Google Chart Annotated Timeline Flash Legacy Tutorial

With major players in the Information Technology space there are bound to be clashes regarding supported platforms. One ongoing dispute involves support for Adobe‘s Flash (Player) with Apple mobile devices (using the iOS operating system).

When such concerns arise, developers often look for solutions that do not rub up against limitations such as this, rather than waiting for the dispute to finish, as that can take a long time.

Some Google Charts code goes back to times before this issue and as such, some of the charts were designed with Flash usage in mind. One of these is the Annotated Timeline Chart which we last talked about with Google Chart Annotated Timeline Select Event Tutorial as shown below.

So today we “bite the bullet” and make the Flash version (usage) of this chart become non-default, and use the Google Chart Annotation Chart as the underlying default methodology for our Annotated Timeline web application.

Yesterday’s Google Chart Gantt Chart Primer Tutorial was the start of our voyage of discovery into Google Charts Gantt Chart here at this blog. Looking at this Gantt Chart reminded us of another chart that doesn’t form the dependencies of the Gantt Chart but does offer a good way to display the Gantt Chart data in such a way that information is all there in a good display mode, and that chart is the Google Chart Annotated Timeline Chart we first talked about with PHP/Javascript/HTML Google Chart Annotated Timeline Chart Tutorial.

Well, today, it seems like a good time to introduce some ‘select’ event functionality to the Annotated Timeline Chart, so that it is ready to have some synergies with the Gantt Chart, to end up with relationships among …

  • Calendar Chart
  • Timeline Chart
  • Annotated Timeline Chart
  • Gantt Chart

… which is not particularly surprising, as they all relate to the “when” of life, and if that’s how you tend to think as well, they can be a useful way to express your linking of “when” concepts with “why” and “how” and “where” concepts, perhaps … or some other types of concepts. “Who” knows? But I ask you, or perhaps Abbott and Costello first asked, “Who told Who?”.

Yesterday we said …

What can a Gantt Chart help with? Not looking anything up here (but you might) we think the Gantt Chart is great for setting deadlines and to turn up with in meetings focussed on outcomes (more so than incomes … chortle, chortle).

  1. establish date ranges for when tasks (or activities) should start and when they should complete
  2. allow for estimates of task “percentage achieved”
  3. define dependencies, as in, “does this task depend on the completion (or some other criteria) of another task”

… and today we use the Duration and Percent Finished data points as the numerical datapoints the Annotated Timeline Chart asks for.

Seems a fair time back we were discussing the ‘select’ event in relation to Google Charts functionality, but probably it isn’t. And perhaps it was a fair while back, but maybe it wasn’t, that Google and its Charts team introduced a new chart called the Gantt Chart, which a lot of people out there will know well, or less well, as a Project Management tool.

We hook into the PHP server language strength of allowing the POST method processing of HTML form data, to get around the URL “GET” (method) length restriction all web servers have, usually at about 2000 characters (we recommend the following background reading regarding this) … though with our web server it seems to be a smaller limit … anyway.

It probably comes as no surprise that chart data can be turned into spreadsheet data, especially if you have ever spent much time in those great spreadsheet applications like Microsoft Office’s Excel, where there are various pathways to display charts from your spreadsheet data. So, today, we just turn that thought around a bit, and use Comma Separated Value (CSV) files as a conduit to be able to convert our chart data into a spreadsheet. We leave it up to whatever is the default application you have to open CSV files … it doesn’t even have to be a spreadsheet application as such, but our applications today offer a downloading capability to get the spreadsheet (CSV) data down to your hard disk (or perhaps midair solutions like Google Docs).

So we see this as a good candidate as a generic Google Chart “select” event tool for users looking to integrate with spreadsheet tools.

This piece of functionality can be useful, even in terms of aesthetics, as some Google Charts display better than others depending on the density of the data set(s) displayed.

Along the way we also present to the user a moving average of values relevant to each data column of interest.

From yesterday, you may also recall that we can allow a redraw of one the Google Chart types as above (and for lots of others eventually) by allowing user amendment of the data.

And from the day before yesterday we outlined that first bit of “select” event business logic allowing the user to see the difference between values, on “click/touching” any one of them and on doing this firing the “select” event.

