# Trend Analysis

> View revenue and expense trend charts over time for financial analysis in the Finance & Revenue core.

The Trend Analysis page (`/fa/analytics/trends`) displays revenue and expense trend charts over time for the current organization.

## Overview

The Trend Analysis page fetches trend data via `useFinancialTrends` (keyed by `organizationId`) and renders two chart components:

* `RevenueTrendChart`: Revenue trends over time.
* `ExpenseTrendChart`: Expense trends over time.

Both charts receive the full `trends` array and an `isLoading: false` prop. The page shows skeleton placeholders while loading and an error card on failure.

## Who it's for

Requires permission: `fa.analytics.trends.view`.

## Before you start

* You need `fa.analytics.trends.view` to access this page.

## Steps

**View trend analysis**
