xaxis length

[mrme]

Hi,

I am using Diadem (2012) script to plot some curves.  I want to limit the x and y axis lengths.  I have tried numerous possibilities using variables such as D2AxisYEnd without success.  An extract of where I used "D2AxisXEnd" is shown below.  The script just ignores it and creates a much longer axis(= a default length?).  I am obviously doing something wrong, but I don't know what.  Any help would be gratefully appreciated.

Thanks

Call GraphObjOpen(D2AxisXObj(1))
D2AxisXTxt       ="Speed"
D2AxisXEnd = 500
Call GraphObjClose(D2AxisXObj(1))

To clarify further:- I want to plot just a part of a channel, say the first 200 points using script.  I have tried to do it by limiting the x-axis length using the variable "D2AxisXend".  This will indeed setup the axis with the desired length.  However, when the channel is plotted, all of it is plotted (the full length) and the x-axis is extended to fit the channel length. I could modify the channel length, but I think there must be a better way.  So my question could be:- how to plot just part of a channel without changing its length? 

Thanks to anyone who can help

Hi mrme,

Here's guessing your D2AxisXScaleType property was still set to auto-scale.  Try these 4 variable assignments together:

    D2AxisXScaleType = "begin/end manual"
    D2AxisXBegin     = StartXvalue
    D2AxisXEnd       = StopXvalue
    D2AxisXOrigin    = StartXvalue
