Missing information from x axis in some visualizations

[efotopoulou]

at the bar charts the horizontal axis parameters are missing. while by hovering the mouser over the bars one can get the info , if someone wants to download the image, he misses a lot of necessary information from the x axis.

same happens with pie charts.

Same issue from my side too: The GDP Growth Rate of Greece "dataset/query" has values from 1962-2013 but only a subset is depicted... 1969-1982 - How is this subset selected and why is this happening?
