Hi Yanko,

Thanks!    The xamZoomBar can draw left side and right side, can the top side and bottom side also support drawing?

Hello Charlie,

Thank you for your post. I have been looking into your question and you could move the thumb of the XamZoombar up and down by setting the ‘Orientation’ property of the XamZoombar to “Vertical”.

Let me know, if you need any further assistance on this matter.

Hi Yanko,

Thanks for your quick response, maybe I didn't make myself clear, I want both vertical and horizon side can move.  

Hello Charlie,

I am just checking if you require any further assistance on the matter.

Hi Charlie,

Thank you for your reply. Regarding your first post you are explaining that you would like to use the XamZoombar only for the plot area of the XamDataChart(without covering the labels area). This is why I suggested you insert the XamZoombar using code-behind in order to remove the canvas that holds the plot area, add the XamZoombar and after that add the canvas again. This functionality cannot be achieved using XAML only.

If you would like the XamZoombar to cover the entire XamDataChart, you need to remove the ‘Loaded’ event handler of the XamDataChart.

Let me know, if you need any further assistance on this matter.

Hi Yanko,

I'm not very clear about the question "xamzoombar cover the chart" in the solution you provided . 

In your solution, you created the xamzoombar in the code-behind, but in my project, the xamzoombar is defined in the xaml page. So I try to modify the solution you provdeded to meet my requirement, but it didn't work, the dataChart is missing, only a zoomBar.  

I have attached the modified solution. Please help.
