UltimaMeter is an instrumentation analog meter (angular gauge) display ActiveX control specifically designed for data acquisition applications.

• short StartDegree: Start point in degree, which must be smaller than StopDegree (default: 225)

• short StopDegree: Stop point in degree, which must be larger than StartDegree (default: 315)
  

  Example	Settings
  	Start =225 Stop=315
  	Start=270 Stop=360
  	Start=90 Stop=270

  
  

• double MaxValue: The maximum value of the meter

• double MinValue: The minimum value of the meter

• short MainTick: Number of main ticks

• short SubTick: Number of sub ticks between two main ticks

• double Value: Needle position. If any setting is changed, the meter will be redrew first.

• BSTR Unit: Specifies the unit to be displayed

• long Adjustment (short index): Adjustment
  

  Index
  0	Horizontal offset for the meter center
  1	Vertical offset for the meter center
  2	Number of digits after decimal point to be displayed for Value
  3	Number of digits after decimal point to be displayed for the tick annotations
  6	Numerator of the meter ratio
  7	Denominator of the meter ration
  8	Reset min/max retainers
  9	Enable (1) or disable (0) min/max retainers, see below
  10	Length of the retainer needles in percentage of the gauge diameter
  Others	Reserved

   

• BSTR Key: 

  1. Enter command Keys

     • Control the font size for the numbers

       • Command key format is "@, <size-divisor>"

       • The default divisor is 6, a positive number should be used here

       • Example:
         
         UltimaMeter.Key ="@,10" --- make the font smaller
         

  2. Enter the registration key. 

  Until UltimaMeter is paid-registered, it will display the watermark of "www.ultimaserial.com" in the upper left corner (see below)

  

• Boolean ShowColorBand: Enable or disable the color limit band

• OLE_COLOR Palette (short index): 

  Index
  0..3599	Specifying the color for each matching limit.  ymax = 360 ylo = 100 yhi = 300 For i = 0 To ymax       If i < ylo Then          BLUE = C255 - Int((c256 * i) /  ylo)          GREEN = Int((c256 * i) /  ylo)          RED = 0     Else         If (i >= yhi) Then             BLUE = 0             GREEN = C255 - Int(((i - yhi) * C255) / ((ymax - yhi)))             RED = Int(((i - yhi) * C255) / ((ymax - yhi)))         End If     End If     UltimaMeter1.Palette(i) = BLUE * C65536 + GREEN * c256 + RED  Next
  10000	Color for the gauge needle
  10001	Color for the meter ring edge
  10002	Color for the meter ring center
  10003	Color for the number and text
  10004	Color for the meter face
  10008	Color for the min retainer
  10009	Color for the max retainer
  Others	Reserved

   

• double LimitBand  (short index): Specifying the limit for each matching color band. Up to 3600 limits can be specified.
  
  ymax=360
  For i = 0 To ymax - 1
       UltimaMeter1.LimitBand(i) = ((UltimaMeter1.MaxValue - UltimaMeter1.MinValue) / ymax) * i + UltimaMeter1.MinValue
  Next
  
  UltimaMeter1.LimitBand(ymax) = UltimaMeter1.MaxValue 'This is a must to indicate the end of limit bands!
