I'm looking for an aggregate data set which shows three datasets of related data, and a percentage share for each over time. So for example, it might show manufacturers share over time for each of 3 categories of product. I want the shares to total 100% in each category. Another example might be 3 portfolios of similar stocks over time. I want this for my cross section visualization of a series of nested shells. Each axis will be a different dataset--the equivalent of an animated pie chart. From the middle to the outside will equal 100%. So 5 dimensional data.

Clarification: 5 dimensions: Time, categories (companies, for example) and 3 share dimensions, each of the 3 total 100%. The values of category are preferably the same for the 3 share dimensions (not the share values), but not necessarily.

I'm sorry if this is vague, I don't have a particular type of data in mind. At least 5 measurements in the time dimension would be nice. Something cyclical in time would be nice too. I can munge data. Would something on data.gov work? I'm basically a novice at data gathering, and would trade a visualization for data, Thus:

Once the 3D visualization is complete, I will post the visualization in source form here. Here it is as it now stands: http://coderextreme.net/earth/world.html I will animate each plane of the cross-section individually over time.

  • This is really, really vague. Technically, anything could answer this question. (land use, agricultural output, weather reports, employment data, etc.)

  • A good way to respond to this message would be market share by manufacturer for smartphone, tablets and smartwatches by quarter. Commented May 23, 2015 at 12:59
  • If you have the answer to the question already, why did you ask it? It's not like this is a question with a specific enough answer that others might find useful ... it reads more like 'I have a homework assignment'.

  • @Joe, have you had your coffee morning? I have a visualization, but made up data. I would like real data. No I am not an uber @ data-analysis or a student. I am trying to learn how to find information. The UCI repository is one place. One thing I don't know how to do is find quarterly shipped goods, although I suspect that It could be found looking at companies quarterly reports. I am not a stock/investment expert either. I just want some data to fill into my visualization. I realize I could so some searches myself, but I'm unfamiliar with searching for this type of data. Commented May 23, 2015 at 16:05
  • @Joe, so far all the "answers" I have found cost $. I am looking for open data, not $50 a month. Commented May 23, 2015 at 18:15

For these kind of questions I think the most useful place to search is the UCI Machine Learning Repository.

Use the filters on the left menu bar to select certain types of datasets. For example, "Time series". You'll find data sets like this:

The dataset comprises motion sensor data of 19 daily and sports activities each performed by 8 subjects in their own style for 5 minutes. Five Xsens MTx units are used on the torso, arms, and legs.

  • Looking for numerical data which I can sum to equal 100% in 3 dimensions, like 3 pie charts. I don't see how to convert sensor data in x,y,z to %. I would understand if it was phi and theta. Commented May 23, 2015 at 12:45
  • This answer fits better under my question under the metadata tag. Commented May 23, 2015 at 16:11
  • Apparently I can't search @ UCI by percentage, share or count for attribute type? Am I missing something? Commented May 23, 2015 at 17:01
