# Chart drill-down

> Click any chart segment to see the records behind it.

Every report chart that groups records is **drillable**. Click a segment and Custral opens the exact records that segment represents. A "Companies by Status → Active" slice means *the companies whose status is Active*; a line point on a given day means *the records in that day's bucket*. It turns a chart from a picture into a way into your data.

## Drill into a chart

<Steps>
  <Step title="Click a segment">
    Click a pie slice, a bar, a point on a line or area, a scatter or bubble dot, a heatmap cell, or a funnel step.
  </Step>

  <Step title="Read the records behind it">
    A panel opens listing the records that make up that segment, with the same columns as the object's records table.
  </Step>

  <Step title="Open the full page">
    Choose **Open full page** for a full-screen, sortable table of the same records, useful when a segment holds more than a quick look.
  </Step>
</Steps>

The drilled list always matches the segment's count, because it applies **the chart's own filters and any dashboard filters**, the same rules that drew the chart.

## What you can drill

<CardGroup cols={2}>
  <Card title="Proportion charts" icon="chart-pie">
    Pie, donut, radial-bar, bars-list, and treemap. Click a slice or bar.
  </Card>

  <Card title="Series charts" icon="chart-line">
    Bar, area, line, and composite. Click a bar or point at an x-value.
  </Card>

  <Card title="Point & grid charts" icon="chart-scatter">
    Scatter and bubble dots, and heatmap cells.
  </Card>

  <Card title="Funnel" icon="filter">
    Click a step to see the records at that stage.
  </Card>
</CardGroup>

A few chart types aren't drillable by design: **radar** (each spoke is a different measure, not a value of one dimension), **sparkline** (a decorative trend), and the **stat / KPI card** (a single number, not a set of records).

## Troubleshooting

**Clicking a chart does nothing.**
That chart type isn't drillable, radar, sparkline, and stat cards have no per-element record set (see above). Every other chart drills.

**The drilled list is empty.**
The segment genuinely has no records, or a dashboard filter is excluding them. Check the chart's filters and any linked dashboard filters. The drill honors both.

**An "Unknown" slice drills to blank records.**
"Unknown" is the bucket for records with **no value** on that property. Drilling it lists exactly those empty-valued records, which is correct.
