Hi , i'am a newbie of Fusion Chart . I think it is a good product. I use powercharts with jquery var myChart = new FusionCharts("resources/grafici/powercharts/Charts/SelectScatter.swf", "SelectChart", "550", "400", "1"); myChart.setXMLData(datixml ); myChart.render("chartdiv"); I create a dinamic dataset and all is good if I use positive value in dataset while I obtain ERROR: Invalid number -115644 specified in XML. FusionCharts can accept number in pure numerical form only. If your number formatting (thousand and decimal separator) is different, please specify so in XML. Also, do not add any currency symbols or other signs to the numbers. with negative number. How could I use negative number (in data set )on select scatter chart ? Below the case with positive value in dataset on which I have no problem : <chart palette="3" caption="Test grafico" subcaption="Qui e' possibile inserire una descrizione" yAxisName="asse Y - Valori " xAxisName="asse X - Pesi" showLegend="1" showNames="1" xAxisMaxValue="1" yAxisMinValue="-500000" showValues="1" > <categories verticalLineThickness="0.1"> <category name="0.1" x="0.1" showVerticalLine="1"/> <category name="0.2" x="0.2" showVerticalLine="1"/> <category name="0.3" x="0.3" showVerticalLine="1"/> <category name="0.4" x="0.4" showVerticalLine="1"/> <category name="0.5" x="0.5" showVerticalLine="1"/> <category name="0.6" x="0.6" showVerticalLine="1"/> <category name="0.7" x="0.7" showVerticalLine="1"/> <category name="0.8" x="0.8" showVerticalLine="1"/> <category name="0.9" x="0.9" showVerticalLine="1"/> <category name="1" x="1" showVerticalLine="0"/> </categories> <dataSet id="PS" seriesName="Alternative" color="0372AB" plotBorderThickness="0" showPlotBorder="1" anchorSides="3" ><set id="INVEQ324_1" x="0.0" y="446931" tooltext="incrocio: 0.0, 446931 alternativa=3" /> <set id="INVEQ324_2" x="0.0" y="446931" tooltext="incrocio: 0.0, 446931 alternativa=3" /> <set id="INVEQ324_3" x="0.0" y="370638" tooltext="incrocio: 0.0, 370638 alternativa=2" /> <set id="INVEQ324_4" x="0.2" y="446931" tooltext="incrocio: 0.2, 446931 alternativa=3" /> <set id="INVEQ324_5" x="0.2" y="370638" tooltext="incrocio: 0.2, 370638 alternativa=2" /> <set id="INVEQ324_6" x="0.4" y="370638" tooltext="incrocio: 0.4, 370638 alternativa=2" /> <set id="INVEQ324_7" x="0.0" y="446931" tooltext="incrocio: 0.0, 446931 alternativa=3" /> <set id="INVEQ324_8" x="0.0" y="370638" tooltext="incrocio: 0.0, 370638 alternativa=2" /> <set id="INVEQ324_9" x="0.2" y="370638" tooltext="incrocio: 0.2, 370638 alternativa=2" /> <set id="INVEQ324_10" x="0.0" y="370638" tooltext="incrocio: 0.0, 370638 alternativa=2" /> </dataSet> </chart> Below the xml data with negative value on which I have the error: <chart palette="3" caption="Test grafico" subcaption="Qui e' possibile inserire una descrizione" yAxisName="asse Y - Valori " xAxisName="asse X - Pesi" showLegend="1" showNames="1" xAxisMaxValue="1" yAxisMinValue="-500000" showValues="1" > <categories verticalLineThickness="0.1"> <category name="0.1" x="0.1" showVerticalLine="1"/> <category name="0.2" x="0.2" showVerticalLine="1"/> <category name="0.3" x="0.3" showVerticalLine="1"/> <category name="0.4" x="0.4" showVerticalLine="1"/> <category name="0.5" x="0.5" showVerticalLine="1"/> <category name="0.6" x="0.6" showVerticalLine="1"/> <category name="0.7" x="0.7" showVerticalLine="1"/> <category name="0.8" x="0.8" showVerticalLine="1"/> <category name="0.9" x="0.9" showVerticalLine="1"/> <category name="1" x="1" showVerticalLine="0"/> </categories> <dataSet id="PS" seriesName="Alternative" color="0372AB" plotBorderThickness="0" showPlotBorder="1" anchorSides="3" ><set id="INVEQ324_1" x="0.0" y="-77794 " tooltext="incrocio: 0.0, -77794 alternativa=3" /> <set id="INVEQ324_2" x="0.0" y="-77794 " tooltext="incrocio: 0.0, -77794 alternativa=3" /> <set id="INVEQ324_3" x="0.0" y="-115644 " tooltext="incrocio: 0.0, -115644 alternativa=2" /> <set id="INVEQ324_4" x="0.2" y="-77794 " tooltext="incrocio: 0.2, -77794 alternativa=3" /> <set id="INVEQ324_5" x="0.2" y="-115644 " tooltext="incrocio: 0.2, -115644 alternativa=2" /> <set id="INVEQ324_6" x="0.4" y="-115644 " tooltext="incrocio: 0.4, -115644 alternativa=2" /> <set id="INVEQ324_7" x="0.0" y="-77794 " tooltext="incrocio: 0.0, -77794 alternativa=3" /> <set id="INVEQ324_8" x="0.0" y="-115644 " tooltext="incrocio: 0.0, -115644 alternativa=2" /> <set id="INVEQ324_9" x="0.2" y="-115644 " tooltext="incrocio: 0.2, -115644 alternativa=2" /> <set id="INVEQ324_10" x="0.0" y="-115644 " tooltext="incrocio: 0.0, -115644 alternativa=2" /> </dataSet> </chart> Thank in advance(I have search in forum but I don't have seen about this problem) Giorgio

Thank you thank you very much : it is that displayValue that I forgot. if it could be useful I have tried the example on the page without trend lines as follow : var datastring ='<chart palette="3" numberPrefix="$" is3D="1" xAxisMaxValue="100" showPlotBorder="0" xAxisName="Stickiness"\n\ yAxisName="Cost Per Service" chartRightMargin="30" showValues= "1">\n\ <categories>\n\ <category label="0%" x= "0"/>\n\ <category label="20%" x="20" showVerticalLine="1"/>\n\ <category label="40%" x="40" showVerticalLine="1"/>\n\ <category label="60%" x="60" showVerticalLine="1"/>\n\ <category label="80%" x="80" showVerticalLine="1"/>\n\ <category label="100%" x="100" showVerticalLine="1"/>\n\ </categories>\n\ <dataSet >\n\ <set x="30" y="1.3" z="1" name="Traders" />\n\ <set x="32" y="3.5" z="1" name="Farmers"/>\n\ <set x="8" y="2.1" z="1" name="Individuals"/>\n\ <set x="62" y="2.5" z="1" name="Medium Business Houses"/>\n\ <set x="78" y="2.3" z="1" name="Corporate Group A"/>\n\ <set x="75" y="1.4" z="1" name="Corporate Group C"/>\n\ <set x="68" y="3.7" z="1" name="HNW Individuals"/>\n\ <set x="50" y="2.1" z="1" name="Small Business Houses"/>\n\ </dataSet>\n\ </chart>\n'; and I have seen that dimension of bubble under some dimension don't resize that is z=100 or z=1 is the same if the size of bubbles is the same for all: is it correct ? Thank you again Giorgio

Thank you very much now goes . If I can I'd like to ask another thing about scatter and bubble chart. From examples (http://docs.fusioncharts.com/charts/contents/index.html?AttDesc/BubbleScatter.html ) I see that it is possible put labels on bubble but if I do in javascript : var datastring ='<chart caption="Portfolio of Investments in Equity" subcaption="(diameter of bubble indicates quantity of equities held) "\n\ xAxisName="Acquisition Price" yAxisName="Current Price" showValues="1" >\n\ <categories>\n\ <category x="0" />\n\ <category label="$20" x="20" />\n\ <category label="$40" x="40" />\n\ <category label="$60" x="60" />\n\ <category label="$80" x="80" />\n\ <category label="$100" x="100" />\n\ <category x="120" />\n\ </categories>\n\ <dataset>\n\ <set x="7" y="30" z="1000" name="A" />\n\ <set x="45" y="100" z="1500" name="B" />\n\ <set x="72" y="100" z="500" name="C" />\n\ <set x="95" y="40" z="800" name="D" />\n\ <set x="105" y="150" z="900" name="E" />\n\ <set x="25" y="35" z="600" name="F" />\n\ <set x="15" y="50" z="800" name="G" />\n\ </dataset>\n\ </chart>\n'; var myChart = new FusionCharts("SelectScatter", "SelectChart", "550", "400", "1"); myChart.setXMLData(datastring ); myChart.render("chartdiv"); I obtain/see value and not name and not bubbles but triangles. What I mistake ? Thank in advance Giorgio
