Classic Dashboard Single Value visual change background color to transparent

[MrJohn230]

Hello, can someone provide feedback on how I can change the color of my panel to transparent? Below is my code snippet. I'm not great with CSS or XML. I was using dashboard studio which was straight forward on how to change but I'm back with classic for now. 

    <panel>
      <single>
        <title>Total First Time</title>
        <search base="base_search">
          <query>|search Cur= $t_cur$ | bin _time span=$t_bin$ | stats sum(FirstTime) as sumFirstTime by Category</query>
        </search>
        <option name="drilldown">none</option>
        <option name="rangeColors">["0x53a051","0x0877a6","0xf8be34","0xf1813f","0xdc4e41"]</option>
        <option name="refresh.display">progressbar</option>
      </single>
    </panel>

Hey @MrJohn230,

In the classic dashboard framework, changing the background color of the chart is something that is not possible.  In the dashboard studio, you can update the options parameter to change the background color.

Reference for Dashboard studio - single value visualization - https://docs.splunk.com/Documentation/Splunk/9.1.2/DashStudio/chartsSV#Single_value_2

For having a background color in classic dashboard, you would need to use charts and not the single value visualization - https://docs.splunk.com/Documentation/SplunkCloud/9.1.2308/Viz/ChartConfigurationReference
