# Metric charts

> Build charts from Sayless metric data, compare account activity across companies, and configure visualizations for reports and dashboards.

Metric charts turn event data into visual views your team can review.

## Overview

Open a metric chart when you want to understand trends, totals, distribution, or company-level comparisons.

Metric charts use the same general chart control patterns as reports: choose a data shape, configure axes, select aggregation, choose intervals, and compare companies where relevant.

Open a chart from a metric detail page or use the route pattern `https://joinsayless.com/{workspace}/metrics/{metricName}/chart`.

| Control          | What it changes                   |
| ---------------- | --------------------------------- |
| Chart type       | The visualization format.         |
| Aggregation      | How event values are summarized.  |
| Interval         | How time-based data is grouped.   |
| Axis controls    | Which fields appear on the chart. |
| Company selector | Which companies are included.     |
| Sort             | How chart results are ordered.    |

## Build a chart

Chart controls let you shape the visualization.

### Chart type

Choose the chart format that fits the question.

Changing the chart type changes which controls matter. A single-value chart needs different context than a line chart or table chart.

### Aggregation

Aggregation controls how event values are summarized.

Use aggregation when multiple events need to become one value, such as count, sum, or another summary operation supported by the chart.

### Interval

Interval controls how data is grouped over time.

Use shorter intervals for recent operational work and longer intervals for trend review.

### Axis controls

Axis controls define which fields appear on the chart.

If the chart looks empty, confirm the selected fields exist in the metric events.

## Chart types

Available chart types include common formats used throughout the metrics and reports areas.

### Line chart

Use line charts for trends over time.

### Bar chart

Use bar charts for comparing grouped values.

### Pie chart

Use pie charts for part-to-whole breakdowns.

### Table chart

Use table charts when exact rows matter more than a visual summary.

### Single value

Use single-value charts for one important number.

## Compare data

Use comparison controls when company context matters.

### Company selector

Select companies to include in the chart.

### Company comparison

Compare companies against each other.

Company comparison works best when events are consistently linked to companies.

### Sorting

Sort chart results when order changes the interpretation.

## Troubleshooting charts

Most chart issues come from missing data, incompatible chart settings, or fields that do not exist on the event data.

### Empty chart

Check that the metric has events, that the selected interval includes data, and that the chosen fields exist.

> If a chart is empty but the metric has events, inspect [Metrics > Events](https://joinsayless.com/\{workspace}/metrics/events) to confirm the event fields match the chart controls.

### Unexpected values

Review aggregation and axis settings first. Then inspect raw metric events to confirm the source data.

### Company comparison gaps

If a company is missing from comparison, confirm the metric events are associated with that company.
