Polygon editing: select a gate, then Ctrl/⌘-click an edge to add a point or right-click a vertex to remove it (minimum three). While drawing, right-click to undo the last point.

Start with Example Data in Files, or add your own FCS or CSV files. Choose your parameters and plot type in Data.

Choose a gate tool, then drag on the plot. For a polygon, click its corners and press Enter or double-click to finish. Double-click a gate to view its population and draw child gates.

Right-click gates to apply them across samples. Click an axis label to change its range; right-click the plot to adjust its style.

Quadrants: press Q and click the intersection. Drag the centre to move all four gates; hover over either divider and drag to tilt it. Undo with ⌘Z / Ctrl+Z; redo with ⇧⌘Z / Ctrl+Y. Drag sidebar edges to resize, or double-click to reset.

Shortcuts: Q quadrant · S select · R rectangle · E ellipse · P polygon · G histogram segment · Z zoom · Esc cancel.

Files and exports stay on your device. Workspace files contain your sample data. Desktop browsers with a mouse or trackpad work best for gating.
