Quick way to draw path and test data

There's probably a better way to do this, but...

Wanted to test my math on a formula I used to create custom data series. Didn't want to bother with setting up RuntimeDescriptors, etc. So created this func.

It will draw a small, colored circle for each bar of data (your eyes can connect them into a path). 'dataKey' refers to either the string key for a custom data series, i.e.: "SMA50", or an enum. It's got the 'Object' or 'Any' type, so be careful to only pass it a String or an Enum. The other args should be self-explanatory.

Call it from within the 'calculate()' func in your study/strat.

Java version


void drawUglyPath(DataSeries series, int index, Object dataKey, Color color) {
   if (series.getDouble(index, dataKey) == null) {
      return;
   }

   Enums.Position position = Enums.Position.TOP;
   Double seriesValue = series.getDouble(index, dataKey);

  MarkerInfo mInfo = new MarkerInfo(Enums.MarkerType.CIRCLE, Enums.Size.VERY_SMALL, color, color, true);
     addFigure(
       new Marker(
          new Coordinate(series.getStartTime(index), seriesValue),
                  position,
                  mInfo
                ));
}

Kotlin version


fun drawUglyPath(series: DataSeries, index: Int, dataKey : Any, color: Color) {
    if (series.getDouble(index, dataKey) == null)
       return

    val position = Enums.Position.TOP
    val seriesValue = series.getDouble(index, dataKey)

    val mInfo = MarkerInfo(Enums.MarkerType.CIRCLE, Enums.Size.VERY_SMALL, color, color, true)
        addFigure(
            Marker(
               Coordinate(series.getStartTime(index), seriesValue),
                  position,
                  mInfo
            )
    )
}
