I'm afraid this is the legend for the "control flow" view rather than
the resource view.

There currently exist no legend for the resource view AFAIK, even in
html format.

One could create a legend by looking at 
lttv/modules/gui/resourceview/drawing.h:

typedef enum _draw_color {
                COL_BLACK,
                COL_WHITE,
                COL_RUN_USER_MODE,/* green */
                COL_RUN_SYSCALL,  /* pale blue */
                COL_RUN_TRAP,     /* yellow */
                COL_RUN_IRQ,      /* orange */
                COL_RUN_SOFT_IRQ, /* red */
                COL_WAIT,         /* dark red */
                COL_WAIT_CPU,     /* dark yellow */
                COL_ZOMBIE,       /* dark purple */
                COL_WAIT_FORK,    /* dark green */
                COL_EXIT,         /* "less dark" magenta */
                COL_MODE_UNKNOWN, /* white */
                COL_UNNAMED,      /* white */
                NUM_COLORS } draw_color;


typedef enum _draw_color_cpu {
                COL_CPU_UNKNOWN,
                COL_CPU_IDLE,
                COL_CPU_BUSY,
                COL_CPU_IRQ,
                COL_CPU_SOFT_IRQ,
                COL_CPU_TRAP,
                NUM_COLORS_CPU
} draw_color_cpu;

typedef enum _draw_color_irq {
                COL_IRQ_UNKNOWN,
                COL_IRQ_IDLE,
                COL_IRQ_BUSY,
                NUM_COLORS_IRQ
} draw_color_irq;

typedef enum _draw_color_soft_irq {
                COL_SOFT_IRQ_UNKNOWN,
                COL_SOFT_IRQ_IDLE,
                COL_SOFT_IRQ_PENDING,
                COL_SOFT_IRQ_BUSY,
                NUM_COLORS_SOFT_IRQ
} draw_color_soft_irq;

typedef enum _draw_color_trap {
                COL_TRAP_UNKNOWN,
                COL_TRAP_IDLE,
                COL_TRAP_BUSY,
                NUM_COLORS_TRAP
} draw_color_trap;

typedef enum _draw_color_bdev {
                COL_BDEV_UNKNOWN,
                COL_BDEV_IDLE,
                COL_BDEV_BUSY_READING,
                COL_BDEV_BUSY_WRITING,
                NUM_COLORS_BDEV
} draw_color_bdev;

This, along with the color definitions in drawing.c, defines which color
is associated with each resource.
