I have RadChart that populated with real time data.

private Random random;

private DataSeries series;

This is my RadChart configuration:

rcStatistics.Background = Brushes.Transparent;

rcStatistics.BorderBrush = Brushes.Transparent;

rcStatistics.DefaultView.ChartLegend.Visibility = System.Windows.Visibility.Collapsed;

rcStatistics.DefaultView.ChartArea.AxisX.Visibility = System.Windows.Visibility.Hidden;

rcStatistics.DefaultView.ChartArea.AxisY.Visibility = System.Windows.Visibility.Hidden;

My chart is populated with real time data via timer, this is my timer tick event:

int val = random.Next(0, 100);

series.Add(new DataPoint(val));

rcStatistics.DefaultView.ChartArea.DataSeries.Add(series);

Please see my attach screenshot:

1. How can i remove value label ?

2. How can i remove the upper and the lower 2 stripes that i have on my chart ?

3. As you can see my chart series line is fill only half of my chart and this is how it is all the time and in additional after adding few points into my chart my application is stuck and become more slow, why this is happening and how can i fix it ?

Hi,

We have two charting solutions at this time - the old RadChart and the new RadChartView. The old RadChart does not have a very good performance and has many limitations and this is why we suggest you do not use it at all for new development. I suggest you completely remove the Charting.dll reference. We suggest you use the new RadChartView, which is a set of controls - RadCartesianChart, RadPieChart, RadPolarChart, ChartDataSource. It is much faster, very flexible and easy to set up. References below:
