DIADEM Y AXIS AUTOSCALE METHOD?

[Jim West]

I have a requirement of having 10 ticks for the Xand Y axes. The X is easy but I need to trigger an autoscale for the Y axis. I have been using the Picupdate command to do this. The problem is that the Picupdate takes a ”long" time to complete since I have complex plots. Is there another way to trigger an autoscale for just a specific axis?

Jim

here is current code

IF AUTO = 1 THEN

Call GRAPHObjOpen(AxisID)           ' Open the Axis object
  Call GRAPHObjOpen(D2AxisYObj(axis))
     D2AxisyScaleType  = "complete automatic"
  Call GRAPHObjClose(D2AxisYObj(axis))
Call GRAPHObjClose(AxisID)

call picupdate ' to set the scales
  END IF
Call GRAPHObjOpen(AxisID)           ' Open the Axis object
  Call GRAPHObjOpen(D2AxisYObj(axis))

    IF AUTO = 1 THEN

        min = D2AXISYBEGIN 'get autoscale values
        max = D2AXISYend
    ELSE
        min     = Y_MIN
        max     = Y_MAX
    END IF
   
        D2AxisyScaleType  = "manual"
        D2AXISyBEGIN     = MIN
        D2AXISyEND       = MAX
        D2AxisyDivMode    = "linear"
        D2AxisyOrigin     = MIN
        IF ((MAX - MIN) <> 0) THEN
          D2AxisyTick       = Abs(MAX - MIN) / 10
        END IF
        D2AxisytickBegin  = MIN
  Call GRAPHObjClose(D2AxisYObj(axis))
Call GRAPHObjClose(AxisID)

Hi Jim,

yes there is a better solution. You can use the command

Call GraphObjScalingUpdate(AxisID) 'Update scaling of selected object

instead of "picupdate".

This command updates the axis system without drawing it. There is no command to update only the Y axis but if the X axis is already manual scaled it will not be touched.

Thank you for the tip-Why can't I ever find these things? Jim
