Impossible to read the data on charts

[epodivilov]

In the case of small values, there is no way to see these values on the graphs. There is no caption on the charts, since it does not fit, and the tooltip that appears is out of the screen.

Thanks, I'll see if I can improve this.

It seems, that is a problem of Nivo.
