Re: [jCharts-users] Horizontal grid line problems

[Nathaniel G. A. <nat...@ya...>]

wow, look at that.

For some reason the code in org.jCharts.axisChart.axis.YAxis got commented out and other code
inserted in its place.  If you look at line 243 in YAxis you will see:

/*
if( i < super.getAxisLabelsGroup().size()
   || ( i == super.getAxisLabelsGroup().size() && !axisTypeProperties.getShowEndBorder() ) )
*/
if( i == super.getNumberOfScaleItems() - 1 && !axisTypeProperties.getShowEndBorder() )
{
  axisTypeProperties.getGridLineChartStroke().draw( graphics2D, line2D );
}
else
{
  //---draw top border with the same ChartStroke as the X-Axis
  axisProperties.getXAxisProperties().getAxisStroke().draw( graphics2D, line2D );
}



change the if so it is the commented out if statement.


if( i < super.getAxisLabelsGroup().size()
   || ( i == super.getAxisLabelsGroup().size() && !axisTypeProperties.getShowEndBorder() ) )
{
  axisTypeProperties.getGridLineChartStroke().draw( graphics2D, line2D );
}
else
{
  //---draw top border with the same ChartStroke as the X-Axis
  axisProperties.getXAxisProperties().getAxisStroke().draw( graphics2D, line2D );
}


this will work for you.

remember to set the:
axisProperties.getYAxisProperties().setShowEndBorder( false );

so your red grid lines are not drawn over the end of the axis.


Can you do a build locally or would you like a build from the site?  I guess we should do a build
as this is a hairy bug.
