on what I need to do. I have copied down the Google Charts API to my JavaScript folder within my Web Project. I'm thinking I need to start with a Dialog component but I'm still a newbie and afraid to waste my time and head down the wrong path as I am under a tight deadline.

    If anyone could offer some advice or provide an example, I would be forever grateful! Thanks!

    Re: Lookng for example Using Google Charts with Alpha v11

    Update. Here's what I've tried and I'm getting an error: "Object doesn't support property or method 'arrayToDataTable'

    1) I started with a Dialog Component

    2) Added Static Text control and in the SOURCE property added the following HTML:
    <!-- per example at https://google-developers.appspot.co...ery/combochart -->
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">
    google.load("visualization", "1", {packages:["corechart"]});
    </script>

    <div id="mychart" style="HEIGHT: 3in; WIDTH: 3in"></div>

    3) Created a JavaScript function:
    function drawChart() {
    // Some raw data (not necessarily accurate)
    var data = google.visualization.arrayToDataTable([
    ['Month', 'Bolivia', 'Ecuador', 'Madagascar', 'Papua New Guinea', 'Rwanda', 'Average'],
    ['2004/05', 165, 938, 522, 998, 450, 614.6],
    ['2005/06', 135, 1120, 599, 1268, 288, 682],
    ['2006/07', 157, 1167, 587, 807, 397, 623],
    ['2007/08', 139, 1110, 615, 968, 215, 609.4],
    ['2008/09', 136, 691, 629, 1026, 366, 569.6]
    ]);
    var options = {
    title : 'Monthly Coffee Production by Country',
    vAxis: {title: "Cups"},
    hAxis: {title: "Month"},
    seriesType: "bars",
    series: {5: {type: "line"}}
    };
    var chart = new google.visualization.ComboChart(document.getElementById('mychart'));
    chart.draw(data, options);
    };

    4) Added a button and OnButtonClick event call drawChart();

    5) I also added javascript/gviz-api.js to the Dialog, Properties. This is the API downloaded from Google Charts.

    here is a jsfiddle demonstrating the code working: http://jsfiddle.net/mn3ayp6b/

    It's as if something in the Alpha environment isn't recognizing the Google API but I've tried everything I can think of to no avail. Any help would be greatly appreciated.

      Figured it out.....In the Dialog Properties I needed to reference the Google API in the JavaScript - Linked files as follows:
      https://www.google.com/jsapi

        Selwyn has made a video, goes through all of that. It is worth watching.

          Thanks Michael. I did watch it (mentioned in my first post) but it's using a UX component in v12 and we only have v11 which doesn't have UX components so I wasn't sure where to start. however, it did give me the information I needed and through much trial and error, I got it going.

            The dialog is a UX. They work in both.

              Hi Stephanie,
              So far my experience with Alpha + Google charts has been very good.
              Better to use SQL as backend for good performance.
              The only issue that I have come across is that if you include chart configuration options for the user, sometimes the chart refresh following the Ajax callback does not work well - but it might be that Im missing something.
