Click Events for (most types of) Bar Charts

[whtt-eric]

Hi,

First of all, I want to say that I LOVE this chart library. Combined with this Rails plugin, I was able to quickly and easily produce some really nice looking charts for a RoR project I'm doing for the company I work for, Assembla.com (shameless plug).

The only thing that was missing was clickable bar elements. Since our client needed to have clickable elements in their charts, one of my team and I went in and made some adjustments to the various types of bar charts to allow for click events.

Charts that support the "on-click" property are:

• Bar
• Horizontal Bar
• 3D Bar
• Glass Bar
• Outline Bar
• Sketch Bar

Attached is a zip file containing the modified source files.

I hope this helps some people out.

monk.e.boy, if you end up using this code in a future release, and you include a list of contributors somewhere, I would appreciate it if you could include our information:

Eric Salczynski (Assembla, LLC - eric@wehaventthetime.com)
Duc Duong (Assembla, LLC - duc.assembla@gmail.com)


Thanks,
Eric

If possible, please include on-click support for stacked bar charts, too.

hi there,

first of all, thanks for the great library and for this piece of code. it's exactly what I was looking for!

i got a bit confused: there's only .as code in the zip. what about the methods to set the click events on the library? (ex: $bar->set_click())

if you could give a little example on that i'd be very grateful

thanks,

Filipe

Yes you will probably have to add the method to support the new functionality to the PHP library. I was using a Ruby on Rails plugin that needed to be modified as well.

I looked at the "php-ofc-library" and I think all you need to do is to add this method to the bar_base class in ofc_bar_base.php

/* put me in ofc_bar_base.php */
function on_click( $event )
{
$tmp = 'on-click';
$this->$tmp = $event;
}


Let me know if that works for you.


Also, I don't think this patch has been applied to the download yet, so if you haven't already, you will have to apply the patch and re-compile the Flex code.

Each "value" needs to be an object with a "top" and an "on-click":

Code: Select all

  {"type":"bar_glass", ...
   "values":[ {"top":7, "on-click":"http://www.google.com"}, ... ] },

I meant to do this earlier, but never got around to it. Sorry, guys.

Here's a zip file containing the re-compiled open-flash-chart.swf with support for bar on-click events. There are some examples of usage in there as well.

Unfortunately, my compiled output was about twice as big as the original. I compiled it using the free Flex SDK with mxmlc from the command line. If anyone has any tips on how to shrink the output, I would appreciate the input.

Nice work Eric, it worked perfectly. A rails example for Bar chart click events can be found here.