Google Chart Line and Map Chart Select Event Prompt Tutorial

Google Chart Line and Map Chart Select Event Prompt Tutorial

Here is a tutorial that further reacquaints you, maybe, with the Google Graphs API, or Google Chart Tools, and its Line Chart functionality, last talked about at this blog with PHP/Javascript/HTML Google Chart Line Chart Tutorial as shown way below, and Map Chart, for its first mention and Google Chart Map Chart Select Event Primer Tutorial, for its last mention.

There is no magic relationship between these two chart types today, rather it is the case that they are the “guinea pigs” for “generic thoughts”.

“Generic” is a favourite word for what we try to achieve here, but it can be like “nirvana” for lots of reasons …

  • do you have a market for the investment you need to put in to push for “genericity”
  • in similar mind, does the project size make it worthwhile
  • is catering for all the web browser and application platforms allow for “genericity” anyway?

… in a big organization, such queries can progress quite nicely by using teams and having planning discussions and setting timelines and deadlines between project groups, but in smaller teams it can be the case of “seeing what problems” come up, to decide on the push for “genericity” with the product, down, eventually, to the level of deciding where “business logic” code should sit (ie. in a “library” or “called” piece of code, or otherwise). So, we’re trying some “generic” thoughts and using these two disparate Google Charts to see whether there is some onclick (ie. Google Charts “select” event, which you can read a lot about here … thanks, Google) logic that, in a business sense (because we like to think of onclick being really closely tied to “business logic”, the reason being, some user “clicked/touched” something, so you better present something heading towards specific interest, to do with business, when they do this.

And we think an approach would be to offer an onclick reworking of the data of a chart should they get to the “click/touch” stage with a chart. And we decided that it is not so bad to present this in an overall “one string” chance to change the chart, because, presumanly the user went through the whole rigmarole of answering questions to get this far, and by this stage will “get the hang” of what to do to make more sweeping changes by using this new functionality. Think, too, a “faster way to do things” presented to “advanced users” willing to give things a go (otherwise they wouldn’t still be reading?!) help to improve the UX (“user experience”) of the application, whether that be web or mobile or desktop or seascape (just checking you’re still awake).

And so, in practical terms, with these two charts, we’ve recently added onclick (Google Charts “select” event) Javascript alert and prompt boxes recently, respectively, for Line Charts and Map Charts. Well, today, we make them both Javascript prompt windows to offer this chance for the user to “reshape” their chart via “click/touch” chart control.

This extra functionality, available via the suffix β€œ&onclick=y” applied to the Google Chart Map Chart title, flows on directly to the iPad iOS App we created and talked about, last, with Xcode Swift iOS Application End Game Primer Tutorial.

PHP/Javascript Google Chart Line Chart Select Event Tutorial

Here is a tutorial that reacquaints you, perhaps, with the Google Graphs API, or Google Chart Tools, and its Line Chart functionality, first talked about at this blog with PHP/Javascript/HTML Google Chart Line Chart Tutorial as shown below.

Google Chart Tools provide a perfect way to visualize data on your website. From simple line charts to complex hierarchical tree maps, the chart galley provides a large number of well-designed chart types. Populating your data is easy using the provided client- and server-side tools.

The reason for the revisit concerns a push to make more use of the onclick “feeling” Google Chart “select” event, an event triggered when you click on a feature of, in this case, a Google Chart Line Chart that our web application helps you create.

Here is some PHP code in live action for this tutorial where you define your line chart characteristics and data, where am appending of “&onclick=y” to your line chart title means the additional “select” event functionality can kick in.

The “select” event functionality (which you can read a lot about here … thanks, Google) would be full of business logic and specific to how you want to use the chart, so it is a bit hard to pin down how you should use it, but in today’s tutorial picture you can see that in a Company Performance line chart showing Sales and Expenses if you click on a Sales figure for any given Year the “select” event business logic brings up a Javascript alert() box that informs the user of the Expenses for that same Year, along with the difference between Sales and Expenses. The logic is not tied down to the exact words “Sales” and “Expenses”, and it will work this out from what you entered in for this earlier on.

Some findings here led to some small changes to that generic Javascript behind the scenes of these Google Chart suite of web applications as well so, all told, the changes involved …
