# Analytics

> Explore spend over time, filter and group it by any dimension or attribution node, and export the result.

Analytics is where you go to answer a question the dashboards did not anticipate, why a line moved, which service drove it, how a node's spend splits. It charts spend over time and puts the numbers behind the chart in a table beneath it.

## Open Analytics

Under **Explore**, select **Analytics**. The page shows **Spend History** for the date range set at the top of the screen, with a table of the same figures underneath.

## Choose what to look at

Select **Filters** to open the filter panel. It has two tabs:

* **Spend**: filter raw billing data. Start with **For** to choose a provider, then **Add condition** to narrow further. Use **+ Add condition** below the group to add another group of conditions, and **Clear all filters** to start again.
* **Attribution**: scope the view to an attribution model and node.

Use **Group By** to split the chart by a dimension, such as service or account.

Under **More options**:

| Option | Choices | What it changes |
| :- | :- | :- |
| **Pricing** | **Gross**, **Net** | Whether credits and discounts are deducted |
| **Cost metric** | **Billed**, **Amortised**, **Contracted**, **List** | Which cost figure from the bill is used |
| **Allocations** | **Include allocations** | Whether [showback](https://docs.optimazehq.com/attribution/showbacks.md) amounts are included |

Select **Apply** to update the chart and table. Set **Granularity** to change the time bucket.

## Change the chart

| Chart | Best for |
| :- | :- |
| **Stacked bar chart** | Comparing totals and their make-up per period |
| **Line chart** | Trends over time |
| **Stacked area chart** | Share of total over time |
| **Heatmap** | Spotting patterns across many groups and periods |
| **Showback flows** | How cost moves from its source to attribution nodes |

Use **Colours** to change the palette.

## Work with the table

The table under the chart lists each group by period with a **Total** column. Search rows, add a filter to the table, change row density, and select **Export** to download the figures.

## Ask Atlas

Select **Atlas AI** at the top of the screen to ask a question about what you are looking at. Atlas opens with the page as context, see [Atlas](https://docs.optimazehq.com/atlas.md).
