Hi,

<vc:Chart x:Name="_chart" Width="500" Height="165" BorderBrush="Gray" BorderThickness=".5" IndicatorEnabled="False" ScrollingEnabled="False" ZoomingEnabled="False">
<vc:Chart.AxesX>
<vc:Axis ValueFormatString="{Binding FormatString}" IntervalType="{Binding IntervalType}" Interval="{Binding Interval}" AxisMinimum="{Binding AxisMinValue}" AxisMaximum="{Binding AxisMaxValue}"></vc:Axis>
</vc:Chart.AxesX>
<vc:Chart.AxesY>
<vc:Axis Title="{Binding YAxisTitle}">
</vc:Axis>
</vc:Chart.AxesY>
<vc:Chart.Legends>
<vc:Legend Reversed="True"></vc:Legend>
</vc:Chart.Legends>
<vc:Chart.Series>
<vc:DataSeries RenderAs="Area" XValueType="Date" Color="{DynamicResource AreaChartGradient}" YValueFormatString="#0.00" ToolTipText="#XValue #YValue" LineThickness="1" LegendText="text" SelectionEnabled="True" DataSource="{Binding PCDataPoints}" Bevel="False">
<vc:DataSeries.DataMappings>
<vc:DataMapping MemberName="XValue" Path="Date"></vc:DataMapping>
<vc:DataMapping MemberName="YValue" Path="Value"></vc:DataMapping>
</vc:DataSeries.DataMappings>
</vc:DataSeries>
<vc:DataSeries RenderAs="StepLine" MarkerEnabled="False" XValueType="Date" Color="{DynamicResource LineChartGradient}" YValueFormatString="#0.00" ToolTipText="#XValue #YValue" LegendText="text" LegendMarkerType="Line" LineThickness="2" SelectionEnabled="True" DataSource="{Binding IPDataPoints}">
<vc:DataSeries.DataMappings>
<vc:DataMapping MemberName="XValue" Path="Date"></vc:DataMapping>
<vc:DataMapping MemberName="YValue" Path="Data"></vc:DataMapping>
</vc:DataSeries.DataMappings>
</vc:DataSeries>
</vc:Chart.Series>
</vc:Chart>


I am binding all the values but still getting the exception. I have attached the exception details. Please let me know what might be the cause.

Thanks,

Raams,

Can you please provide the values (Date and Data) you are binding to the series? Also, I would suggest you to try the latest version of Visifire and check.

Hi Vivek,

Thanks for reply.

I pass hundreds of data points (around 300) like below

21-Jun-11 12:00:00 AM - 129.79981
22-Jun-11 12:00:00 AM - 131.5
23-Jun-11 12:00:00 AM - 119.39991
24-Jun-11 12:00:00 AM - 152.39991
......

One more interesting thing is, right now I am getting this exception in only one machine with Windows 7 Home Premium and .net 4.0 installed. In all other machines it works well. I wanted to know why I am getting this exception in that machine only where it works well in all other machines.

Thanks,

I did not find such issue with the above data. Can you please open Region and Language Settings window in that machine and check what DateTime format is set? Also check the same in other machines as well.

Where is the Region and Language settings?

You can search for Regional and Language settings in your start-up programs.

Hi vivek,

I have got same problem again and Visifire throwing exception "String was not recognized as a valid DateTime". When I changed datetime format under "Region and Language settings", it starts working well.

Why visifire does not support all datetime formats? Do we need to take care about all different datetime formats while using visifire? Please let me know as it is crucial for me.

Thanks in Advance.

Thanks,

Rams,

Visifire supports input string only in the en-us format. But chart will be rendered depending upon the current culture.
