# Transparency Slider
### Controlling Color Opacity with the Transparency Slider :
In Version 5.1, a new slider has been introduced that allows users to adjust the transparency of a specific color applied to regions where color opacity can be customized as required. This feature is available in the Thresholds, Appearance, Subtotals, Format, Tooltip, and Grand Totals tabs.
Below is a sample GIF demonstrating how to use the transparency slider. By adjusting the transparency, a value in the chart can be hidden.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.vitaracharts.com/grid-microchart-guide/transparency-slider.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
