Graphing Multiple 3D Graph Types with Spherical Data Points

Question

I have data points that are in theta, phi and r (magnatude) that I would like to be able to 3D plot and change the text/contour to either wireframe or contoured or points on the fly.  I believe this is possible however, after looking at the NI examples, they are all done with xyz coordinates and have yet to see a 3D graph with spherical (NI, take this as a suggestion ).
Over a year ago, I was able to create data in spherical by giving it 3 1D arrays, but it only plotted it in the form of point or line.  The examples that have a torus use parametric plots?! although I am not entirely sure I understand how it works nor how to convert to it from spherical.
Attached is a sample input file/array.  Wanted to see if anyone had experience using the built in 3D libraries (CW 3D Graph
8.0) to achieve something similar.
Note: the Amplitude column is absolute and could be made positive for ease of use as well.
Thanks

I'm just trying the following in the main loop to get something to graph, and nothing is showing up but this error - 80020009
static int panelHandle;
static CAObjHandle gGraph;
//==============================================================================
// Static functions
//==============================================================================
// Global variables
//==============================================================================
// Global functions
/// HIFN The main entry-point function.
int main (int argc, char *argv[])
int error = 0;
VARIANT xVt, yVt, zVt;
HRESULT hr;
int i,j;
char errCode[100];
double xData[50], yData[50], zData[50][50];
/* initialize and load resources */
nullChk (InitCVIRTE (0, argv, 0));
errChk (panelHandle = LoadPanel (0, "3D Analysis.uir", PANEL));
/* display the panel and run the user interface */
errChk (DisplayPanel (panelHandle));
CA_VariantSetEmpty(&xVt);
CA_VariantSetEmpty(&yVt);
CA_VariantSetEmpty(&zVt);
for (i = 0; i < 50; i++) {
xData[i] = yData[i] = i;
for (j = 0; j < 50; j++) {
zData[i][j] = i*j;
GetObjHandleFromActiveXCtrl(panelHandle, PANEL_CWGRAPH3D, &gGraph);
errChk (CA_VariantSet1DArray(&xVt,CAVT_DOUBLE, 50, xData));
errChk (CA_VariantSet1DArray(&yVt,CAVT_DOUBLE, 50, yData));
errChk (CA_VariantSet2DArray(&xVt,CAVT_DOUBLE, 50,50,zData));
errChk (CW3DGraphLib__DCWGraph3DPlot3DSurface(gGraph, NULL,xVt,yVt,zVt, CA_DEFAULT_VAL));
//errChk (CW3DGraphLib_CWPlot3DPlot3DSurface (gGraph, NULL, xVt, yVt, zVt, CA_DEFAULT_VAL));
errChk (RunUserInterface ());
Error:
/* clean up */
sprintf(errCode,"%X",error);
MessagePopup("",errCode);
CA_VariantSetEmpty(&xVt);
CA_VariantSetEmpty(&yVt);
CA_VariantSetEmpty(&zVt);
CA_DiscardObjHandle(gGraph);
DiscardPanel (panelHandle);
return 0;
At this point, I am just trying to figure out which function to call and what to set the input Variants.  Seems somethings they are 1D and sometimes they are 2D.  Unfortunately the documentation is very slim and doesn't explain what the actual functions or variants represent.
