 ## Build custom charts
 
-In the [Add legends](/developers/carto-vl/guides/add-legends/) guide, you saw how to add legends to a map using the [`getLegendsData`](/developers/carto-vl/reference/#expressionsrampgetlegenddata) method, and how to display widgets using histogram expressions in the [Add widgets](/developers/carto-vl/guides/add-widgets/) guide. In this guide, you will build upon those concepts and learn how to obtain and display information in custom charts using the `viewportHistogram` and `sampleHistogram` expressions and an external charting library.

 ### Histogram expressions
 
-CARTO VL has two expressions to create histograms: [`viewportHistogram`](/developers/carto-vl/reference/#cartoexpressionsviewporthistogram) and [`sampleHistogram`](/developers/carto-vl/reference/#cartoexpressionssamplehistogram). Both expressions return a list of values grouped by a column but differ in the way values are grouped. The `viewportHistogram` expression returns a list based off of features that are in the viewport, while the `sampleHistogram` expression returns a list based on a data sample.

-The map below combines both `viewportHistogram` and `sampleHistogram` expressions to compare the information returned for viewport vs sample feature calculations. If you interact with the map, you'll see how the bars for `sampleHistogram` remain static, while the ones for `viewportHistogram` change depending on the features present in the viewport.

-What you may notice is that if you zoom out, the `viewportHistogram` chart doesn't match the `sampleHistogram` chart. This is because the data returned for the `sampleHistogram`, as indicated by its name, is a **representative sample** of the data. Therefore, the results may vary since we're comparing the viewport data with a representative sample of the whole dataset.
