## Pen Names and Group Overview
You can organize pens on the Easy Chart by creating custom names and groups for each pen. By default, when you drag Tags from the Tag Browser on to the Easy Chart component, the pen name is the same as the Tag name and organized into a single group called ‘**Pens**.'  One of the great things about pens is you can change pen names and organize pens into different groups making it easier for the operator to quickly analyze the data.

### Configuring Pen Names and Groups
For each Tag on the Easy Chart, let's create unique pen names and organize each pen into a group using the Easy Chart Customizer. 

1. Right click on the Easy Chart component, and scroll down to **Customizers > Easy Chart Customizer**.  
 
2. On the **Pens** tab, edit each of the individual pens and give them a different name as well as put them inside a different group. 

    1. Select the first pen row, click the **Edit** ![](edit.png) icon, and rename the first Tag from **‘Ramp0’** to **‘R0’** as shown in the following example.  
    1. At the bottom of the Edit Pen window, next to **Group Name**, create a new group called ‘**Ramps.**’  
    1. If other groups exist, you can select one from the dropdown list or enter your own.  In this example, this is the first group to be created, so simply type ‘**Ramps,**’ and press **OK**. 

3. Repeat this step for each Ramp pen assigning each pen a new name.

4. Next, let's keep the Sine pen names the same as the Tag name, but add them to a group. 

    1. Select the **Sine0** pen row, and click the **Edit** ![](edit.png) icon.  
    1. Enter a new group name called '**Sines**'. 
    1. Click **OK**.
    1. Repeat this steps i and iii. to add each Sine pen to the Sines group.

4. Once you have all your pens configured, click **OK**. Operators will see the Pen and Group names organized into two legends on the Easy Chart.  You can update the pen and group names on this view by double clicking on any of the fields. It’s a faster way to edit this information then having to go to the Edit icon for each pen.
