    Hello, I am currently working on building a four-quadrant point chart and have a few questions and one issue.

    Questions:

    1. How do I remove the X and Y axis lines that show where 0 is on the chart?
    2. Is there a way to set how far in you zoom when you click on the chart?
    3. How do I set custom strip lines at a specified point for both X and Y?

    Issue:

    1. Tooltips are not working when Zoom is enabled, when I disable Zoom the tooltips display again.

    Hello Anna,

    Onto your questions:
    • You can make the X and Y axis lines transparent like this:
    <telerik:RadChart ID="RadChart1" runat="server">
        <PlotArea>
            <XAxis Appearance-Color="Transparent" />
            <YAxis Appearance-Color="Transparent" />
        </PlotArea>
    </telerik:RadChart>
    • Zooming in RadChart works on drag-to-zoom principle (and not click-to-zoom) so we are a bit unsure what kind of functionality are you looking for on this one.
    • RadChart does not provide built-in support for custom striplines so indeed using marked zones is the easiest way to achieve the desired effect.

    As for tooltips and zooming and scrolling -- this is a known limitation of the control and unfortunately it cannot be worked around (when zooming and scrolling is enabled, all interactivity features like click events, tooltips, etc. are disabled).
