Create 2-dimensional contour plot from unstructured 3-dimensional data.  Means the points are randomly arranged in the XY plane.

Attached file shows an example of what I would like to achieve.  I think the contour plot Telerik does currently requires a structured grid, i.e. full grid of NxM points.

Please add the Contour series for showing the scatter (X,Y) lines which are connecting the points with the equial Z- coordinate. Currently a scatter 3D surface (X,Y,Z)  can now be shown only as 3D chart.

Often it is necessary to show 3D surface as 2D chart with lines connecting (X,Y) points with "same Z-level" .

The problem arises when we have many graphs on one window and when we scroll to the bottom then to the middle of the window and then resize the width of the window, not all graphics dynamically resize, some harden to the previous size.

I am attaching a project in which you can reproduce the problem.

And I am attaching a video where the problem is clearly demonstrated.

Please solve the problem as soon as possible for our product it is critical!

Release LIB 2022.2.801 (01 August 2022)

LabelRotationAngle applies to labels only in horizontal axis.

It is mainly needed in Vertical axis, when the chart is rotated externally, when placed in rotated panel or control. In this case the vertical axis take the role of a horizontal axis visually and easy way to rotate all labels is needed for readability.

Add mechanism in RadCartesianChart to change the axis origin position. Currently, you can position it only top, left, right or bottom. Add an option to position the axis at an arbitrary position on the opposite axis. For example, to position the horizontal axis in the middle of the vertical axis or at value lets say 3.

I would like to be able to create a histogram where both the x and y axis are linear series and where I can specify the start and end position of each bin (not just one). Previously described workarounds include using StepLineSeries and bar series which cannot have two linear series. I cannot use a scatter plot series as they do not provide the step-wise look of the histogram.  Please add this support!

Currently, the chart provides a selection feature where you can select data points by clicking on their visual elements (ellipses, bars, etc.) or setting the IsSelected property. Add a feature that allows you to select the entire series. This feature is meaningful when using line or area series and you want to highlight (select) the clicked series.

You can easily implement it by subscribing to the MouseLeftButtonDown event of the chart series and change the series' Stroke or Fill property.

When a chart have long labels on the X axis (like date and time) the zoom is not accurate on the horizontal extents with both mouse wheel and drag area.

The reason is probably that the screen coordinates of the selected area are not mapped correctly on the X axis. The mapping works fine for tooltip.

 

You can verify this behavior in the attached Solution. In the images you can see the selected area (01), that the zoomed area is a region with no points (02) and the actual position of the points.

The RadCartesianChart's series allows you to provide a collection of primitive types (like List<int>) to its ItemsSource which will render a proper chart, as shown in the Create Data-Bound Chart article. 

Currently, this is not supported if you use the sampling feature of the chart (ChartDataSource). ChartDataSource can't work with collections with primitive types. Add support for this.

Gaps appear between the bars in the stacks when the series are populated with negative and positive values. Check the attached picture.

If you have a scenario with mixed values (positive and negative) use RangeBarSeries instead of BarSeries.

The chart series allow empty values, which means that if a data point has a null or NaN value there won't be a visual element drawn on the chart. The financial indicator (a type of chart series) support this, but because of their nature, if an ItemsSource is provided, the null values are threaded as zeroes (the number 0) during the automatic generation of data points. This is because, the data point values are calculated based on a function which includes a combination of the previous data item values. 

Add a mechanism like a method override or a property that can alter this behavior. In this case, if the data item of the generated data point contains a null value, the visual element should be dropped (missing) as in the standard chart series.

I would like the possibility to change the color of a line depending on the value.

For example:

I have values between -1 to 10.

If the value is -1 I would like the color (or possible the opacity) to change until it goes back to 0 or above.

Issue1) When no RenderTransformOrigin is set to ScaleAnimation, all slices should be scaled from the pie chart center point. Currently thiss is not true, to better reproduce it , set MaxScale > 1 and notice slices overlap each other at the end of the animation.

Issue2) When RenderTransformOrigin is set to , for example (0, 0), all slices should start animating from topleft corner of the chart. Currently only the first one is animated from top left and all others are animated from pie chart center.
