STACKED BAR 100%

Use when

• how the MIX shifts across periods or categories
• the key segment's share is the message
• 2 to 4 additive segments

Do not use when

• the total matters (use CH-PTW-01; 100% hides growth and shrinkage)
• more than 4 segments
• single-period share (a sentence or CH-PTW-06 does it better)

See instead

• the total itself matters: CH-PTW-01

Alternatives

• CH-PTW-01 (absolute stacked)
• CH-PTW-06 (waffle, planned)

Rules

• all columns equal height; the mix is the message
• the key (first) segment's share labeled above each column with the % sign
• segments identified by swatch + name at the last column, never a legend
• 4 segments maximum
• the title must state the share shift, not the totals

Never do this

• using 100% stacked when totals shrink (it hides decline)
• legend boxes
• labeling every segment share (label the key segment only)
• more than 4 segments

QA before delivering

• columns equal height
• key segment share labeled with %
• segment names at last column, no legend
• title states the share shift
• source line present bottom-left
