I am interesting in finding a project timeline software that has an interactive visualization of the actual timeline. This means that if the date of a certain event has moved, you can just click+hold it and slide it to the new date.

I need something that can be easily modified without having to enter/alter any text. So, instead of going to a certain event and editing the actual date, you can just move its marker further from the initial position.

I need this because the dates on my project change often and there are never 100% certain dates. This would allow us to move the marker to a 'proposed date' and keep on doing this until we have certainty.

An alternative would be a timeline software with which you can easily right click and "enter a new event". This way we could just delete and easily add a new mark on the 'proposed date'.

Do you guys know any (open source preferably, but not necessarily) project timeline software that has this type of user interaction implemented?

  • Online/standalone? Program, code or API (software is too generic)? If standalone, what OS? Budget? Number of data points/complexity of projects (i.e. hierarchies/dependencies)? What is wrong with the many project management/planning packages available? Please edit your question and answer all these questions.

  • Online/standalone - irrelevant Program, code or API - all OS - irrelevant Budget - irrelevant at this point. Can't set a budget without knowing that it exists? Number of data points/complexity of projects - Can this be a limitation? (less than 500 data points) What is wrong with the many project management/planning packages available? - They don't suit my needs as good as something like Timeline as Matthew Lock suggested due to the method of editing the dates. A lot of times we just need to "push" the date without having something specific.

  • How difficult is reading? I even provided you an edit link in my comment.

  • No, reading is not difficult, thank you for the implied insult, but doing something without logic is. You basically give zero input, ask a bunch of irrelevant details that would imply you have so many applicable answers to my request and on top of that insult me even though I clearly mentioned that I've received an appropriate answer from Matthew Lock. So, how difficult is reading?

How about Timeline? It's an open source desktop application that runs on most platforms and lets you drag events to new dates, or drag their start and end dates for date ranges.
