Will PlotPeek answer
your question?

Choose what you need to understand, then inspect the relevant controls, outputs and limits without reading one long technical list.

Input formats · PlotPeek 1.2

Open the format you already have.

PlotPeek 1.2 opens CSV, Excel and Parquet directly, with worksheet, range and typed-column handling built into the same private on-device flow.

Available

CSV

Open familiar delimited data with robust date and separator handling.

Available in 1.2

Excel · .xlsx

Choose a worksheet or range before the analysis begins.

Available in 1.2

Parquet

Keep analytical column types without a conversion step.

Feature navigator

Start with the question.

Select a category or describe the result you need. PlotPeek shows only the modes that matter, with clear distinctions between purpose, controls and output.

Time & source

Follow change—or inspect the rows behind it.

Move between an ordered signal and the exact records that produced it.

01

What it helps you see

Time series

How did values change over time?

Track one or many numeric variables over time, compare files and isolate the period that matters.

Controls available
  • Choose time, value and repeated-series columns across active files
  • Resample from minutes to days; aggregate by mean, sum, min, max or RMS
  • Smooth with rolling mean/median, EMA or Gaussian windows
  • Set exact dates, recent ranges and a maximum plotted-point count
  • Rename axes and series; customise colours, line styles, widths and secondary axes
02

What it helps you see

RAW data

Which exact rows support the result?

Inspect the source table and verify the records behind a visual conclusion.

Controls available
  • Choose visible columns and sort rows without changing the source
  • Reuse category and numeric filters from analysis views
  • Preserve source identity when several files are active
  • Export filtered records as a new CSV
Import Workflow

Save the import.
Reuse the workflow.

A named recipe turns a familiar data file into a prepared PlotPeek view instead of rebuilding the same analysis every time.

Data files arriveChoose a saved workflowStart from a prepared view
01

Open the right analysis

Remember mode, time and value columns. Headers match exactly first, then case-insensitively; missing columns are skipped and reported.

02

Use only the rows you need

Keep all rows, first or last rows, or a custom one-based range for every file.

03

Prepare and style the signal

Reuse resampling, aggregation, smoothing, point limit, line type, width and a repeating colour palette.

04

Apply it where work begins

Use workflows after selecting files, in the Library or through Apple Shortcuts for automated import, processing and export.

Workflows are managed in PlotPeek Settings and sync across iPhone, iPad and Mac.

Across the workspace · through 1.1

Prepare once.
Explore many ways.

01

Bring the data

Open one or several files. PlotPeek handles separators, local and ISO dates, and preserves each source inside a combined view.

02

Filter the question

Keep selected categories and numeric ranges. Every mode recalculates from active filtered rows.

03

Organise the Library

Use Projects, folders, tags, search, saved selections, iCloud sync or a transient incognito workflow.

04

Write beside the result

Create Markdown Notes with folders, tags, search, attachments and Recently Deleted, then link notes and captures to graphs.

05

Keep a workspace alive

Use multiple views and graph panes, save named Sessions and recover interrupted work without replacing the current view.

06

Move faster

Open the Command Bar, customise keyboard shortcuts, or use Siri, Shortcuts and App Intents to repeat an import and export.

07

Make the view yours

Choose a theme, customise individual series and save mode-specific defaults for the next analysis.

08

Work on any screen

The same modes adapt to iPhone, iPad and Mac with touch, pointer and keyboard interactions.

Export options

Make the next step ready.

Export the evidence, the presentation-ready view or the exact filtered rows without rebuilding the work elsewhere.
