Calib Curve Plot by compound

Hello,

Filter the outer group by something like the example below. You might also be able to use calibration type or some other value in the filter. In the example below, Peak B was not calibrated, and thus did not display in the report.

Perfect! I will try that. Thank you very much. 

I worked perfectly when I ask coefficient a to be more than zero. thank you again! 

I would note that this will only work when "a" is greater than zero, meaning if you have an "a" that is negative it will also filter out those. If you are only using linear curves for calibrations that you expect to be positive correlations, then you should be fine. If not, then you should consider changing it to something like "len(cstr(CalibCurve_A_Coefficient)) > 0", which has worked in the past for me when I want to detect whether or not an internal variable has been set.

Oh thank you for your help. I will surely try it. Can you explain me a little more about the programming function of len and cstr? Thank you again for your precious help and advice. 

Hello,

You can search online for VB functions len and cstr for more detailed information if you need to as the expressions in IR are VB based. In the example, provided by ColeFunk the CalibCurve_A_Coefficient value was converted to a sting and then the length was determined. This would only be needed only if the value of the field could be negative. In this example, any non null value in that field will have a length > 0 and thus meet the filter limits. You could likely also use field <> 0 as well or a Vb is null or empty test as another alternative. 

Len() - returns the length of a string.  

Cstr() - converts the data type to a string.
