This is the core module in sheetsee and is included in all builds. It contains the functions for building your custom file as well as the basic data manipulation functions.
Tabletop.js will fetch the data from your spreadsheet and return it as an array of objects. Sheetsee.js has functions built in to help you filter or reorganize the data if you'd like.
This takes in your data, an array of objects, and searches for a string, groupTerm, in each piece of your data (formerly the cells of your spreadsheet). It returns the number of times it found the groupTerm.
getGroupCount(data, "cat")
// returns a number
Given your data, an array of objects, and a string column header, this functions sums each cell in that column(so this collumn you mention best have numbers).
getColumnTotal(data, "cuddlability")
// returns number
A really simple function that builds on getColumnTotal() by returning the average number in a column of numbers.
getColumnAverage(data, "cuddlability")
// returns number
This will return an array of object or objects (if there is a tie) of the element with the lowest number value in the column you specify from your data.
getMin(data, "cuddlability")
// returns array
This will return an array of object or objects (if there is a tie) of the element with the highest number value in the column you specify from your data.
getMin(data, "cuddlability")
// returns array
Create variables that are the sums, differences, multiples and so forth of others. Lots of info on that here on MDN.
var profit09 = Sheetsee.getColumnTotal(data, "2009")
var profit10 = Sheetsee.getColumnTotal(data, "2010")
var difference = profit09 - profit10
You don't have to just create tables of your data. You can have other portions of your page that show things like, "The difference taco consumption between last week and this week is..." These are easy to create with JavaScript math functions and knowing a little bit more about icanhaz.js.
Takes data as an array of objects, a string you'd like to filter and a string of the category you want it to look in (a column header from your spreadsheet).
getMatches(data, "dog", "kind")
Returns an array of objects matching the category's filter.
[{"name": "coco", "kind": "dog"...}, {"name": "wolfgang", "kind": "dog"...},{"name": "cooc", "kind": "dog"...} ]
Takes data as an array of objects and a string for category (a column header from your spreadsheet) you want tally how often an element occured.
getOccurance(data, "kind")
Returns an object with keys and values for each variation of the category and its occurance.
{"dog": 3, "cat": 3}
If you use getOccurance() and want to then chart that data with d3.js, you'll need to make it into an array (instead of an object) and add colors back in (since the hexcolor column applies to the datapoints in your original dataset and not this new dataset).
This function takes in your data, as an object, and an array of hexidecimal color strings which you define.
var kinds = getOccurance(data, "kind")
var kindColors = ["#ff00ff", "#DCF13C"]
var kindData = makeColorArrayOfObjects(mostPopBreeds, breedColors)
It will return an array of objects formatted to go directly into a d3 chart with the appropriate units and label keys, like so:
[{"label": "dog", "units": 2, "hexcolor": "#ff00ff"}, {"label": "cat", "units": 3, "hexcolor": "#DCF13C"}]
If you pass in an array of just one color it will repeat that color for all items. If you pass fewer colors than data elements it will repeat the sequences of colors for the remainder elements.
If you're using data, the data directly from Tabletop, you'll need to format it before you use the d3 charts. You'll need to determine what part of your data you want to chart - what will be your label, what your charting, and what will be your units, how many of them are there (this should be a number).
var data = [{"name": "coco", "kind": "dog", "cuddablity": 5}, {"name": "unagi", "kind": "cat", "cuddlability": 0}]
For istance, if from our original data above we want to chart the age of each cat, we'll use:
Sheetsee.addUnitsLabels(data, "name", "cuddlability")
Which will return an array, ready for the d3 charts:
[{"label": "coco", "kind": "dog", "units": 5}, {"label": "unagi", "kind": "cat", "units": 0}]
