Part 8 Apply customization options with dashboard default settings

By adjusting the dashboard default settings, you can avoid repetition while applying the same customization options to multiple visualizations or data sources. For example, you can apply a default setting to just one type of visualization, such as an area chart. Or, you can apply a default setting to all visualizations, but exclude one type.

More local, or specific, default settings override more global, or generic, default settings. Adjusting the settings of one particular area chart, for example, overrides any default settings set for all area charts.

1. Open the source code editor ().
2. In the defaults stanza, add the following source code after the dataSources section:

   "visualizations": {
              "splunk.area": {
                  "options": {
                      "xAxisTitleVisibility": "hide"
                  }
              }
          }
   

   1. For Dashboard Studio in Splunk Enterprise, in the defaults stanza, add the following source code after the dataSources section:

   "visualizations": {
              "viz.area": {
                  "options": {
                      "axisTitleX.visibility": "collapsed"
                  }
              }
          }
   

   Now, the defaults stanza in the source code looks like this:

   "defaults": {
          "dataSources": {
              "ds.search": {
                  "options": {
                      "queryParameters": {
                          "latest": "$global_time.latest$",
                          "earliest": "$global_time.earliest$"
                      }
                  }
              }
          },
          "visualizations": {
              "splunk.area": {
                  "options": {
                      "xAxisTitleVisibility": "hide"
                  }
              }
          }
      },
   

3. Return to the visual editor by selecting Back. Notice that there is no x-axis label in either area chart.
