Top of the plot gets cut off

[sayadennis]

Hello! Thank you for building this awesome package.

I'm trying to visualize some odds-ratios and their confidence intervals, and I'm running into an issue where the top of the plot seems to get cut off.

I installed forestplot today via conda with conda install -c conda-forge forestplot, and am running it on Python 3.9.6.

Data

>>> df
  varname        or       low      high
0       a  1.761471  0.926563  3.022285
1       b  1.443660  0.517059  3.130794
2       c  1.525227  0.603459  3.082003
3       d  0.895682  0.463703  1.660016
4       e  4.025670  1.196941  8.932753
5       f  1.086105  0.555171  2.045735

Plotting code

fp.forestplot(df,  # the dataframe with results data
    estimate='or',  # col containing estimated effect size 
    ll='low', hl='high',  # columns containing conf. int. lower and higher limits
    varlabel='varname',  # column containing variable label
    ylabel='Confidence interval',  # y-label title
    xlabel='Odds Ratio',  # x-label title
    color_alt_rows=True,
    figsize=(4,8),
    **{
        'xline' : 1.,
        "xlinestyle": (0, (10, 5)),  # long dash for x-reference line 
    }
)

plt.savefig('test_forest_plot.png', bbox_inches='tight')

What I'm seeing is the attached image, where the top of the plot (where variable "a" should be) is getting cut off. I've tried adjusting the plot size but the issue persists. Any insight or advice would be appreciated!

Hi, I also had the same problem. Have you gotten the answer on how to solve it

Hi @sayadennis, thank you for raising this issue.

A quick solution is to adjust the ylim using ax.set_ylim(0, 5.5) (@Chloe-Hao adjust 5.5 accordingly based on how many rows you have):

ax = fp.forestplot(df,  # the dataframe with results data
    estimate='or',  # col containing estimated effect size 
    ll='low', hl='high',  # columns containing conf. int. lower and higher limits
    varlabel='varname',  # column containing variable label
    ylabel='Confidence interval',  # y-label title
    xlabel='Odds Ratio',  # x-label title
    color_alt_rows=True,
    figsize=(4,8),
    **{
        'xline' : 1.,
        "xlinestyle": (0, (10, 5)),  # long dash for x-reference line 
    }
)
ax.set_ylim(0, 5.5)
plt.savefig('test_forest_plot.png', bbox_inches='tight')

This seems to be a non-issue in v0.2.0. I'll fix this in the next patch.

@LSYS This solves the issue, thanks! I appreciate the prompt response.
