Use results from formula in CR Chart

Posted on 2008-06-20

Hi,

I can't find how to use the result of a formula field in Crystal Report in Crystal Report Chart. I can only use summary fields, or the database fields as data for the chart.
The formula field is needed, as it first recalculates the data.

Is there any way to use the result of the formula in a chart?
Thanks
Karl

The formulas can be used but not all the formulas. If your formula is using printtime functions then you cannot do the charting based on those formulas directly though you can circumvent such problems with some kind of workarounds.
What is your formula doing? Can you post the formula?

The code for RecalculatePerCourse

EvaluateAfter (GroupName ({Courses.course}))
formula = {#TotalPointPerCourse}/{#TotalMaximumPerCourse}*{CoursesInGroups.maximum}
'(this formula recalculates the results of exams per student per course)

Then another formula Counts up the results of this formula per maincourse
WhilePrintingRecords;
NumberVar totalPointPerMainCourse;
NumberVar totalAveragePerMainCourse;

totalPointPerMainCourse := totalPointPerMainCourse + {@RecalcPointPerCourse};

This value (totalPointPerMainCourse) is what I need

These two formula's are just a bit of whole project. I'm quite new to CR, but with a lot of patcience (and maybe luck) a found the way to make a -for me- complex report.
It is impossible to post the complete report and database structure. Hopefully you can give me an answer after this post...

Thanks for the help,
Karl

These formulas are using print time functions like evaluate after and whileprintingrecords for which you cannot create charts/crosstabs directly. Because the formulas are evaluated in later passes aftter charts/crosstabs are evaluated.

Here is link to an article which discusses the method to create charts in such situations. I was able to successfully do it following the method discussed in the article
