How to remove the gap in the chart?

Hello folks,

Recently i got a problem when display the RadChart by using CandleStickSeriesDefinition.

The definition of the series is as follows,

_mainSeriesMapping.SeriesDefinition = new CandleStickSeriesDefinition();
            _mainSeriesMapping.SeriesDefinition.Appearance.StrokeThickness = 1;
            _mainSeriesMapping.SeriesDefinition.Appearance.Stroke = new SolidColorBrush(Colors.Green);
            _mainSeriesMapping.SeriesDefinition.Appearance.Fill = new SolidColorBrush(Colors.Green);

            _mainSeriesMapping.SeriesDefinition.ShowItemToolTips = true;

            var imHigh = new ItemMapping("HighPrice", DataPointMember.High);
            var imLow = new ItemMapping("LowPrice", DataPointMember.Low);
            var imOpen = new ItemMapping("OpenPrice", DataPointMember.Open);
            var imClose = new ItemMapping("ClosePrice", DataPointMember.Close);
            var imXDate = new ItemMapping("ProcessDateTime", DataPointMember.XValue);
            var imYDate = new ItemMapping("ClosePrice", DataPointMember.YValue);


            _mainSeriesMapping.ItemMappings.Add(imHigh);
            _mainSeriesMapping.ItemMappings.Add(imLow);
            _mainSeriesMapping.ItemMappings.Add(imOpen);
            _mainSeriesMapping.ItemMappings.Add(imClose);
            _mainSeriesMapping.ItemMappings.Add(imXDate);
            _mainSeriesMapping.ItemMappings.Add(imYDate);

            rcProduct.SeriesMappings.Add(_mainSeriesMapping);

Then I bind to the my entity and got the picture as the attached file.

In the middle, there is a big gap, this is because in those two days(AxisX) are weekend and has no data. I just want to know how can i remove those weekend days in the chart and got the continuous data.

Thanks very much for your help.

Hello,

Presently, the way to solve this issue would be to remove the entries from the underlying datasource. For example, if the control is bound to a field for its .XCategoty/.XValue. Then, if in out of 100 values, the ones in positions from 20 to 45 have no data, you can simply remove them, and pass a datasource to the chart, which contains no empty points. In this way, the data will be visually continuous.
I hope this gets you started properly.

Best wishes,
