Hello Mutlag,

I'm afraid that currently the RadPolarChart doesn't support zooming. However, could you provide us more information about your scenario and the behavior you expected (e.g. to decrease axis maximum by mouse wheel or something else). 

Thank you in advance for your cooperation.

Hello,

I have the same problem here. I want to add a zooming behaviour to my RadPolarChart, just like the ChartPanAndZoomBehaviour for a RadCartesianChart.

So unfortunately it is not enaugh to descrease the axis maximum by mouse wheel. For example I want to zoom in the right corner of my polar chart.

Is there something released now or can you give me an advice to build this?

Thank you and best regards,

Sandra

Hello Sandra,

As my colleague Milena explained we don't support zooming for RadPolarChart and I'm afraid currently we don't have plans to provide such functionality. Luckily you can achieve the desired zooming on mousewheel very easy -- by tweaking the Maximum value of the PolarAxis. I attached a small sample demonstrating that. Feel free to modify it as you wish. Can you clarify whether it meets your requirement?

Hello Evgenia,

Unfortunately this doesn't cover my requirements... 

What I actually need is to zoom into any section of the PolarChart. If you have any ideas, these will be happily welcomed.

Thank you and best regards

Hi Sandra,

I'm sorry to hear that the provided project doesn't meet your requirements.
I'll dissapoint you but we haven't heard of zooming only in the right corner of the Polar chart. You can still try and workaround this by extending the Size of the Chart on mouse wheel (this will imitate zooming in) and then implement your own Pan behaviour if you want. 
Please mind that this is out of our support scope and is something that you should do on your own.
