Loader Inconsistency in unit labels

[butler]

some loaders give units in latex ([A^{{-1}] … ) while others give it in straight text 1/A. DataInfo? displays text directly using texctrl box but same value is passed to the xaxis ans yaxis labels of the matplotlib graphs which really works better as LaTex?. Should be consistant, preferably in a way that works well for both DataInfo? display and the graph display}
