'Discard extreme values' setting not sticking

User help

    I have a data point which sometimes returns wildly unwanted values, like -4296829.32.
    I must have enabled the 'discard extreme values' option a dozen times (and hit save!) but each time, it never seems to 'stick', and a few days later the nuisance values are still there.

    Any ideas? It is driving me nuts, not to mention screwing up all my graphs!

    What version of Mango are you using. I'm pretty sure this issue has been resolved in the latests 2.4.X release.

    2.1.0 - sounds like it is time to upgrade!

    Yeah, upgrading will fix that. I would recommend upgrading to 2.4.2 and you'll find quite a few improvements and bug fixes.

    Here is the link to get all the files and at the bottom of the page are the upgrade instructions:
