Steps

First start off by opening up your Graphics Builder
Drag and drop Ractive into the workspace from your components menu on the left side
Add a tag on your Ractive model. For our example we are using vpQuery
Next on the left side menu open Programs and click the + icon at the bottom left to add a new program
Under Program Name, name your program whatever you would like, for this example we are calling it getData
Under Program Target Filter, type in the name of the tag you set on your Ractive model, in our cause this would be vpQuery
Next click the three dots in the top right corner and select Variables
Click the + icon next to Program Vars
Notice how New Variable appeared, as you scroll over it a gear icon will appear, click on it to edit the new variable
There should be two lines. On the top line type point and on the second line type id==$virtualPointRef
Under the second line turn on Invokes the function and a third text box should appear
Select Tag Change from the dropdown menu and under type in curVal and click the gray save button
Then in the main section of your code copy and paste this.value = point; and select the blue save button
Now go back to your ractive model, click on it in the workspace and under properties on the left side menu open up the Ractive editor
This is where you can design your component, below is an example code
Copy and paste it under the Template section of the component and click save

{{#value}}
<div class="view-superman-value">
<label>{{idDis}}</label>
<br>
<label>{{navName}}: {{curVal}}{{unit}}</label>
</div>
{{/value}}

The first and last lines, {{#value}} and {{/value}} is what connects the data with the program.

Wherever there is {{ }} with a value inside, it is getting that value from the virtual point which will be dragged onto it

So in this example our model will show the id, navName, curVal and unit of the virtual point.

Next drag and drop a virtual point on top of your ractive component, from the virtual points menu on the left side.

Click preview and your done!
