Graphical Analysis and other Vernier apps require a minimum level of functionality from the ChromeOS to function. From time to time we raise the minimum ChromeOS level as new functions are used. If your Chromebook is not up to date, it may not have a sufficiently recent OS to run the current releases.

One possible workaround is to use the Graphical Analysis progressive web app by browsing to http://graphicalanalysis.app.

The installed Chrome Web App can be directly accessed via The Chrome Store. Browsing to the store page on an up-to-date Chromebook you will see an install, update or open button for the app, but if your Chromebook is running ChromeOS 107 or earlier you will see this message:

Chromebooks with ChromeOS 107 and earlier that already have Graphical Analysis 5.17.2 or earlier can continue to use the installed application, but no updates will be available.

Chromebooks with ChromeOS 107 and earlier that do not have Graphical Analysis installed cannot obtain Graphical Analysis from the Web Store from the standard location, but a different version is available below.

If at all possible, update ChromeOS. If you cannot update ChromeOS, you will not be able to install Graphical Analysis from this page in the Chrome Web Store. Chromebooks are designed around the concept of frequent and easy updates. Google issues updates to Chrome OS most months, and updates are most often performed without user action when the device is rebooted.

To update, go to Settings and choose About Chrome OS. (Click the clock area of the shelf, choose Settings, and then About Chrome OS.) Choose Check for and apply updates to do this, and let the update download and install. Restart and return to the Chrome Web Store to load Graphical Analysis.

A terminal version of Graphical Analysis is temporarily available for older Chromebooks that cannot be updated. This version of Graphical Analysis will not receive any updates.

Note that Chromebooks have a design-limited life span in that updates to Chrome OS cease after a predetermined time relative to that model’s introduction date, not the purchase date. That duration can range from 5 to 8 years for Chromebooks generally available for purchase. If you purchase a model of Chromebook that was first introduced years ago, the duration will be shorter than 5 to 8 years. Google documentation refers to this date as the “Auto Update Expiration (AUE)”. Knowing the AUE of a Chromebook is a key purchase consideration, since a Chromebook with an AUE only a few years away will be quickly obsolete.

If your Chromebook is managed by an administrator, the maximum version of Chrome OS might be limited. However, Google strongly discourages the blocking of updates, and only supports the current version of Chrome for use with Google cloud services. Chromebooks that are not fully updated thus may not work as expected in the general ChromeOS/Google cloud environment.

Why does Graphical Analysis display a blank white screen on my Chromebook?
I need an older version of Graphical Analysis, Spectral Analysis, or Instrumental Analysis.
Should I use the Progressive Web App or native version of Graphical Analysis and other apps?
