Hi All,

I want to change the color of some point inside a Chart component. I tried myself but I’m not so familiar with Java ( yet 😉 ).  
After a lot of Googleing around I know I have to determine which renderer class is being used ( `org.jfree.chart.renderer.xy.StandardXYItemRenderer` ) and create a subclass of it where override the getItemPaint() method to return a specific color for the data item that I wish to highlight, but I don’t know how to do it 😅  
Any help would be much much appreciated 🙂

Cheers,

---

Something like this should do the trick.

```auto
	from org.jfree.chart.renderer.xy import StandardXYItemRenderer
	from java.awt import Color
	
	class myXYItemRenderer(StandardXYItemRenderer):
		
		def getItemPaint(self,row,column):
			#whatever criteria you want to use to determine color
			if row == 0 and column >= 12:
				return Color.BLACK
			else:
				return StandardXYItemRenderer.getItemPaint(self,row,column)
				
	chart.getXYPlot().setRenderer(myXYItemRenderer())

```

Thanks!! 👍👍

For posterity:  
row is the series  
column is the item
