3D Charts will be a nice addition to the WinForms suite
RadChartView should visualize the pan and zoom state of a view through a scroll bar
When setting the border color of the axis the labels are showing a border with the same color. The color is inherited from the axis element. One should be able to easily disable this, or it should not happen. How to reproduce: public partial class RadForm1 : Telerik.WinControls.UI.RadForm { LineSeries lineSeries; public RadForm1() { InitializeComponent(); this.lineSeries = new LineSeries(); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(25, "Jul")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct")); this.radChartView1.Series.Add(this.lineSeries); this.lineSeries.HorizontalAxis.BorderColor = Color.Green; this.lineSeries.VerticalAxis.BorderColor = Color.Blue; } } Workaround: iterate each of the axis labels and set their border color to Transparent public partial class RadForm1 : Telerik.WinControls.UI.RadForm { LineSeries lineSeries; public RadForm1() { InitializeComponent(); this.lineSeries = new LineSeries(); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(25, "Jul")); this.lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct")); this.radChartView1.Series.Add(this.lineSeries); this.lineSeries.HorizontalAxis.BorderColor = Color.Green; this.lineSeries.VerticalAxis.BorderColor = Color.Blue; } protected override void OnShown(EventArgs e) { base.OnShown(e); foreach (var item in this.lineSeries.VerticalAxis.Children) { AxisLabelElement label = item as AxisLabelElement; if (label != null) { label.BorderColor = Color.Transparent; } } foreach (var item in this.lineSeries.HorizontalAxis.Children) { AxisLabelElement label = item as AxisLabelElement; if (label != null) { label.BorderColor = Color.Transparent; } } } }
The new functionality should allow a display similar to the one in the WPF pie series: http://docs.telerik.com/devtools/wpf/controls/radchartview/features/labels/smart-labels#using-smart-labels-in-radpiechart
When combining scalebreaks and series stacking, the rendered chart does not match the data. See attached solution: The bar of the category "1/2016" has a length of 105 (as indicated by the tooltips) -- but the corresponding axis labeling shows a value of 37. The scalebreak is off too (probably matching the wrong axis).
Note: when you apply a palette the series doesn't have hover and selection indication.
Add Three Line Break Series to RadChartView
The trackball does not work well when charting the dxf cad drawing of a circle or more complex shape would be better for it to have cross hair mode, as single point mode does not work (as it picks up a massive array of x,y points in the tooltip, making it unmanageable) Showtrackball = true SelectionMode = SingleDataPoint
There are three ways in which null values can be handled: 1 . Zero. When this option is used, each null value is replaced with a zero. The data entry is not removed from the data collection. Only its original null/empty value is replaced with zero. 2 . Gap. This option visually removes the regions for each set of empty(null) points. The data entry is not removed from the data collection. Essentially, it connects the points neighboring the null point (or the collection of empty values). 3 . Drop - this option clips, or visually removes each section/segment, corresponding to a set of empty points/values.
It would be great to be able to generate Box Plot graphics, both in the RadCharView control and in the Report.
Good day,
My requierment is to have a RadChartView with a LineSeries and a RangeSeries. I add CategoricalDataPoint objects manually to the LineSeries and I manually add RangeDataPoint objects to the RangeSeries.
When I encounter NULL valued datapoints, for the LineSeries, I do the following. The NULL valued datapoints appear as gaps in the chart as expected.
Dim value As Nullable(Of Double) Dim serControl As LineSeries serControl = New LineSeries() chart.Series.Add(serControl) value = IIf(IsDBNull(dr(data.ControlParameter.ID.ToString())), New Nullable(Of Double), dr(data.ControlParameter.ID.ToString())) serControl.DataPoints.Add(New Telerik.Charting.CategoricalDataPoint(value))
However the RangeSeries do not handle the NULL valued datapoints the same. I get the following error: Nullable object must have a value.
Dim LowerBound, UpperBound As Nullable(Of Double) Dim serRange As RangeSeries serRange = New RangeSeries() chart.Series.Add(serRange) LowerBound = IIf(IsDBNull(dr("Lowerbound"), New Nullable(Of Double), dr("LowerBound")) UpperBound = IIf(IsDBNull(dr("Upperbound"), New Nullable(Of Double), dr("UpperBound")) serRange.DataPoints.Add(New Telerik.Charting.RangeDataPoint(UpperBound, LowerBound))
I need to be able to show gaps, not zero's in a RangeSeries when there are NULL values.
How can I do this?
Improve performance, when calculating the positions of Smart Labels.
Use the following setup:
private void RadForm1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'nwindDataSet.Orders' table. You can move, or remove it, as needed.this.ordersTableAdapter.Fill(this.nwindDataSet.Orders);
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Year, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Quarter, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTim
eGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Month, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.ColumnGroupDescriptions.Add(new PropertyGroupDescription() { PropertyName = "EmployeeID", GroupComparer = new GrandTotalComparer() });
this.radPivotGrid1.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Sum });
this.radPivotGrid1.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Average });
this.radPivotGrid1.FilterDescriptions.Add(new PropertyFilterDescription() { PropertyName = "ShipCountry", CustomName = "Country" });
this.radPivotGrid1.DataSource = this.ordersBindingSource;
this.radPivotGrid1.ChartDataProvider.UpdateCompleted += radPivotGrid1_UpdateCompleted;
this.radChartView1.DataSource = this.radPivotGrid1;
}
private void radPivotGrid1_UpdateCompleted(object sender, EventArgs e)
{
foreach (CartesianSeries series inthis.radChartView1.Series)
{
series.ShowLabels = true;
series.LabelRotationAngle = 90;
}
}
Once you select "% of Grand Total" for one of the aggregates, it would be good the respective chart labels to be formatted in a similar way out of the box:
