Origin 7.6 SR6
Operating System: Vista
Hi,

I asked in this forum a few days ago about how to change the name of a graph to the name of the column. Sometimes I need to fit the same data with different models and compare them. So I want to append a "_2" after the name of the column to name the new graph. I tried strcat and it didn't work. I cannot give the name of the column,which is a string, to a character array. Anyone knows how to solve this problem? Thanks a lot.

Best
Yu

Hi, Yu:

I suggest that you use Origin string object to construct a new name in this case. Please refer to the following code:

void str_cat()
{
	string strColName = "A";
	
	strColName = strColName + "_2"; //no need to use strcat here.
	
	GraphPage gp;
	gp.Create("Origin");
	gp.Rename(strColName);
	
	return;
}

Hi,

In Origin C, you can:

int n = 2;
string str = "abc_" + n;

Or

string str;
int n = 2;
str.Format("%s_%d", "abc", n);
