Lumenize

Copyright (c) 2009-2013, Lawrence S. Maccherone, Jr.

Illuminating the forest AND the trees in your data.

Lumenize is a collection of tools for analyzing and making awesome visualizations out of your data.

Documentation and source code

Features

  • Fast, light, flexible client-side OLAP Cube with hierarchical rollup support
  • Create aggregations from temporal data models like Rally's Lookback API
    • TimeSeriesCalculator - Show how performance changed over time. Visualize cumulative flow.
    • TimeInStateCalculator - Calculate the ratio of wait to touch time. Find 98 percentile of lead time to set service level agreements.
    • TransitionsCalculator - Throughput. Velocity.
  • Bundled with the tzTime library (same author) for timezone precise x-axis. Knockout weekends, holidays, non-work hours, etc.
  • Tested - Over 600 tests (plus over 400 tests in tzTime)
  • Documented (Lumenize) (tzTime) - Robust documentation and examples
  • DocTested - The examples will always match the code because it fails automated testing when they don't

Usage in a browser

To use in a browser, either host it on your own site, or if your volume is low enough, you can directly hit the github pages for the deploy version:

<script type="text/javascript" src="https://cdn.rawgit.com/lmaccherone/Lumenize/v{{version}}/deploy/lumenize-min.js"></script>

Replace {{version}} with the version of Lumenize you wish to use (probably the latest). See the Changelog section for information about versions. Example:

<script type="text/javascript" src="https://cdn.rawgit.com/lmaccherone/Lumenize/v1.0.3/deploy/lumenize-min.js"></script>

The package is fairly large ~260KB but most of that is the embedded timezone files which compress really well.

Then at the top of the javascript where you want to call it, put the following:

var lumenize = require('./lumenize');

And call it like this.

var stdDev = lumenize.functions.standardDeviation([20, 30, 50]);

Usage in node.js

To install, run the following from the root folder of your project:

npm install lumenize --save

Then in your code:

var lumenize = require('lumenize')

Changelog

  • 0.7.1 - 2013-07-07 - Added simple table output formatting. Added significance to OLAPCube output. Evenutally, OLAPCube.toString will use table.toString(), but not yet. Bug fixes.

  • 0.7.0 - 2013-06-01 - Backward breaking change. Histogram significantly upgraded. The old clipping histogram has been moved to histogram.clipping(). The new functionality is more complete and general purpose.

  • 0.6.11 - 2013-05-19 - Added point to projection series for startIndex and now use angle instead of slope for v-optimal projection algorithm

  • 0.6.5 - 2013-02-09 - Fixed bug on TimeSeriesCalculator where toDateCell was including more than it should and was possible located wrong. Changed histogram to use Q3 + 1.5 * IQR as outlier detector and added option to not do outlier clipping. Lots of little documentation updates. Updated to tzTime 0.6.5.

  • 0.6.4 - 2013-02-08 - Fixed bug where Friday current will double count Friday in labels by adding a tick on Saturday. Now it advances all the way to Sunday night.

  • 0.6.3 - 2013-02-07 - Updated to tzTime 0.6.4 (potentially backward breaking to those who were incorrectly instantiating Time objects from an ISOString without providing a timezone) Also, changed the way TimeSeriesCalculator takes into account the start so it works as expected if it falls on a weekend. This is also potentially backward breaking.

  • 0.6.2 - 2013-02-06 - Close issue #10

  • 0.6.1 - 2013-02-03 - Updated to the laster version of tzTime 0.6.2

  • 0.6.0 - 2013-02-03 Major backward breaking changes

    • Time, Timeline, and TimelineIterator have been split out to their own package, tzTime
    • Lumenize has been simplfified down to four main classes: TimeSeriesCalculator, TransitionsCalculator, TimeInStateCalculator, and OLAPCube
    • There are still a few addional helpers for data transformation and a histogram calculator function.
    • The three main calculators implement the same interface and take similar config objects.
    • They provide a superset of all of the functionality previously found in Lumenize.
    • They all use the OLAPCube abstraction so they are much easier to understand, maintain, and upgrade.
    • They now all support incremental updating, and serialization so you can cache results of an earlier calculation and restart justfeeding in the updated information.
    • All this AND significant performance gains.

