How to show a chart (line series) starting from zero?

I'm using DataVisualization from WPF Toolkit.

I'm using LineSeries to show the data in the graph. But there's an inconvenience.

Is possible that the line start in zero? I have drawed a red line, I'd like to show it.

This is the code what I'm using:

            <ChartTools:Chart x:Name="SubobjectivesChart" Background="LightSteelBlue">
                <ChartTools:Chart.Axes>
                    <ChartTools:LinearAxis Orientation="Y" ShowGridLines="True"  Minimum="0" Maximum="1" />
                </ChartTools:Chart.Axes>

                <ChartTools:Chart.Series>
                    <ChartTools:ColumnSeries Title="Exam" ItemsSource="{Binding Subobjectives}" Background="Black" IndependentValueBinding="{Binding Exercise}" DependentValueBinding="{Binding Average}" >
                    </ChartTools:ColumnSeries>
                </ChartTools:Chart.Series>
            </ChartTools:Chart>

This may not be true for WPF, but using the Forms designer I found an IsMarginVisible property for my project. It's under ChartArea > Axis > Scale.

Although, I may not be fully understanding the question. If you really want it to go to zero, there is an "EmptyPointValue" option under Series > Misc > CustomPropertes. Could set that to "Zero".

No it's not and it shouldn't be possible. Chart is just a visual representation provider for your data. Just change your data accoridngly by rounding it down.
