# Set Tier for Timescale

## Content



In GanttView, timescale is represented by the **Timescale** class which is accessible through the **Timescale** property of the **Task** class. You can use the **Timescale** property to set tier for timescale to Top Tier, Bottom Tier or Middle Tier. In addition to, you can also set the format and units for the timescale using the Format and Units property of the **ScaleTier** class. The **Units** property takes the **TimescaleUnits** enumeration to set the unit of timescale.

Below code snippet shows how you can set tier for timescale in the GanttView.

```csharp
ScaleTier st1 = c1GanttView1.Timescale.TopTier;
    st1.Units = TimescaleUnits.ThirdsOfMonths;
    st1.Format = "sd";
    st1.Visible = true;
```
