Data

Y plots against the nearest X to its left

Paste a block from a spreadsheet into any cell. A heading row such as L / m becomes names and units.

Formula column

Columns: choose one to add it to the formula.

Use * to multiply and ^ for powers. Functions include sqrt, log (natural), log10, exp, sin and mean.

Clear sheet

Choose what to clear. Nothing changes until you pick one.

Fill column

Mean of repeats

Tick the columns of repeat readings. A new formula column holds their mean, row by row; a row with a blank reading stays blank.

Repeat readings

View Table

Each value is shown with its own ± uncertainty. Copy the table into a spreadsheet, a document or a report.

Import CSV

Choose a role for each column. Nothing is guessed silently: check the suggestions before importing.
