Set color of LineSeries depends on data

[William]

I want the color of lineseries depends on the data value, if current value >0, the color should be green, if the current value <0, the color should be red.

How to implement?

Hi William,

Thanks for contacting Syncfusion support.

We have achieved your requirement by using the custom palette feature. We have prepared the sample based on your requirement.

Hi Santhiya

Thanks for support, I found such code in your sample:

            for (int i = 0; i < viewModel.DataPoint.Count; i++)
            {
                if (viewModel.DataPoint[i].YData > 0)
                    chart.Series[0].ColorModel.CustomBrushes.Add(new SolidColorBrush(Colors.Green));
                else
                    chart.Series[0].ColorModel.CustomBrushes.Add(new SolidColorBrush(Colors.Red));
            }

Is that the only way to set color dynamically? Is there any easier way? like use Data binding the SolidColorBrush in XAML?

Hi William,

We had achieved your requirement by using data binding in the ChartSeries ColorModel property. We have modified the sample based on your requirement.

Please find the sample from the below link.
