Drawing markup and capturing the view

Markup lets you draw directly on the chart to explain a finding, and Capture turns the current view into a shareable image.

Drawing markup

  1. Click “✏️ Markup” in the Tools row.
  2. Pick a draw tool: “↗ Arrow”, “◯ Circle”, “□ Box”, “✎ Pen” (freehand), or “T Text”.
  3. Choose a color and a stroke width, then click-drag on the chart to draw (click to place a text note).
  4. Use “↶ Undo” to remove the last shape, or “Clear all” to remove everything.
Markup sticks to the data — shapes move and scale with the chart as you pan and zoom, so your callouts stay on the features they point to.

Text notes on more than one line

The text-note box works like the annotation label box: Shift+Enter inserts a newline, Enter commits the note, and Escape discards it. Clicking away commits too. Multi-line notes are drawn one line per row on the chart.

Editing drawings

“⌖ Select” is the first tool in the row and the one the Markup panel opens on. In Select mode, clicking a drawing selects it — a dashed halo and its handles appear, and a small toolbar floats just above it. The draw tools are unchanged; switch to one of those when you want to create something new instead.

You don't have to click exactly on a thin stroke: Overtrace allows about six pixels of slack around a line, and a little more around a resize handle.

Capturing the view

  1. Click “📷 Capture” in the top view-toggles.
  2. Choose “Download PNG” to save an image, or “Copy to clipboard” to paste it straight into a report or message.
An image is a dead end — the recipient can't pan it. To hand over drawings someone can keep working with, export a session file instead: markups travel in both Full and Overlay-only sessions. See Session files. Note that markups are the one overlay that doesn't cross between synced windows.

FAQ

Can I draw on the chart to point out a finding?

Yes. The Markup tool provides arrows, circles, boxes, freehand pen, and text. Shapes stick to the data and move with pan and zoom.

Can I change a drawing after I've made it?

Yes. In “⌖ Select” mode, click a drawing to select it, then drag its body to move it, drag a handle to reshape it, or use the floating toolbar to change its color, stroke width or text. Delete or Backspace removes it.

How do I export the chart as an image?

Use the Capture button to download a PNG or copy the current view to your clipboard.
