Stackmix

StackMix creates stacked bar charts from category data. Build sheets with multiple categories, each containing labeled segments and values, and view vertical stacked bars that show part-to-whole composition. Save sheets, edit segments inline, preview before saving, and compare two sheets side by side.

Perfect for budget breakdowns by team, time allocation blocks, or multi-layer survey results. StackMix renders charts locally with Core Graphics—no network, no third-party SDKs, no account required. All data stays on your device.

StackMix is an offline stacked-bar notebook for clear composition charts from manually entered data.
