hello,

i found a strange behaviour. I import some data into a worksheet. then i run a origin c function, which creates a new worksheet, lets say wks2. There it copies some columns from the first worksheet and also creates some new ones which are calculated using different columns of the first wks. finally it does some plots.

One of the calculated columns is calculated as follows:

Dataset dsXRMRQz(wks2,1);
wks2.Columns(1).SetName("qz");
double faktor = 0.001013546246585;
dsXRMRQz=faktor*energy*sin(dsAbsTheta*Pi/180);


energy is set to a value before that call. dsAbsTheta is a Dataset from an column of the first worksheet.

If I run the function, it calculates well the value of the first row. But not the rest! if I run the function a second time it calculates all rows correct. I don't know why :(

The second worksheet is created as follows:
	//neues Worksheet zum Arbeiten
	Worksheet wks2;
	wks2.Create();
	wks2.GetPage().Rename("XRMR");


Also if i want to plot a column manually from this second Worksheet it doesn't work. I think this is a different problem ...

Can someone help me??

Thanks in advance

greetings

bubbas

no possibility ??

okey, sorry seems this time it wasn't related to the problem above ..

fixed it creating a column containing sin(...) and then using the Dataset of this column.

now i have to calculate the following:

dsT2TSSAbs_AbsTheta=1.0/(sin(dsAbsTheta*Pi/180)*xi/mu+1);

dsT2TSSAbs_AbsTheta and dsAbsTheta Datasets. I have the same problem ...

thx

oh okey ;)

it works now changing the order!

Thanks!

Hi bubbas,

We could reproduce the bug - thank you for reporting this.
For now, changing the order of the computation in your statement, such as:
dsXRMRQz=sin(dsAbsTheta*Pi/180)*faktor*energy;
seems to fix the problem.
