Test Tubes

Test Tubes is part of Chartissimo's Tech & Digital collection — presets that borrow from screens, circuits, and product-design surfaces. Scientific measurements. The palette carries 6 colors tuned to read cleanly on a white background, which matters when the audience is engineering-literate and will notice a lazy gradient immediately. Reach for this style on product launches, dashboards embedded in a deck, or any chart that needs to feel native to the software it's describing. It renders as column charts equally well, so you can keep one visual system across a deck that mixes bar, column, line, and pie — without a single slide feeling like a template.

How to apply this style

1. Open Chartissimo with Test Tubes pre-selected Click the launch button on this page — the app loads with Test Tubes already selected, so you can skip straight to pasting your data.
2. Paste your data Drop a CSV, paste from a spreadsheet, or type values directly. Chartissimo handles small tables (under ~25 rows) best; larger datasets should be aggregated first.
3. Pick your chart type Choose column chart or any other type this preset supports. The visual language stays consistent across chart types, so you can swap later without losing the look.
4. Generate and export Hit generate, wait a few seconds, then export as PNG or SVG. Drop it straight into your slides, doc, or blog post.
