    Is it possible to scale a chart series by setting a max and min value? I have a RadCartesianChart with X = weight and Y = date values. The weight goes from 0 to 140 but most of my values are all within 120 - 140 range. If I could set the max and min weight values to plus 10% and minus 10% the chart would have more detail. Here is my code
                      <telerikChart:LinearAxis LineStroke="{StaticResource PhoneDisabledBrush}" LineThickness="2"/>
                      <telerikChart:DateTimeCategoricalAxis LabelFitMode="Rotate" DateTimeComponent="Date" LabelFormat="M-yy" ></telerikChart:DateTimeCategoricalAxis>
                  <telerikChart:LineSeries x:Name="lines" Stroke="{StaticResource PhoneAccentBrush}" CategoryBinding="WeighDate" ValueBinding="WeighAmount">

    See attached example to see how the chart has little detail because of the scaling.

    I attempted to set the min and max values from my data but the code failed, object null:

    double myMin = myWs.Min(minW => minW.WeighAmount);
                double myMax = myWs.Max(maxW => maxW.WeighAmount);
                xCartesionChart.Series[0].ItemsSource = myWsSorted;
                lines.MaxHeight = myMax;
               lines.MinHeight = myMin;

    Hi Robery,

    Yes of course. You just need to set the Minimum and Maximum properties of your LinearAxis. It should look like this for example:

    <telerikChart:LinearAxis LineStroke="{StaticResource PhoneDisabledBrush}" LineThickness="2"
    The MinHeight and MaxHeight are different, you almost never need to set those manually.
