The chart without any highlighted grid cells.

The Graph (also known as the Chart) is a grid that appears at the end of every dream in LSD: Dream Emulator, as well as when selected from the main menu. According to the LSD Manual Cards, the Graph is a representation of the player's mental state after the previous dream. The current graph position (not the one at the beginning or end of a dream, but the one actively being updated as the player moves) is responsible for mostly every random event in the game.

Graph formula

The Graph depends on values that have been invisibly assigned to chunks (parts of the field, or level) and entities. All of this was discovered by hgs..

Definitions

Individual Value

Individual Value (IV) is a number assigned to individual chunks and characters. For chunks IVA is used and for characters IVB is used.

IV Addresses
Cumulative X-Coordinate IVA 0x91678 4-byte
Cumulative Y-Coordinate IVA 0x9167C 4-byte
Last-acquired X-Coordinate IVA 0x91674 1-byte
Last-acquired Y-Coordinate IVA 0x91675 1-byte
IVA counter 0x91680 4-byte
Cumulative X-Coordinate IVB 0x91688 4-byte
Cumulative Y-Coordinate IVB 0x9168C 4-byte
Last-acquired X-Coordinate IVB 0x91684 1-byte
Last-acquired Y-Coordinate IVB 0x91685 1-byte
IVB Counter 0x91690 4-byte

Lank Value

Lank value (LV) is a score between -2 and 2 that larger Individual Values (IV) are capped to.

Individual value to Lank value
Individual value Lank value
IV≧6 2
3≦IV≦5 1
-2≦IV≦2 0
-5≦IV≦-3 -1
IV≦-6 -2

Final equation

A = Cumulative X-Coordinate IVA divided by IVA counter
B = Cumulative Y-Coordinate IVA divided by IVA counter
C = Lank value of Last-acquired X-Coordinate IVA
D = Lank value of Last-acquired Y-Coordinate IVA
E = Cumulative X-Coordinate IVB divided by IVB counter
F = Cumulative Y-Coordinate IVB divided by IVB counter
G = Lank value of Last-acquired X-Coordinate IVB
H = Lank value of Last-acquired Y-Coordinate IVB

((A+C)+(E+G))/2=x
((B+D)+(F+H))/2=y

Equation without IVB (used if no characters have been seen)

(A+C)=x
(B+D)=y

Rules to apply before getting the final values

Rounding rule

If the addition for A+C, B+D, E+G, or F+H results in a value of ≦-10, convert to positive 9.
If the addition for A+C, B+D, E+G, or F+H results in a value of ≧10, convert to negative 9.

Decimal rule

If A, B, E, or F (the cumulative division values) end up containing a decimal, remove everything after the decimal instead of rounding (5.944 -> 5)

Connection to starting Field

Graph-spawn-map-seesaa.png

The score of the previous night's dream is used to determine which field the next dream starts in. This image[1] shows the correspondence, with the points under each field name referring to how many total spaces it has on the Graph.

For Day 001 and after every Special Dream, the graph is set to (0,0) (which corresponds to Linen's nose). This means it will start in Bright Moon Apartment.

Trivia

  • It's possible to score outside the main chart graphic. The full area is actually a 19x19 square.
