This should be an easy one for someone... I expect it's obvious, but I've looked in various places on highcarts' site and google and simply couldn't find an answer...
From highcharts.com: (http://www.highcharts.com/articles/2-news/46-gauges-ranges-and-polar-charts-in-beta , http://www.highcharts.com/docs/export-module/setting-up-the-server)
To avoid bloating the Highcharts core JavaScript, we deploy the new chart types and features in a separate file called highcharts-more.js. We will continue to build extended functionality in this file, and reserve highcharts.js for common tasks and visualizations.
Basicly, they added some extra functionality on top of Highcharts without modifying it's core code.
Including this file, also allows you to use some types of charts which don't exist in the "original" highcharts such as bubble, range and pollar charts:
...Save highcharts.js or highstock.js for stock charts, highcharts-more.js (for bubble, range, polar charts)....

I recently customized the structure of filter exports to Excel following the instructions found at https://developer.atlassian.com/display/JIRADEV/Customising+JIRA+Excel+Output. This is great if you want to change the look and feel of the exported excel file.
However, how would I achieve conditional formatting based on status of exported issue set. For example, I would always like to see the "Closed" issues in Green color and "Ready to Test" items in Yellow. How do I achieve this?
Expected outcome
You could also use the Traffic Light add-on to create a custom field with the chosen color.

This is less distracting than coloring an entire row I find.
Use the Better Excel Plugin to export JIRA issues to custom Excel spreadsheets.
Important difference: these are real Excel files (XLSX format), unlike the HTML tables produced by the built-in Excel export feature.
You can use so-called tags to implement custom behaviour in the template. These are similar to HTML or JSP tags. In your case you should use the jt:style tag to specify the fill-background-color and fill-pattern properties, and wrap it in a jt:if condition.

I am using HighChart in my application.
I want to export chart image on a button click like http://jsfiddle.net/hfrntt/fXHB5/1896/.
but i want to save image in a predefined folder and remove the save dialog pop-up to save image.
On button click image saved on the predefined folder.(No save dialog)
Thanks in advance
You have to setup an exportserver. Upon the client sends the Highcharts SVG file to this service it will be converted to an image. Before the server returns the image to the client you can save it to the predefined filesystem.
Here you can find a php export server and a java based one. https://github.com/highslide-software/highcharts.com/tree/master/exporting-server developed by Highcharts
These exportservers are setup to remove the temporary created files. You have to change the code a bit to prevent this.
read also this article for more background information on Highcharts exportservers
This is going to involve much more than simply using highcharts. You are going to have to use some sort of wrapper that will actually render the chart/page on the server-side and then essentially output it as an image. The following are links taken from a post on the highcharts website.

My clients can enter text into textarea and have the option to use the markdown or textile filters for each textarea.
With some models (articles, newsletter, etc) they can upload images to associate with the model, which are displayed in a column next to the text of the text.
This worked fine for a while, but they have now told me that the want the ability to put the images INSIDE the text a specific positions.
What is the best way to go about this? I suppose I may have to use a wysiwyg for this, but would rather not. And how would this work for images which are not yet on the server, etc?
There are different directions you could go to:
Follow the path of Confluence, which released in their new version 4.0 a rewritten WYSIWYG editor, that stores as source XHTML, not any more wiki markup.
Leads to an update of all pages when migrating.
Was pretty difficult to implement. I do not know if they use any more the TinyMCE editor of previous versions.
Follow the format of markdown how to include images in your source format. So by typing: This is my text. !image.png! The inline image shows ..., you will have a format that is understandable.
You have to expand the interpretation, so that the !<filename>! will be mapped that is stored locally anyway.
You have to add clear-up dialogs for the images that are yet not known, so doing bulk uploads ...
You may provide a drag area on your view, that then shows the filename and gives examples how to include that inside the text area.
Go for something in between, by allowing users to drag images inside the editor. There are plugins written in Javascript that allow you to do that, e.g. UI Draggable for jquery
I have no idea how to integrate that image inside the text editor. Overlay?
So the second one is the easiest, and the user knows how to do it. If they only decide that this is the solution they want to have :-)
I think I'm going to use a combination of #2 above, and the Liquid templating engine.
I have an SVG file that I would like to display via Raphael (each svg file is a node in a tree I'm trying to draw, the actual connections of the tree will be made by raphael). I tried something like:
var vector_image = paper.image("test.svg", 50,50,50,50);
but no dice, seems only "real" image files like png or jpeg are accepted? I find this very strange as Raphael itself uses Scalable Vector Graphics.
Is there anyway (short of parsing the SVG files into javascript snippets and pasting them into the html document) to display existing SVG files using Raphael (or any other vector based javascript graphical engine?)
If parsing it will have to be, is there any easy way to do this, short of just manually scraping the files? I'm running this code on a Ruby on Rails server, so I'd like to avoid solutions outside this framework, if possible (I've heard of one PHP solution through this site...I'd rather code by hand than add another language onto this project).

It's currently not possible to display existing SVG with Raphael, and there are apparently no plans for the implementation of SVG editing (see this forum post).
As for alternative JavaScript libraries, a newer alternative is Snap.svg, which can load external SVG files via its Snap.load() function.
I'm implementing charts using The Ziya Charts Gem. Unfortunately, the documentation isn't really helpful or I haven't had enough coffee to figure out theming. I know I can set a theme using
chart.add(:theme, 'whatever')
Problem: I haven't found any predefined themes, nor have I found a reference to the required format.
If you install the ZiYa plug-in into your Rails application there should be a themes directory where you said. Just copy one of the existing themes, change its name to whatever you want, and then modify it however you like.
Another options for nice Flash charts is Open Flash Chart. I moved from Ziya/SWF Charts to Open Flash Chart when working on Flash charts in a Rails app I was working on. There is also a Rails plug-in for Open Flash Chart. Besides the fact that it is easier to work with, Open Flash Chart is open source, so if you can hack Flash you can customize it.
As I understand it, the themes are used by initializing the theme directory in your ziya.rb file like so:
Ziya.initialize(:themes_dir => File.join( File.dirname(__FILE__), %w[.. .. public charts themes]) )
And you'll need to set up the proper directory, in this case public/charts/themes. It doesn't come with any in there to start with as I recall. Are you having problems past this?
To partly answer my own question, there are some themes in the website sources which can be checked out at
svn co svn://rubyforge.org/var/svn/liquidrail/samples/charting
(then go to /public/charts/themes/)
