Using strings as axisname while using AppendToGraph

Share icon

Hello All,
When working with small number of waves, the AppendToGraph command with literal axis name works fine, or we can just use the GUI.

For example, AppendToGraph /B=B1 wave0

However, I am trying to achieve this in a procedure where I can plot multiple waves automatically.

I generate the 'axisname' which is stored in a string, and I want to pass this to AppendToGraph; something like

AppendToGraph /B=(stringVariable) wave0

I get error "ill formed name".
Alternatively, I tried storing the axisnames in text wave and then pass the axisname in a loop to iteratively append to the graph. This also did not work.
Any suggestions. (Following is a procedure which explains what I am trying.)

// Function to plot multiple waves on different axes and modify them on the fly.

function autoPlot_test()

// This is for testing hence waves are generated herein!

// Generate 4 waves here
make /o/d /n=200 f1=sin(p/0.01)
make /o/d /n=200 f2=sin(p/0.05)
make /o/d /n=200 f3=cos(p/0.01)
make /o/d /n=200 f4=cos(p/0.05)

wave f1=f1

variable i
variable x1=4
string wname
string axis

// display the first plot
display f1      // axisname becomes 'left / bottom'

// make text wave for axis names
make /o /T /n=(x1) axisLabel

// make wave for axis intervals
make /o /n=(x1) intMin, intMax

wave /T axisLabel = axisLabel
wave intMin = intMin
wave intMax = intMax

// Axis label
axisLabel[0] = "bottom" // first value

// Axis intervals, 4 intervals for 4 waves
intMin[0]=0 ; intMax[0]=0.22
intMin[1]=0.25 ; intMax[1]=0.47
intMin[2]=0.5 ; intMax[2]=0.77
intMin[3]=.79 ; intMax[3]=1.0


// Loop for appending to plot
for (i=1 ; i<x1 ; i=i+1)
   
    sprintf wname, "f%g", i
    sprintf axis , "a%g",i
   
    wave w0=$wname
   
    axisLabel[i] = axis

    print nameofwave(w0), axis, intMin(i), intMax(i)
   
    // Want to split into three sections horizontally with three waves -----
   
    AppendToGraph /B=(axis)  w0     // remove the paranthesis around (axis) to compile
   
    // AppendToGraph /B=[(axisLabel[i])]  w0
   
    ModifyGraph axisEnab(axis) = { intMin(i), intMax(i) }
   
    // ModifyGraph freePos(axis)=0
    // --------------------------------------------------------------------------
endfor

end

I think the issue is that the axis name is a literal and not a string.
This means, that you would have to deref the string: $s_string.

So this ought to work:
make/o/n=10 w_wave = enoise(10)
string s_axis = "bottom"

appendtograph /b=$s_axis w_wave


best,
