# Analyze and compare

> What the Analysis tab is actually for, and how to build a comparison chart across experiments step by step.

Analysis is the project tab for **cross-experiment comparison** — putting Series and Figures from more than one experiment onto the same chart. If you've been opening individual experiments and wondering how to put two of them side by side, this is that feature.

## The mental model

<Steps>
  <Step title="Mark experiments as visible">
    From the **Experiments** list, mark up to 8 experiments as visible (the eye toggle) — this doesn't navigate you anywhere or change what you're looking at. It just adds that experiment's Series and Figures to the pool Analysis can draw from.

    <Note>
      This is deliberate: selecting/pinning an experiment never auto-jumps you into a comparison view. You explicitly open **Analysis** when you're ready to build a chart — the two actions are kept separate on purpose.
    </Note>
  </Step>

  <Step title="Open Analysis">
    The left-hand picker lists every Series and Figure available across your visible experiments.
  </Step>

  <Step title="Build a chart tile">
    * **Click** a series to select it (replacing whatever was in that tile)
    * **Ctrl/Cmd+click** to add it alongside what's already selected (multi-trace — e.g. overlay cellA1 and cellB1 on one chart)
    * **Alt+click** to set that series as the tile's X axis instead of Y

    </Frame>
  </Step>

  <Step title="Arrange tiles">
    Tiles are resizable and can hold multiple series or figures. Your arrangement is remembered per pipeline, so reopening Analysis later picks up where you left off.
  </Step>
</Steps>

## Series vs. Figures in Analysis

The same overlay rules from the [data model](/concepts/data-model) apply here: Series overlay freely with any other Series, Figures overlay panel-by-panel with another Figure of matching layout, and Series never mix with Figures in one tile.

## Comparing scalar values instead of curves

Analysis overlays Series and Figures — but sometimes what you want to compare is a Config or Summary value across many experiments at once, like capacity versus a design parameter. For that, the **Experiments** list has its own **Plot view** (next to Card and Table view): pick any Config or Summary column for the X and Y axis and it scatters every experiment in the current filter.

<Frame caption="Plot view on the Experiments list: capacity_mAh vs. cathode_thickness_um across all seven experiments, colored by Script — the five simulated designs (orange) trace a clean trend, and the two measured cells (blue) land close to their simulated counterparts.">

</Frame>

This is a quicker path than Analysis when the question is about logged values rather than the shape of a curve — no need to mark experiments visible first, since Plot view reads directly from whatever's currently filtered in the list.

## Jumping in from an experiment

Inside an experiment's **Images** tab, a Figure has a direct link into Analysis with that figure pre-selected — useful when you spot something interesting in one experiment and want to immediately see how it compares against others, without rebuilding the picker state from scratch.

## Turning a comparison into something you can share

An Analysis arrangement is working state — it's yours, live, and keeps changing as you explore. When you have something worth keeping or sending to someone, save it as a [Report](/guides/reports).
