You can go into Power Query Editor:

<a href="https://i.stack.imgur.com/A2Vmt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/A2Vmt.png" alt="Power BI edit queries"></a>

And you will need to add a new column for each datasheet with the legend you want, for example:

<a href="https://i.stack.imgur.com/DXXIM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DXXIM.png" alt="Power BI add custom column"></a>

So your tables should look like this:

<a href="https://i.stack.imgur.com/DQv8Q.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DQv8Q.png" alt="Power BI query"></a>

<a href="https://i.stack.imgur.com/bHsjg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bHsjg.png" alt="Power BI query"></a>

Then merge the tables with Append Queries as New:

<a href="https://i.stack.imgur.com/zGwOh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zGwOh.png" alt="Power BI Append Queries as New"></a>

Select Three or more tables, and add the three tables:

<a href="https://i.stack.imgur.com/PSNQr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PSNQr.png" alt="Power BI Three or more tables"></a>

And there you have your three tables merged into one.

<a href="https://i.stack.imgur.com/VfPLW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VfPLW.png" alt="Power BI Stacked Column Chart"></a>

<h2>Input</h2>

I have three datasets (simplified example below):

<ul>
<li>List of students from school A and their age (1200 records)</li>
<li>List of students from school B and their age (200 records)</li>
<li>List of students from school C and their age (2000 records)</li>
</ul>

Every dataset has two columns: <code>studentId</code> and <code>age</code>.

<h2>Desired result</h2>

I want to create a bar chart that shows the distribution of age across these schools. For easy comparison I would like to have:

<ul>
<li>one bar chart</li>
<li>with three legend entries: 

<ul>
<li>A </li>
<li>B </li>
<li>C </li>
</ul></li>
<li>7 categories:

<ul>
<li>age =&lt; 12 </li>
<li>age = 13 </li>
<li>... </li>
<li>age >= 18 </li>
</ul></li>
</ul>

<h2>What I have tried</h2>

I tried linking the datasets, but due to the different number of students and the various <code>studentId</code> formats per school this did not work.

I tried using the <code>studentId</code> columns of the three datasets as the value and the <code>age</code> column of every dataset as the axis. This only worked one dataset at a time. I needed to "Go to the next level in the hierarchy" to see the other dataset.

How else can I achieve this?

How do I create a single bar chart from three independent data sources?
