Hi folks
I use version 7.5. I want to create a wafermap out of (random)XYZ data. To create a matrix and just delete the edges of the square does'nt look good enough in a contour plot. I'm looking for a circle like border for the contour plot.
Can sombody help? |

This is a C code which will do the work:
#include <origin.h>
void mkcircle(double dOutsideVal = -999)
{
MatrixLayer ml = Project.ActiveLayer();
Matrix mm(ml);
int nRows = mm.GetNumRows();
int nCols = mm.GetNumCols();
int nrc = nRows/2.0; // nearest int = 0.5 + nRows/2.0;
int ncc = nCols/2.0;
double rr = min(nrc, ncc);
for(int nr = 0; nr < nRows; nr++)
{
for(int nc = 0; nc < mm.GetNumCols(); nc++)
{
double xsqr = (nr - nrc)^2;
double ysqr = (nc - ncc)^2;
if(sqrt(xsqr + ysqr) > rr)
{
mm[nr][nc] = dOutsideVal;
}
}
}
}

This script from a sample project in our KBase does what you want:
//BEGIN SCRIPT
r=abs(layer.y.to-layer.y.from)/2;
c=abs(layer.x.to-layer.x.from)/2+layer.x.from;
h=abs(layer.y.to-layer.y.from)/2+layer.y.from;
create Circle -wd 200 A B TempA TempB;
circle_A=data(layer.x.to,layer.x.from,(layer.x.from-layer.x.to)/99);
circle_b=h+sqrt(r^2-(circle_A-c)^2);
circle_TempA=data(layer.x.from,layer.x.to,(layer.x.to-layer.x.from)/99);
circle_Tempb=h-sqrt(r^2-(circle_A-c)^2);
copy -b 1 circle_TempA Circle_A -b 101 -e 200;
copy -b 1 circle_TempB Circle_B -b 101 -e 200;
delete circle_TempA;
delete circle_TempB;
layer -i circle_B;
set circle_b -pf 1; // enable fill area
set circle_b -pfv 3; // set fill "exclusive,..."
set circle_b -pfb 18; // set fill color to white
// END SCRIPT
Have your contour plot active, copy and paste the script to the Script Window (see Window menu), then highlight the entire scriot and press Enter.

Hi:
Origin 7.5 doesn't support such contour plot. In Origin 8.0, we have made some improvement and you can directly plot a contour from worksheet data, without gridding. This kind of contour graph supports user-defined boundary and cylindrical coordinates. For example:
You can download an demo on our website to evaluate this new feature.
Thanks
