Interactive scalar_global_heatmap, query error if inc value set too small.

[colm-brandon-ul]

How the querying interaction works for scalar_global_heatmap (i.e. click on a patch in the heatmap and see the exp_hist for that step/layer/tensor type), it gets the query parameters from the axis tick labels.

However if the value for inc is set too small and matplotlib hides some tick markers (i.e. only displays major tick labels) this breaks the querying process. It can result in an out of range error or the wrong parameters being inserted into the query.

viz.interactive(
    f= viz.scalar_global_heatmap,
    df=df,
    tt='Activation',
    col_wrap = 3,
    scalar_metric='rm2',
    inc=50
)

Perhaps need to redesign how this occurs.
