  DevExpress CircularGauge To Take Value And PerformanceCounter
  
  Can I show a value a PerformanceCounter in CircularGauge ,
  Code:  
  float val = performanceCounter1.NextValue();
  
         ((DevExpress.XtraGauges.Win.Gauges.Circular.CircularGauge)gaugeControl1.Gauges[0]).Scales[0].Value = val;
  
  A:
  
  In my case for the CircularGauge I had to set both Value and MaxValue together:   
  ((DevExpress.XtraGauges.Win.Gauges.Circular.CircularGauge)gaugeControl1.Gauges[0]).Scales[0].Value = val;
  
  ((DevExpress.XtraGauges.Win.Gauges.Circular.CircularGauge)gaugeControl1.Gauges[0]).Scales[0].MaxValue = GetGaugeMaxValue(val);
  
  ...
  
  // helper function
  private float GetGaugeMaxValue(float val)
          {
              float ret = 100;
  
              if (val < 100)
                  ret = 100;
              else if (val < 1000)
                  ret = 1000;
              else if (val < 10000)
                  ret = 10000;
              else if (val < 100000)
                  ret = 100000;
              else if (val < 1000000)
                  ret = 1000000;
  
              return ret;
          }
  
  see if this helps.
