How to Create a Wheel View 150 Green Street San FranciscoA short tutorial to get you started. California 94111 United States 1

Start with a spreadsheetHere we use a sample file to illustrate how tocreate a wheel chart with “X” as the hub.Note in our spreadsheet that relations are Attribute name Datesexpressed as the names in two adjacentcolumns (“G is related to X”).You also need dates (Excel Formatted Cells) Pairs = relationand names for you‟re your attributes; in thiscase “Sample Data”. 2

Use the Excel Add-in to tag data; two adjacent columns to make relationsLaunch the Quantum4D Excel add-in andselect the rows with your relations; thenpress “Object(s)” button. This will highlightthe two columns as red. Objects 3

You’ll also need to indicate your dates and the name of this data series.Then select the attribute name and press the“attribute(s)” button. Then the same for“Date(s)”.When you‟ve done this the “Commit” button Select & press “Attribute(s)”will be enabled. Select and press “Date(s)” 4

When you press create, you will be prompted to choose directionalityFrom column A to column B is <-No direction is –From column B to column A is ->Bi-directional is <->If you have different data for both A to X andX to A; put each pair aligned as shownbelow: A X 5 X A 4 In this tutorial we‟re choosing “->” (values are from A,B,C… to X)This will generate two arrows for the pair. 5

You’ll then be prompted to save the fileThe add-in creates a new “Q4D” sheet inyour workbook when it saves. This holdsthe tags that Quantum4D uses to import yourdata.Later you can modify the ranges they specifyif you increase the data in your import.To do that change the references in columnB to include your new entities, dates or data. Your Data is ready for Import into Quantum4D 6

Launch Quantum4D and create a new space where we’ll import the data.Launch Quantum4D. Then double click on arepository; we suggest you start with “MySpaces.” This is your own local database onyou computer.Once it is open, right click and choose “newspace” as shown to the right. Name yourspace and you‟ll automatically enter it. (it will be empty at first so the screen won‟t look different) Create a new Workspace in My Spaces. 7

Right click your new space and import the data.Once created you‟ll see your new space as ablue icon in the tree. Right click that andselect “Import...”Then select the tagged file saved using theAdd-in and import. Your new space will be blue (this indicates it’s your current space). 8

Select the Wheel Chart from the Lens menu of options.The wheel chart is pre-configured andavailable under more… and then expandNetwork Graph (shown below).Drag the lens onto the 3D workspace. 9

You will then be prompted to choose the data and center objectThe data we imported is on the relations,which comes up first.Select the sample data and press Map.There is no data available on objects soselect ignore.Then choose x as The Wheel Chart defaults to show relative size of width asyour center object. the raw data and color as % change between dates. So G->A has the highest % change in October and A->X has the highest value. 10

Other basic things you can try nowAnimate Time Series• Press the play button on the tool bar or manually scroll through time using slider at the top of the 3D space.Display Values• Click in the 3D space and press the “w” key; this will show the width values.• Now press the “c” key; this will display the color value.Change Values• On the lower right you should see a Lens Settings controls. You can double click either Width or Color and changed the period for % chg.• You can also add annotation (i.e. color is a percent – see drop down and instructions in Reference guide). 11

Other more advance things you’ll find in the Q4D sample and online.Remote attributes: to get data off the relation onto objects; use “relation(a)” on the object group for the feature and choose a fromthe drop down list on the feature panel. – See attached Remote Attributes quick tutorial for more details. – In the sample, try adding “sum” to the start of the formula on radius for objects; so that it reads as sum(relation(a)) note that the middle object gains a value.Ranking: the key formula is rank(a,peers(a)))<=10 where 10 can be switched to 20 for „top 20‟ etc… use with visibility. – See attached Ranking quick tutorial for more details – Also, in the sample file, you‟ll find that you can apply a working version of this formula by checking the box on the feature panel to turn on visibility (all preconfigured).Alerts: to learn more about alerts, connect to an existing Quantum4D databases and see what‟s changing in the world. – Go to the main menu, applications> Alert Watch and click o.k. (no need to choose a date range limiter). This should produce a long list of spaces where alerts have been applied. – You should be able to copy and paste the formulas from those. Note – you‟ll want to set the standard deviation threshold to higher values to more volatile corridors.Proportion of total: as a bonus in the sample, we‟ve mapped „proportion of total‟ expressed as a percent. To do that you need tocreate a sum of children on the relations group and then map strength to “a/b” and expressed it as a percentage of the total. 12
