# Irregular Stacked Chart Data

## Content



Stacked charts are charts that have one or more series stacked upon a base series. All of the Y values for the chart are taken as distances from the previous series' Y value. Stacked charts are a simple issue when data is loaded in an array format where the X values all match and all the series are stacked on top quite neatly.

[C1Chart](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.C1Chart.html) provides more freedom by allowing data to be in a General Layout. General Layout means that not all series must have identical X values. While this freedom allows for charting of more non-standard sets of data, it poses a problem when using stacked charts.
