Bar chart

[Spip]

Hello,

I am trying to create a bar chart. I have to put several colors, one for the first bars, and other colors for next bars, etc.
To do that, I put as many series as there are colors, but the problem is that the bars are not aligned with the scale on the horizontal axe.
I am wondering if it is possible to set several successive colors for one serie.
Has anybody something to propose to solve it ?

Thanks a lot in anticipation.

I think not, but I am interested.

I think u can it, just try some method in renderer to set colors.

[Spip]

I just extended BarRenderer class.

In calculateBarWidth and calculateBarW0 methods, I replaced dataset.getRowCount() by one.

Then, you have just to set one serie by bar, and one color by serie.

It is not very powerful, but it works.

Extend BarRenderer and override drawItem. Set color for each item before calling super.drawItem.

here is my code for it:

Code: Select all

class BarCategoryRenderer extends BarRenderer { 


	Paint paintArray[][]; 

	  public Paint getItemPaint(int column, int row) { 
		return paintArray[row][column]; 
	  } 

	  public void setItemPaint(Paint paint, int row, int column) { 
		paintArray[row][column]=paint; 
	  } 

	  public void setPaintListSize(int rowCount, int columnCount,Paint defaultPaint) { 
		paintArray = new Paint[rowCount][columnCount]; 
		for(int row=0; row<rowCount; row++) { 
		  for(int col=0; col<columnCount; col++) { 
			paintArray[row][col]=defaultPaint; 
		  } 
		} 
	  } 

	  public void setSeriesPaints(int QCol,int QLin,Cores cor) { 
		paintArray = new Paint[QLin][QCol]; 
		Paint paint1[];	
		for(int row=0; row<QLin; row++) { 
		  for(int col=0; col<QCol; col++) { 
			paint1 = new Paint[]{ cor.PegaCor(cor.CoresAUsar[QCol][col+1]) };
			paintArray[row][col]=paint1[0]; 
		  } 
		} 
	  } 
}
