  1. 1. DataCoach.caTable vs. Graph :What are graphs and tables for ? Table and Graph represent a quantitative relationship between set of categories and set of quantitative values Categories: Department category and Q1 (Jan, Feb, March) categoryBudget Forecast 2012 Quantitative value: Budget in US $(Measure ofDepartment Jan Feb MarMarketing 83,333 62,465 79,456 Money)Sales 38,838 41,899 48,500HR 37,780 32,878 29,665Finance 58,976 51,786 55,346Total $218,927 $189,028 $212,967 US.$ 90,000 Budget Forcast Q1 2012 80,000 70,000 60,000 50,000 Marketing 40,000 Sales 30,000 HR 20,000 Finance 10,000 0 Jan Feb Mar Q1 2012

  9. 9. DataCoach.ca Table Design : What table columns you should sort by? • Numbers and dates both have natural order that can be sorted ascending or descending • Other data, such as the name of things (e.g., products, customers, and countries) use alphabetical order which is useful for lookup but is not meaningful otherwise • If items have a natural order that is meaningful , sort them in that order
  10. 10. DataCoach.ca Graph Design : What message graph can communicate?• Graph can encode quantitative values in form of :Points, Lines, Bars, Boxes, Shape with varying 2-D Area, Shape with color intensity• Quantitative relationship in graph :Time Series, Ranking, Nominal Comparison, Part-to-Whole, Deviation (single and Multiple), Correlation, Geospatial
  11. 11. DataCoach.caGraph Design : What is time series and how graph can display it?• Values display how something changed through the time(Yearly, monthly, etc.)• X axis of the graph usually provides time interval scale• Use lines when you have value for every interval of time Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 161,896 174,444 78,358 129,610 122,186 96,912 139,536 36,456 172,353 170,134 166,081 168,224 200000 180000 160000 140000 120000 100000 80000 60000 40000 20000 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

  13. 13. DataCoach.ca Graph Selection : What is a ranking relationship and what graphs can display it?• Ranking display how quantitative values relate to one another sequentially ,sorted by size from lowest to highest or vice versa• One axis of graph display categories labels and the other display quantitative values• Bars are natural choice for display Ranking unless quantitative scale dose not begin at zero, In this case Points are better choice 350 Order Management 300 Sales 250 200 Marketing 150 Manufacturing 100 50 Technology 0 Human Resource Finance Engineering 0 50 100 150 200 250 300 350
  14. 14. DataCoach.ca Graph Selection : What is a part-to-whole relationship and what graphs can display it? • Display how individual values that make up whole of something (e.g. total sales) • Pie charts and stacked bars can display part-to-whole relationship East West North South 6% 11% 80 East 44% West North South 70 39% 20 10 1
  15. 15. DataCoach.ca Graph Selection : What is a deviation relationship and what graphs can display it?• A deviation graph displays the degree to which one or more set of quantitative values differ in relation to a primary set of values• Bars (vertical and horizontal) can display deviation relationship Actual Plan Sales 89.57% Sales 36.15 346.69 Marketing -7.21% Marketing 298.22 278.17 Operations -32.54% Operations 159.05 120.00 Engineering 36.68% Engineering 214.89 339.36 Finance -43.27% Finance 389.13 271.60 Head Count 2012 Head Count 2012 - Variance from plan Actual Plan 100.00% 450.00 80.00% 400.00 60.00% 350.00 300.00 40.00% 250.00 20.00% 200.00 0.00% 150.00 -20.00% 100.00 50.00 -40.00% 0.00 -60.00% Sales Marketing Operations Engineering Finance Sales Marketing Operations Engineering Finance
  16. 16. DataCoach.ca Graph Selection : What is a correlation relationship and what graphs can display it? • Correlation graphs display the relationship between two paired sets of quantitative to demonstrate whether or not they are related, and, if so, the direction of the relationship (is positive or negative) 100000 90000 80000 Salary in US $ 70000 60000 50000 40000 30000 20000 55 60 65 70 75 80 85 Height in inches
  17. 17. DataCoach.ca Graph Selection : What is a geospatial display and how to display it on a map? • Geospatial displays feature the geographical location of values on a map • Points of different size and color intensity can be used to capture values
  18. 18. DataCoach.ca Graph Selection : What is a geospatial display and how to display it on a map? • Points of different size and color intensity can be used to capture values
  19. 19. DataCoach.ca What is overall strategy? • Should the message be presented in the form of a table or a graph? • If a table, which kind of relationship should it display? • Between single set of quantitative values and a single set of categorical subdivision • Between single set of quantitative values and the intersection of multiple categories • Between single set of quantitative values and the intersection of hierarchal categories • If a graph, which kind of relationship it display? • Time Series • Ranking • Part-to-whole • Deviation • Correlation • Geospatial • If a graph, which object or combination of objects for encoding the quantitative value work best? • Points • Lines • Bars • Boxes
