title: How to set font attributes for all text in a chart?
body: <p>I have a ZingChart (through cfchart) that has an external JSON styling file. How can I set font attributes, such as font-family, font-weight, font-size for all text in the chart, without setting it individually?</p>
  
  <p>My JSON file so far:</p>
  
  <pre><code>{
  "graphset":[
      {       
          "background-color":"white",
          "font-family":"Courier New",
          "scale-x":{
              "label":{
                  "text":"Date"
              }
          },
          "scale-y":{
              "label":{
                  "text":"Score"
              },
              "markers":[
                  {
                      "type":"line",
                      "range":[75,76],
                      "line-color":"red"
                  },
                  {
                      "type":"line",
                      "range":[50,51],
                      "line-color":"yellow"
                  }
              ]
          },
          "tooltip" : {
              "text" : "Score of %v on %k",
              "background-color" : "#ff9900"
          },
          "plot":{
              "marker":{
                  "type":"square"
              }
          }
      }
    ]
  }
  </code></pre>
  
  <p>I know that I can add it individually for, say, all scale-x "item"s":</p>
  
  <pre><code>"scale-x":{
              "label":{
                  "text":"Date"
              },
               "item":{ 
                  "font-angle":320,
                  "font-family":"Arial",
                  "font-weight":"bold",
                  "font-size":13
              }
          }
  </code></pre>
  
  <p>But I want to add it for all text in the chart.</p>
