[Time series is displaying each day twice on x axis]

Hi,

I have the same problem with time axis.

What should be the value of timePeriod to have only one point per date?

thanks for help

Code:

...<field name="date" class="java.sql.Timestamp"/>...<timeSeriesChart>                <chart>                    <reportElement x="0" y="15" width="611" height="240"/>                    <chartTitle/>                    <chartSubtitle/>                    <chartLegend/>                </chart>                <timeSeriesDataset timePeriod="Day">                    <timeSeries>                        <seriesExpression><![CDATA[$F{id}]]></seriesExpression>                        <timePeriodExpression><![CDATA[$F{date}]]></timePeriodExpression>                        <valueExpression><![CDATA[$F{value}]]></valueExpression>                        <labelExpression><![CDATA[$F{id}]]></labelExpression>                    </timeSeries>                </timeSeriesDataset>                <timeSeriesPlot>                    <plot/>                    <timeAxisFormat>                        <axisFormat>                            <labelFont/>                            <tickLabelFont/>                        </axisFormat>                    </timeAxisFormat>                    <valueAxisLabelExpression><![CDATA[dd.MM.YYYY]]></valueAxisLabelExpression>                    <valueAxisFormat>                        <axisFormat>                            <labelFont/>                            <tickLabelFont/>                        </axisFormat>                    </valueAxisFormat>                </timeSeriesPlot>            </timeSeriesChart>