    Things removed and gone forever:

    • Removed the concept of an "AtArray" and any functions that used it including deriveFieldsAt, aggregationAtArray_To_HighChartsSeries, groupByAtArray_To_HighChartsSeries, and snapshotArray_To_AtArray
    • Similarly, the function-form of timeSeriesCalculator and timeSeriesGroupByCalculator have been removed. Use the class-form replacement.
    • GroupBy functionality is now contained in the TimeSeriesCalculator. There is no seperate class for it like there was a seperate function for it before.
    • Removed aggregate, derive, and groupBy. Their functionality is now contained in the 3 main calculators.

  • 0.5.8 - 2013-01-31 - TimeSeriesCalculator now includes groupBy support. There will be no TimeSeriesGroupByCalculator.

  • 0.5.7 - 2013-01-27 - TimeSeriesCalculator evolved based upon learning from Burn Chart

  • 0.5.6 - 2013-01-24 - TimeSeriesCalculator class introduced (incremental, OLAP, etc.)

  • 0.5.5 - 2013-01-17 - Histogram now works all the way down to 0

  • 0.5.4 - 2013-01-17 - Histogram now works for bucketCount < 3

  • 0.5.3 - 2013-01-13 - Bug fix to work with Rally's Throughput chart

  • 0.5.2 - 2013-01-13

    • Added TransitionsCalculator using OLAPCube
    • OLAPCube now allows for keepTotals on individual dimensions while still supporting the global config.keepTotals

  • 0.5.1 - 2013-01-06 Backward breaking change

    • TimeInStateCalculator now requires you to specify config.trackLastValueForTheseFields for any fields you want the last value maintained. Previously, the _ValidTo was automatically tracked.
    • OLAPCube now has flattened input and flattened output
    • Minor bug fixes

  • 0.5.0 - 2012-12-15 Major backward breaking changes - not released to npm

    • Major refactor of names/variables for inclusion in Rally's App SDK
    • All functions that previously started with a $ no longer do
    • $push() is now values()
    • $addToSet() is now uniqueValues()
    • More parameters are pushed into the config Object parameter
    • OLAPCube introduced. It's a great general purpose calculator and surprisingly it is as efficient as the hand-coded calculators. I reimplemented the TimeInStateCalculator to use the OLAPCube, which gave it incremental updating for free.
    • ChartTime is now Time, ChartTimeRange is now Timeline, ChartTimeIterator is now TimelineIterator. All three have various other backward breaking changes mostly having to do with defaults, method names, and method signatures. There are no semantic changes.
    • ChartTimeInStateCalculator is now TimeInStateCalculator.

  • 0.4.8 - 2012-12-08 - Turn off prefer global

  • 0.4.7 - 2012-12-08 - Updated dependencies

  • 0.4.6 - 2012-12-06 - More testing build and automatic npm publishing

  • 0.4.5 - 2012-12-06 - Testing build and automatic npm publishing

  • 0.4.4 - 2012-12-06 - Fixing issue with README.css showing up as cover page on npm

  • 0.4.3 - 2012-11-28 - Cleaning up doc issues

  • 0.4.2 - 2012-11-28 - Playing with using git tags for keeping old versions

  • 0.4.1 - 2012-11-28 - Playing with using git branches for keeping old versions

  • 0.4.0 - 2012-11-27 Backward breaking change

    • No longer required/allowed to call Time.setTZPath()
    • Using JSDuck for documentation now
    • Build system now keeps old deploy versions
    • Pre-compiled directory removed
    • Bug fix for TimeInStateCalculator and snapshotArray_To_AtArray. They now sort (correctly). snapshotArray_To_AtArray will now also propertly remove from later ticks any entity that falls out of scope. Previously, deletions were not registered correctly by snapshotArray_To_AtArray.

  • 0.3.0 - 2012-10-13

    • Support for instantiating Time objects relative to now using strings (e.g. 'this day in Pacific/Fiji')
    • Added tests and fixed some bugs for timelineConfigs

  • 0.2.7 - 2012-10-10 Backward breaking change

    • Change to the structure of the data returned by groupBy() to match groupByAt()
