Evenly-Spaced Waterfall Plot Example

In this example we create a waterfall plot with evenly-spaced X and Y values that come from the X and Y

scaling of the matrix being plotted.

Function EvenlySpacedWaterfallPlot()

// Create matrix for waterfall plot

Make/O/N=(200,30) mat1

SetScale x,-3,4,mat1

SetScale y,-2,3,mat1

mat1=exp(-((x-y)^2+(x+3+y)^2))

mat1=exp(-60*(x-1*y)^2)+exp(-60*(x-0.5*y)^2)+exp(-60*(x-2*y)^2)

mat1+=exp(-60*(x+1*y)^2)+exp(-60*(x+2*y)^2)

// Create waterfall plot

NewWaterfall /W=(21,118,434,510) mat1

ModifyWaterfall angle=70, axlen= 0.6, hidden= 3

// Apply color as a function of Z

Duplicate mat1,mat1ColorIndex

mat1ColorIndex=y

ModifyGraph zColor(mat1)={mat1ColorIndex,*,*,Rainbow}

End

Unevenly-Spaced Waterfall Plot Example

In this example we create a waterfall plot with unevenly-spaced X and Y values that come from separate

1D waves.

Function UnvenlySpacedWaterfallPlot()

// Create matrix for waterfall plot

Make/O/N=(200,30) mat2

SetScale x,-3,4,mat2 // Scaling is needed only to generate

SetScale y,-2,3,mat2 // the fake data

mat2=exp(-((x-y)^2+(x+3+y)^2))

mat2=exp(-60*(x-1*y)^2)+exp(-60*(x-0.5*y)^2)+exp(-60*(x-2*y)^2)

mat2+=exp(-60*(x+1*y)^2)+exp(-60*(x+2*y)^2)

SetScale x,0,0,mat2 // Scaling no longer needed because we will

SetScale y,0,0,mat2 // use X and Y waves in waterfall plot

// Make X and W waves

Make/O/N=200 xWave = 10^(p/200)

Make/O/N=30 yWave = 10^(p/30)

// Create waterfall plot

NewWaterfall /W=(21,118,434,510) mat2 vs {xWave,yWave}

ModifyWaterfall angle=70, axlen= 0.6, hidden= 3
