Summary

Instead of throwing errors or warnings, if the user is using a log scale with a dataset with 0
values, we will hide them on the rendering of line and area charts.

Screenshot 2019-03-22 at 19 38 28

This fix also the defined area of a line/area chart: if the y value is null, the area/line is depicted with an empty space between the previous non null value and the following one.

fix #112, fix #63

Since this logic is repeated in a few places, could create a helper function isLogScale(type: ScaleType) to ensure consistency.
