To style more than one series you need one ChartSeriesStyling addon per series and point each addon to the correct SeriesName.

1. Drag multiple ChartSeriesStyling addons

In the chart’s content:

1. Drag Addons\ChartSeriesStyling into the chart area.
2. Repeat for each series you want to style (e.g., HPPSeries, STLSeries, PriceSeries, etc.).

You will see multiple ChartSeriesStyling blocks in the widget tree under the chart, one per series.

2. Configure each addon for a specific series

For each ChartSeriesStyling instance:

• SeriesName: set to the exact name of the Data Series (the same value you use in DataSeriesName in the chart’s data points).
  • Example:
    • First styling block → SeriesName = HPPSeries
    • Second styling block → SeriesName = STLSeries
• SeriesType: if needed, set the type (Line, Area, Column, etc.) to override the default.
• FillColor: set the color for that series (e.g., "#FF0000" for red, "#0000FF" for blue).
• BorderColor / Marker / HideMarker: configure these if you want custom borders or markers for that series.

Each ChartSeriesStyling block only affects the series whose SeriesName matches, so you must create and configure one for each series you want to style.

3. Common pitfalls

• If all series show the same color, check that each SeriesName is different and correctly spelled, and that you’re not assigning colors at the data point level (which can override series colors and cause mismatches). OutSystems ColumnChart DataSeriesFormat not correctly displayed

If you share how many series you have and their names, I can suggest a concrete property setup for each one.
