Resolution

The lines, displayed in PDF output, are so-called divisional lines:

In order to remove/hide them in PDF, try to specify the following settings in 'Divisional Lines and Grids' menu of the chart settings:

Num = 0

Color = #FFFFFF

Alpha = 0

Please find attached printscreen:

It might be possible that the properties seem to be already set.

In that case try to change them to another value and then back to the provided one, to make sure the values are really saved,

or manually modify report JRXML file and add required properties:

<fc:chartProperty name="divLineColor">
    <fc:propertyExpression><![CDATA[new java.awt.Color(-1)]]></fc:propertyExpression>
</fc:chartProperty>
<fc:chartProperty name="numDivLines">
    <fc:propertyExpression><![CDATA[new Integer(0)]]></fc:propertyExpression>
</fc:chartProperty>
<fc:chartProperty name="divLineAlpha">
    <fc:propertyExpression><![CDATA[new Integer(0)]]></fc:propertyExpression>
</fc:chartProperty>
