For scientific purpose, I have this kind of polar chart
I would like to implement a radius zoom on this plot. The HorizontalZoomable/VerticalZoomable is not suitable, I need the the pattern to be centered.
I have disabled the HorizontalZoomable/VerticalZoomable and overriden the mouse wheel event to change the MaximumValue of the NumericRadiusAxis.
It works pretty well except that the out of range values are ignored, the user will think there is no value (see result below)
The documentation states:
By default, data charts use auto range, which means that the MinimumValue property will be set to the data point with the smallest radius data column and the MaximumValue property will be set to the data points with the largest radius data column. However, manually setting a value range on NumericRadiusAxis will hide all data points with radius data column outside this range.
Is there a way to crop the curve in that case (to keep the zoom behavior) ?
Hello Alexandre,
Thank you for your post. I have been looking into it and I am wondering if you can send us an isolated sample project with your implementation, so we could be able to investigate this further for you.
Looking forward for your reply.
Hello Stefan,
you will find attached a sample demo. The mouse scroll wheel will change the max magnitude (shift + scroll combination will change the minimum)
Our problem with Infragistics polar plot is that the zoom is not "valid" for scientific purpose.
With a zoom, the user wants to see it's plot within a specific range. On a cartesian plot, the rectangular selection is perfect. But on a polar plot, the rectangular selection is not relevant.
Thanks in advance

Hello Alexandre
After working on this and doing some research, our developers said that due to technical expense the design of the polar series is to filter out values that are outside the explicit range of the radius axis. You can suggest supporting a polar series to have a broken shape due to lines crossing the maximum of the radius axis as new product idea You can suggest new product ideas for future versions (or vote for existing ones) at http://ideas.infragistics.com.
There are many benefits to submitting an product idea:
- Direct communication with our product management team regarding your product idea.
- Notifications whenever new information regarding your idea becomes available.
- Ability to vote on your favorite product ideas to let us know which ones are the most important to you. You will have ten votes for this and can change which ideas you are voting for at any time.
- Allow you to shape the future of our products by requesting new controls and products altogether.
- You and other developers can discuss existing product ideas with members of our Product Management team.
Steps to create your idea:
1. Log into the Infragistics Product Idea site at http://ideas.infragistics.com (creating a new login if needed).
2. Navigate to the product / platform channel of your choice (e.g. WPF, Windows Forms, ASP.NET, HTML5 / Ignite UI, iOS / NucliOS, etc.)
3. Add your product idea and be sure to be specific and provide as much detail as possible. Explain the context in which a feature would be used, why it is needed, why it can’t be accomplished today, and who would benefit from it. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. Be convincing!
4. “Include a link to this thread” in your idea so product management will be able to look back at this case.
The Product Idea site puts you in the driver’s seat and allows you to track the progress of your ideas at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.
