Labels in Barchart are displayed infrequently

We use a couple of simple bar charts in our App. For some bars, the labels are not displayed. How can I ensure that I always see the complete labels of my series

It turned out that we don’t have enough space for our charts and if we allow to make it larger, all labels appear

Other ideas were to force the labels to be displayed every time (using some dirty CSS hacks) or try to increase the space between the grey and green bar (if possible).
Thanks @nasir.ahmad for your ideas!
