dotp label

Is there a way to turn off the dotp labeling of chromatographic peaks? For my dataset, it appears that some XICs have a dotp label along with the mass accuracy and retention time labels, but others do not. Please see attached slide.

On the chromatogram graph, Skyline only displays dot products that are greater than 0.5.
Also (not applicable to your screenshot), for peaks other than that currently chosen peak, Skyline only displays dot products which are better than the dot product of the currently chosen peak.

Thank you for the quick response. What I am asking is if there is a way to turn off the dotp labels. I am preparing a figure for a manuscript and would like to remove it.

But, Skyline also only shows the dotp values on the selected peak when there is at least one other peak in the chromatograms with a better dotp value. Hard to imagine where such a peak would be in the plots you have chosen. Perhaps down in the lower intensity data somewhere? It looks like you may also have turned off the retention time labels for all but the best peak and the integration boundary dashed vertical lines.

I can't see an option to turn this off. Sorry. We can add one.

Do you know about the "Copy Metafile" right-click menu item? You can paste that metafile into PowerPoint, then convert it to a Microsoft Drawing object, and then you will probably be able to delete the dotp things.

(There's also "Copy Data" where you can paste the data into Excel and then plot the chromatogram as a scatter plot).
