Right-click any cell to access column-specific actions:
Set as x-axis — Sets the clicked column as the X-axis for graphing. The X-axis column is highlighted in a distinct color. Hidden if the column is already the X-axis.
Reset x-axis — Restores the default (leftmost) column as X-axis. Shown only when a custom X-axis is active and you right-click on it.
Show numerical differences — Replaces column values with row-to-row differences (value[k] − value[k−1]; first row is set to 0). Diff columns are highlighted in a distinct color. Hidden if the column is already in diff mode.
Show original values — Restores original data for a column in diff mode. Hidden if the column is already showing original values.
