Lightdash allows you to embed your dashboards using expirable URLs and tokens (embed URLs from now on). This is a great way to enable self-serve analytics in your own application and platform by leveraging the insights you've got in Lightdash and making them available to your own users.

Introduction

Lightdash API

Welcome to Lightdash! We're going to try to get you developing, exploring or just browsing your data in no time.

Getting started

This tutorial is for people who are new to Lightdash and would like to learn how to set up a new project. We'll show you how to get your dbt project Lightdash-ready, how to explore your data in Lightdash, and how to add metrics to your project.

Setting up a new project

Create your first project in Lightdash

Update your project connection

An intro to metrics and dimensions

Now that you've connected your dbt project to Lightdash, it's time to start exploring your data.

The Lightdash CLI is the recommended way to develop your dbt + Lightdash project. It makes development faster and easier, as well as giving you options for building more powerful automation to manage your Lightdash instance. Here are some guides to get you started!

Upgrading your Lightdash CLI

The beauty of Lightdash is that we're pretty well synced with your dbt project. So, in Lightdash, Tables actually come from dbt models that have been defined in your dbt project's `.yml` files.

Autogenerate Lightdash-ready .yml files for your models

Preview projects are temporary Lightdash projects where you can safely experiment with your metrics, dimensions and charts without affecting your production project.

Lightdash Preview

Sync your changes with Lightdash deploy

If you've connected Lightdash to GitHub, you can setup a `github action` and get Lightdash to compile your project and test your changes whenever you open a pull request.

Test your changes with Lightdash compile

You can check to see if your changes break any of the content in your project using `lightdash validate`. This command will run the validator which will return a list of content in your project that is broken and details about the errors.

Lightdash Validate

Using Filters

Use our SQL templates to get started with your table calculations!

SQL templates

The percent change gives you the percent change in a value compared to the value in the row above it.

Percent change from previous

Percent of previous value

The percent of the column total will give you the percentage of each value in the column out of the total sum of the values in the column.

Percent of column total

The percent of the group/pivot total will give you the percentage of each value in a group out of the total sum of the values for that group.

Percent of group/pivot total

Ranking values in a column is when you set every value as a number either higher than or lower than the other values. The lowest value (rank = 1) indicates the value with the first rank in your set of values.

Rank in column

Running totals give you the sum of a value + all of the previous values in that column.

Running total

Rolling windows, or lookbacks, calculate metrics like rolling averages using the current row combined with N previous rows. This can be useful for smoothing out volatile time series data to better understand long term trends.

Scheduled deliveries let you send a dashboard or saved chart, and their results to people via email or Slack - even to people who don't have an account in your Lightdash instance.

Scheduled deliveries

Alerts enable you to receive notifications via email or Slack when the value of a saved chart meets your specified conditions.

How to set up Lightdash YAML validation for VS Code

You can roll back to previous versions of charts in Lightdash. In case you make a mistake or simply want to go back to a previous version of a chart you built, you can easily revert back to previous versions of your charts. It's a great way to keep track of changes and revert back to previous versions if needed.

Chart Version History

With Lightdash, you can have a single organization (e.g. Lightdash), and multiple projects within that organization (e.g. Production, Jaffle Shop, etc.)

Creating multiple projects

You can update the default colours used in your organization's charts so that everything you build is on brand.

Customizing the appearance of your project

Promoting content enables you to copy content from one project to another. It's especially useful when working with preview or development projects. You can promote charts created in your development projects to production, so it's easy to test and make changes without the fear of breaking things in production.

How to promote content

Spotlight is a suite of features designed to put Metrics front and center. It simplifies data exploration, making it easy for business users to focus on metrics without dealing with complex tables or time dimensions.

Dimensions are the columns in your table. They are the "attributes" of your data. For example, `user_id` in your users table is a dimension.

Joins let you connect different models to each other so that you can explore more than one model at the same time in Lightdash and see how different parts of your data relate to each other.

Broken content is not useful content. We've built tools in Lightdash to help validate your content so you can keep it useful and we'll notify you when it isn't.

Validator

Validating your content

dbt Write-Back allows you to develop your models and Metrics in Lightdash and write back these changes to your dbt project. Writing back to dbt will create a new branch and pull request in your project so you can save and manage these changes.

dbt Write-Back

You can download your charts and dashboards as code, make changes, then upload your changes back to your Lightdash project using the CLI. Content as code is also useful for creating new Lightdash projects where you want the content to be copied from an existing project and added to your new project.

Dashboards as code

When writing SQL in your Lightdash models, you can use the following references to template you SQL and make it more reusable

Caching can reduce the overall number of queries that Lightdash executes against your data warehouse. Learn more about the types of caching and how to enable caching in this doc.

Below are detailed reference docs for all the ways you can explore and visualize data in Lightdash.

Data Exploration Reference Docs

Results tables can be useful for finding specific numbers or checking out your data, but it's usually easier to see trends and make sense of your data using charts.

Chart types

Custom charts are available in Beta for those that want additional customization and an extended library of charts.  The charts are powered by [vega-lite](https://vega.github.io/vega-lite/examples/) - the link will take you to some example galleries of what you can build using this powerful charting library.  This includes heat maps, bubble plots, box plots and more.

Custom Charts

Filters appear at the top of the Explore view and allow users to change the data being pulled in.

Filters reference

The fields that you see in your `dimensions` and `metrics` are created by the people maintaining your Lightdash project. But, you can create new custom dimensions or metrics for quick calculations and binning on the fly. On this page, we'll explain what custom dimensions and metrics are and how to use them.

Using custom fields

Table calculations make it easy to create metrics on the fly (for example, aggregating the data in your table over some window, or getting a running total of a column).

Table Calculations

Once you've used Lightdash for a while, your team will probably end up with a lot of saved charts and dashboards. Spaces let you organize your saved charts and dashboards.

Roles and permissions

Groups are a way to manage access to multiple users at the same time. A user can belong to multiple groups.

Groups

User attributes provide a way to customise Lightdash charts, dashboards, and other behaviour depending on the user that is logged in. For example, you could only show your sales team members data that are relevant to their region.

The recommended resource requests for each Lightdash component are as follows

Resource recommendations

To run Lightdash in production it is highly recommended to secure it with HTTPS. This is usually done using your cloud provider's load balancer or ingress controller. Optionally you could use a proxy service like \[nginx\]([https://www.nginx.com/](https://www.nginx.com/)) or [traefik](https://traefik.io/).
