livechart设置axis出现错误

遇到一个livecharts使用的问题，就是我设置他的时候他会出现一个错误
LiveChartsException: One axis has an invalid range, it is or it tends to zero, please ensure your axis has a valid range
就是这样的报错
下面我附上我的设置
希望大家能帮助解决一下

 <lvc:CartesianChart  Series="{Binding LineSeriesCollection}"  LegendLocation="Left"  Margin="0,50,0,0" >
                                    <lvc:CartesianChart.AxisX>
                                        <lvc:Axis  Labels="{Binding Labels}"  >
                                            <lvc:Axis.Separator>
                                                <lvc:Separator Step="1" />
                                            lvc:Axis.Separator>
                                        lvc:Axis>
                                    lvc:CartesianChart.AxisX>
                                    <lvc:CartesianChart.AxisY>
                                        <lvc:Axis LabelFormatter="{Binding CustomFormatterY}" MaxValue="{Binding AxisYMax}" MinValue="{Binding AxisYMin}">
                                        lvc:Axis>
                                    lvc:CartesianChart.AxisY>
                                lvc:CartesianChart> 

单片机是什么啊？
