A label on the top of bar re-appeared when it's exported!
Posted: Wed Aug 03, 2005 7:34 am
Hello,
I have a bar graph. What I tried to accomplish is to show the labels only for the max and min value and hide the labels in-between. Please have a look at the following diagrams.
figure1. when a chart is created from the data.
figure2. when the chart is exported to a meta-file.
I also attach the sample of my code.
I wish the matter to be solved as soon as possible since there are customers waiting for this to be sorted out.

Many thanks.

Code: Select all

//sprintf(maxBuf, "%f", maxVal);
//sprintf(minBuf, "%f", minVal);
_gcvt( maxVal, 10, maxBuf );
_gcvt( minVal, 10, minBuf );
CString tmpStr = _T("");
tmpStr = *MarkText;
CComBSTR tmpBSTR = tmpStr;
double markVal = atof(tmpStr);
CComBSTR emptyStr = _T("");
*MarkText = emptyStr.Copy();
CString str = _T("");

if ( markVal == maxVal )
{
len = strlen(maxBuf)-1;
str = maxBuf[len];
if(str == _T("."))
maxBuf[len] = '\0';
tmpBSTR = maxBuf;

str = minBuf[len];
if(str == _T("."))
minBuf[len] = '\0';
tmpBSTR = minBuf;
*MarkText = tmpBSTR.Copy();
}
}
else if ( showmode == 2 ) {
CString sName = _T("");
sName = Series(SeriesIndex).GetTitle();
CComBSTR tmpBSTR = sName;
*MarkText = tmpBSTR.Copy();
}
}
