I used Rob Bovey's xy chart labeler to label a dataseries in a scatterplot. Each datalabel refers to a cell in the worksheet, such as "=BE_Cat!$D$30", so the data label contains whatever is in cell d30, d31 etc.
Unfortunately, I (or Excel) screwed up and have many, many files and charts where the label formula refers to the wrong sheet, e.g. "=CV_Cat!$D$30" instead of "=BE_Cat!$D$30".
To fix this, I'm looking for a macro to select a certain dataseries in a chart (Let's call it "CV"), and then circle through all the data labels in the series to change "CV" to "BE" in the label formula, i.e. from "=CV_Cat!$D$30" to "=BE_Cat!$D$30", "=CV_Cat!$D$31" to "=BE_Cat!$D$31", and so on.
