Edit Prism charts in Office.
On your Mac.

On Windows, double-clicking an embedded GraphPad Prism chart just opens it for editing. On a Mac, it never has — so you rebuild from a screenshot, or message a colleague with a PC and wait. Refractions closes that gap: scan the slide → click the chart → Update.

Why Refractions

Windows could. Your Mac couldn't. Now it can.

GraphPad Prism charts live inside your PowerPoint, Word, and Excel files as embedded objects. On Windows, you double-click one and edit it in place. On a Mac, you never could — so fixing a single chart meant borrowing a PC. Refractions ends that.

On Windows

Double-click the embedded chart. Prism opens, you make your edit, and it updates right there in the slide.

This has always just worked.

On a Mac · the old way

Double-clicking does nothing useful. So you rebuild the chart from a screenshot — or send the file to a colleague with a PC and wait for it to come back.

Slow, lossy, and not really yours to fix.

On a Mac · with Refractions

Click the chart in the task pane, edit it in Prism, hit Update. The same edit-in-place power Windows always had — now native to your Mac. No PC, no borrowed laptop, no waiting on a colleague.

What it does

Built for the workflow that actually exists.

No Windows VM. No screenshot dance. The file stays a real OLE-embedded Prism object, so colleagues on Windows can still double-click to edit.

One click to open

Pick a chart in the task pane. Refractions extracts the embedded .pzfx and opens it in Prism — no Save As dance.

Automatic image update

Click Update slide and Refractions writes the new .pzfx back into the OLE container and refreshes the preview image.

Stays Windows-compatible

The PPTX stays a real OLE-embedded Prism file. Send it to colleagues on Windows and they can double-click to edit, exactly like before.

How it works

Three clicks. No theatrics.

  1. 1

    Scan the slide

    Open the task pane on any slide. Refractions lists every Prism chart it finds, with a thumbnail.

  2. 2

    Edit in Prism

    Click the chart. Refractions pulls out the embedded .pzfx and opens it in Prism.

  3. 3

    Refract it back

    Make your edits, click Update slide. Refractions re-embeds the file and refreshes the preview image.

How seats work

Each seat activates Refractions on one Mac, for one human. Whoever buys becomes the Manager for the subscription: they assign every seat to a person by name and email — including, if they want, one to themselves. Each person gets their key by email and manages their own activations from the desktop app. The Manager never sees individual keys.

Common scenarios

  • Solo researcher: buy 1 seat — assign it to yourself.
  • Small team (lead + 4): buy 5 seats — assign one to yourself, four to your team.
  • Core facility: buy 10+ seats, reassign as people leave.

Seats are reassignable — if a teammate leaves, revoke their seat and assign it to someone else. The buyer's own access can't be removed by a co-manager (a safety invariant against lockout).

FAQ

Questions, briefly answered.

Yes — Refractions runs on macOS 14 or later, and that's the whole point. Editing an embedded Prism chart by double-clicking only ever worked on Windows; on a Mac it never has. Refractions brings that edit-in-place flow to the Mac, so you don't need a PC — or a colleague who has one — to fix a single chart. On Windows, you don't need Refractions at all.
Prism 9 and later (modern .pzfx format). Prism 8 support is best-effort.
No. The document stays a real OLE-embedded Prism file. Windows users double-click as normal.
Open the Refractions desktop app on either Mac, go to Manage activations, and deactivate the old machine — then activate the new one. No support ticket needed.
Every seat is $29 per year — no volume discount, no tier markup. Buy one for yourself, or ten at once if you're buying for a group. Each seat activates one Mac for one human. Whoever buys becomes the Manager and assigns every seat to a person by name and email — including, if they want, one to themselves. You can add or remove seats anytime from the billing portal.
No. All processing happens locally on your Mac. The only network calls are license validation against refractions.app.
