3 Logging in to gdiac You will need to be behind the Cornell firewall to login to gdiac.cs.cornell.edu Easiest way to do this is to install the VPN: Connect to: cuvpn.cuvpn.cornell.edu Username: Password = your netid password For more information, see:

4 Logging in: SFAM Set your SFAM password: 1. Open a VPN connection to the department VPN 2. Visit 3. Click SFAM 4. Set password 5. Wait a little bit (30-60 minutes) for server to update With the VPN active, SSH into gdiac: ssh <your_netid>@gdiac.cs.cornell.edu replace <your_netid> with your netid you can use PuTTY from Windows machines:

5 Data Visualization Methods Burndown Charts Heatmaps State transition diagrams

6 Burndown Charts After x levels/seconds, how many people are playing?

7 Burndown Chart 100 % of players 0 Level

8 Unexpected Drop 100 % of players 0 4 Level

9 Unexpected Drop 100 % of players 0 4 Level

10 Usage: find unexpected drop Source: Sleep Fighter

11 Usage: track releases Source: That s How We Roll

13 Making a Burndown Chart Player Levels Completed Level % Remaining = percentage of with more than levels

14 COUNTIF(range, criteria) B2:B8 >= &D2

15 Making a Burndown Chart Level % Remaining Player Levels Completed = 9COUNTIF(B2:B8, 7 18 >= &D2) 0

16 Making a Burndown Chart Player Levels Completed Level % Remaining = COUNTIF($B$2:$B$8, >= &D2) 0

17 Making a Burndown Chart Level % Remaining Player Levels Completed = COUNTIF($B$2:$B$8, >= &D2) / 7

18 Completed Burndown Chart?

19 Completed Burndown Chart % Remaining Burndown Chart for Levels Completed Level

20 Important Notes % Remaining Must have axis label Burndown Chart for Levels Completed Must start at 100% Must be able to read the font Level Must have axis label Must have title Line must be visible

21 Data Visualization Methods Burndown Charts Heatmaps State transition diagrams

22 Heatmaps

23 What are heat maps good for?

24 Making a heat map Death X Y

25 COUNTIF(range, criteria)

26 COUNTIFS(range 1, criteria 1, range 2, criteria 2 )

27 Making a heat map Death X Y = COUNTIFS(B2:B8, = &E2, C2:C8, = &F1)

28 Making a heat map Death X Y = COUNTIFS($B$2:$B$8, = &$E2, $C$2:$C$8, = &F$1)

32 Completed Heatmap? Level 10 Heatmap Zombify, 2014 (with Erik s additions)

33 Heat maps should support analysis Not the point themselves Support a particular point Zombify, 2014 (with Erik s additions)

34 Completed Heatmap This pathway was supposed to be easy Enemies Many players died here Figure 1. This heatmap shows an unexpected problem with the game design. Although this hallway was supposed to be easy, many players died here. We will try to resolve this problem by spacing the enemies further apart. Zombify, 2014 (with Erik s additions)

35 Completed Heatmap Needs level context Needs annotations Enemies This pathway was supposed to be easy Many players died here Figure 1. This heatmap shows an unexpected problem with the game design. Although this hallway was supposed to be easy, many players died here. We will try to resolve this problem by spacing the enemies further apart. Needs explanation Zombify, 2014 (with Erik s additions)
