# Pareto chart

{% hint style="info" %}
Available in a focused view (when you select and focus on items in a dimension), in Total mode only.

A Pareto chart shows the relative importance of differences between large sets of values. It shows cumulative totals of contributing factors to assess the success or failure metrics. It is often used for root cause analysis, in other words, to highlight the most significant cause of a certain outcome. It contains both columns and a line, with the columns representing individual values (in descending order) and the line representing the cumulative total.

<summary>Example 1: Use a Pareto chart to analyze sales revenue</summary>

In a Sales database, create a Pareto chart to see at a glance where the bulk of your revenue comes from.

1. Prepare the data in the grid: Select the **Customer** dimension, select **Mode** > **Total**, and select **Period** > **Financial YTD**.
2. Click the **Chart** button in the top right toolbar above the grid. The Bar chart type displays by default.
3. Click the **Bar** chart category button on the left of the chart and select the **Pareto** option.

   The columns display revenue for individual customers, while the pareto line charts the cumulative total. You can hover over a data point on the pareto line to view the entity name, cumulative value and cumulative percent of overall revenue.

<summary>Example 2: Use a Pareto chart to identify the cause of a decline in sales</summary>

As a Sales Executive, you have been alerted to a decline in sales over a three-month period. You want to find the major contributors to the decline, initially at a customer level and then drilling further into region or product information.

1. Prepare the data in the grid: Select the **Customer** dimension, then select and focus on the customers with sales of less than 200,000. Select **Mode** > **Total**, then select **Period** > **Financial YTD**.
2. Click the **Chart** button in the top right toolbar above the grid. The Bar chart type displays by default.
3. Click the **Bar** chart category button on the left of the chart and select the **Pareto** option. The columns display revenue for individual customers, while the pareto line charts the cumulative total. You can hover over a data point on the pareto line to view the entity name, cumulative value and cumulative percent of overall revenue. Now you have the customer overview, you can further slice and dice the data for a particular region, customer, product group or even product.
