the method CW3DGraphLib__DCWGraph3DPlot3DCurve does not work

[Honzik]

Hello

I have problem with 3D graph, I want draw only simple curve, here is my code

 data1[0]=1;

data1[1]=8;

data1[2]=9;

data1[3]=6;

data2[0]=9;

data2[1]=2;

data2[2]=4;

data2[3]=5;

data3[0]=6;

data3[1]=2;

data3[2]=9;

data3[3]=8;

    VARIANT xArray,yArray,zArray;

GetObjHandleFromActiveXCtrl (panelHandle,PANEL_CWGRAPH3D , &graphHandle); CW3DGraphLib__DCWGraph3DGetPlots (graphHandle, NULL, &plotsHandle); CW3DGraphLib_CWPlots3DItem (plotsHandle, NULL, CA_VariantInt(1),&plotHandle);

CA_VariantSet1DArray (&xArray, CAVT_DOUBLE, 4, &data1);

CA_VariantSet1DArray (&yArray, CAVT_DOUBLE, 4, &data2);  

CA_VariantSet1DArray (&zArray, CAVT_DOUBLE, 4, &data3);  

CW3DGraphLib__DCWGraph3DPlot3DCurve (plotHandle, NULL, xArray, yArray, zArray, CA_DEFAULT_VAL);

Thank you for help

Dear Honzik,

in order to do what you want to do, you need to replace:

CW3DGraphLib_CWPlots3DItem

with a function

CW3DGraphLib_CWPlots3DAdd

I can visualize it in LabVIEW:

Hope this helps.

If you have more problems, you can have a look at the following forum threads:

Thank you for your answer

but if I replace it, it doesn't draw anything. I have simply task, draw some points into defined positions x,y,z. Plot surface works but there is some 2D array and I need 3D.

Dear Jan,

it should work in this configuration. Could you post your project files here?

As I wrote before, I used the same ActiveX functions in LabVIEW and it worked.

here is my project, it is very simple only for testing 3D graph

thank you

Dear Jan,

please try:

                GetObjHandleFromActiveXCtrl (panelHandle,PANEL_CWGRAPH3D , &graphHandle);
                CW3DGraphLib__DCWGraph3DGetPlots (graphHandle, NULL, &plotsHandle);        
                CW3DGraphLib_CWPlots3DAdd (plotsHandle, NULL,&plotHandle);    
            
                double data1[4];
                double data2[4]; 
                double data3[4]; 
    
                data1[0]=1;
                data1[1]=8;
                data1[2]=9;
                data1[3]=6;
                
                data2[0]=9;
                data2[1]=2;
                data2[2]=4;
                data2[3]=5;
                
                data3[0]=6;
                data3[1]=2;
                data3[2]=9;
                data3[3]=8;
    
                ERRORINFO i;  
                VARIANT xArray,yArray,zArray;
     
                CA_VariantSet1DArray (&xArray, CAVT_DOUBLE, 4, &data1);
                CA_VariantSet1DArray (&yArray, CAVT_DOUBLE, 4, &data2);  
                CA_VariantSet1DArray (&zArray, CAVT_DOUBLE, 4, &data3); 
            
                CW3DGraphLib_CWPlot3D_CIPlot3DCurve (plotHandle, NULL, xArray, yArray, zArray, CA_DEFAULT_VAL); 
                 
                CA_VariantClear (&xArray);
                CA_VariantClear (&yArray); 
                CA_VariantClear (&zArray);

Thank you, it works.
