    I have a RadHtmlChart on my page using the Bootstrap theme, as shown in the attached screenshot. I currently have the figures for the columns displaying, i.e. 1 and 2 in the columns Jan and Feb. Is it possible to high the figures when a 0 is returned, rather than displaying them on the x axis. But obviously keeping the values if they are greater than 0.

    Also you will notice in the screenshot that when I hover over a bar, there is a tooltip displaying the data value. Is it also possible to disable these tooltips?

    Hello David,

    Straight to your questions:
    1. Hiding a series item when its value is equal to zero is not a built-in functionality - after all, there are situations when you actually want to display the item. What I can suggest here is to iterate through your data source and check if a specific value is equal to zero and if so - simply do not create a series item.

      If you are binding the chart (and not adding its items programmatically), you will need to manually filter the data source beforehand and bind the chart to the new one.
    2. You can hide the tooltips using the Visible property:
      <telerik:RadHtmlChart runat="server" ID="Chart">
                      <TooltipsAppearance Visible="false"></TooltipsAppearance>
