# View Data from Multiple Runs in Histogram

**Purpose:** Learn to load multiple runs in a [Histogram Chart](/v1/docs/histogram-chart) for comparison.

**Task:** Open a Histogram chart by launching it from a Trend. Use the Run Browser to retrieve data for a give period type over a relative time window of 10 to 15 days ago. Filter values as needed.

**Steps:**

1. To create a Histogram from a Trend, right-click the a tag in the tag grid and choose **Histogram**.

2. Expand the Run Browser by clicking on the panel to the left.

3. On the **Run Filter** tab, select **Multiple Runs for Process and Period** as the time period source. The Location / Process Period Type and Filter Runs By sections will appear. Also, the Location and Process fields are pre-populated based on the properties of the first tag in the Histogram. If the selected process is grade-based, the Grade Filter section will also appear.

4. Set the **Period Type** to the desired type of run.
5. If the selected process area is grade-based, set the **Grade Filter** as desired.
6. Set **Filter Runs By** to “Relative Time”. Set the **Start** time to “DAY-14D+7H” (case sensitive) and the **End** time to “DAY-1H” (case sensitive).

8. If necessary, use the **Min** and **Max** filter fields to exclude high and low values. Click **Plot** again after making changes.
