Binding data to UltimateXF chart from view model

I am using https://nuget.org/packages/UltimateXF/ charts in my app and I know how to set data from code behind. My problem is I want to know how to bind data from view model.

     <StackLayout Orientation="Vertical" Padding="2" VerticalOptions="FillAndExpand" Grid.Row="1">
              <Label Text="Target/achievement" FontSize="Default" TextColor="DarkSlateGray"/>
              <Label Margin="10,-5,0,0" HorizontalOptions="StartAndExpand" Text="4000/5000" FontSize="18" TextColor="Black"/>
              <ultimateChart:SupportHorizontalBarChartExtended HeightRequest="60" x:Name="lineChart" Margin="0,0,0,0" HorizontalOptions="FillAndExpand"/>
</StackLayout>

This is how I bind data from code behind....

            var labels = new List<string>();
            var lineEntries = new List<EntryChart>();

            lineEntries.Add(new EntryChart(0, 500));
            lineEntries.Add(new EntryChart(1, 200));

            labels.Add("Gene");
            labels.Add("Life");

            var lineDataSet4 = new BarDataSet(lineEntries, "")
            {
                Colors = new List<Color>{
                    Color.LightSalmon
                }
            };

            var lineData4 = new BarChartData(new List<IBarDataSet>() { lineDataSet4 });

            lineChart.ChartData = lineData4;
            lineChart.DescriptionChart.Text = "";
            lineChart.AxisLeft.DrawGridLines = false;
            lineChart.AxisLeft.DrawAxisLine = true;
            lineChart.AxisLeft.Enabled = true;

            lineChart.AxisRight.DrawAxisLine = false;
            lineChart.AxisRight.DrawGridLines = false;
            lineChart.XAxis.Granularity = 1f;
            lineChart.HeightRequest = 10;
            lineChart.AxisRight.Enabled = false;

            lineChart.XAxis.XAXISPosition = XAXISPosition.BOTTOM;
            lineChart.XAxis.DrawGridLines = false;
            lineChart.XAxis.AxisValueFormatter = new TextByIndexXAxisFormatter(labels);
