I have been exploring the use of the awesome statistical-charts module. So first of all, a big thanks to the authors of the same.

I seem to have hit a snag when it comes to handling of -ve values. In my example (attached tex & pdf), the y-axis labels and the grids do not seem to be working on the -ve side (also, able to flip labels above x-axis for -ve values). This seems to be the case of column charts and bar charts (and I will test this for the other types of charts also).

If this is a more generic issue across all the types, then I can contribute towards enhancing it (as any charts module should handle -ve values). Any tips or pointers would be really helpful.

Thank you very much.

best regards,
