> <IUCard title="Indirect Tag History Binding" link="https://inductiveuniversity.com/video/indirect-tag-history-binding/7.9" />

You can use indirection to configure the tag history binding to point to a set of tags based on any parameter on the screen.

## Set indirection on Tag History binding
1. Drag a **Table** (or a Power Table) from the Component Palette into your window.
2. In the Property Editor, go to the **Data** property, and click the binding icon.
The Property Binding window is displayed. 
3. Select the **Tag History** option.
4. From **Available Historical Tags**, find the desired historical tags by selecting and expanding the historical providers.
5. Once you have found the tag, drag it into to the right into **Selected Historical Tags**.
6. Open the **Indirection** box by clicking the plus sign next to it.
7. Double-click on one of the tags and enter a `{**1**}` in the part of the tag path that you want to create the indirection on. A new reference will appear in the indirection box. Bind the variable to the location.
8. Enter a desired start and end date in the **Start Date Binding** or **End Date Binding** text boxes.
A better option is to bind these to the date properties of date components.
9. Select the appropriate **Aggregation Mode**.
10. For **Sample Size**, select the **Interval** option from the drop-down, and enter the desired interval spacing.
11. Set **Polling Mode** to **Relative** to see table update at the project's base rate. 
12. Click **OK**.
