All modern browsers are supported as well as Internet Explorer 8 and above.
If you run into problems with IE8, IE9 or IE10 and get a error message saying IE7 is not supported, it may be because you are running the browser in IE7 compatibility mode. Here are directions on how to change the compatibility mode.
If you're using a Google Spreadsheet as your source, make sure your Google spreadsheet is public and published. Also make sure you don't have any empty rows in the spreadsheet since this can sometimes cause problems.
Timeline is optimized for 20-30 entries. If you have more entries, you run a risk of slow loading times, so test and make sure you are satisfied, or edit your timeline into less entries or a series of smaller timelines. La Nación created a timeline of all of the popes with over 250 entries.
There is a plugin for Wordpress.
Here is a link with some coding instructions.
If the Wordpress plugin is out of date you can use the iFrame embed method
Thumbnails are only shown from Flickr, Youtube, Vimeo etc. That was done for performance reasons. Having a very large image file as a thumbnail really slows down the timeline. Flickr, Youtube etc have actual thumbnail sized images that can be used that don't cause performance issues. You can also create your own thumbnails.
TimelineJS is all javascript, for any php questions please refer to another source.
Yes. See here for a hacking idea.
The display of the timeline is dynamic. It chooses a time interval that best matches the number of events there are with the amount of time that is covered.
Not at the moment.
The default number of rows is 3. If you are using tags and you have more than 3 tags, the number of rows increases to 6.
If the event is on the first day of the month and no time is specified it shows only the month. The same is true for year. If the event date is the first day of the first month of the year, it only shows the year.
No, but it's pretty easy to copy rows into a Google Spreadsheet. TimelineJS uses Google's API to access the data from the Google Spreadsheet and turns it into native TimelineJS json.
Yes. JSON is the best and safest format for feeding information into TimelineJS from a database. Just use your language of choice to create a json file from your database.
Yes! Just grab a copy of the template and replace the language with the language you want to create. You can find your language's two letter code here. Save the file and post it to the Google Group or you can do a pull request on GitHub.
Tags are essentially categories. You can have up to 6 of them to categorize events on the timeline. The events on the timeline will align with their category row. See the screenshot below
You can add dates that are B.C. by using negative years. For example, -100 would be 100 B.C.
