"ValueError: 'xerr' must not contain negative values." about forestplot HOT 5 OPEN

Re: "ValueError: 'xerr' must not contain negative values."

I just experienced this when my ll and hl were reversed. So you might check that.

from forestplot.

In Feature A, D, E, "Hazard Ratio" and "2.5%" look to be identical, and in Feature F and G, "Hazard Ratio" and "97.5%" are identical. What happens if you remove those and rerun the data?

If that fixes the problem, then you may need to fudge the 2.5% values or 97.5% values to make the lower limits slightly lower than the Hazard Ratios or the higher limits slightly higher.

@Aleksandra130501 do you have minimal code and data example i can use to reproduce your error?

from forestplot.

Okay, it looks like this error was reported a while ago but hasn't been addressed yet. I am encountering the same issue, and here is my data to reproduce the error:

Here is my code:

import forestplot as fp

# "forest" below is the above data frame.

fp.forestplot(
    forest,
    estimate="Hazard Ratio",
    ll="2.5%",
    hl="97.5%",
    varlabel="Feature",
    sort=True,
    pval="P-Value",
    annote=["est_ci"],
    annoteheaders=["Hazard Ratio (95% Conf. Int.)"],
    rightannote=["formatted_pval"],
    right_annoteheaders=["P-Value"],
    xlabel="Hazard Ratio",
    table=True,
)

Here is the error message:

ValueError: 'xerr' must not contain negative values

@jdoiii good catch. @liberaliscomputing Please try that. I had a similar issue when the estimate was (erroneously) higher/lower than the upper/lower confidence limits.
