Address line chart "cut-off" when using the logarithmic scale
When changing a chart's setting to use the logarithmic scale instead, the user might notice that their line chart may "cut-off" and no longer display zeroes or negative numbers anymore. For example, Figure 1 shows a Line Chart with 'Line B' that has apparently been cut off:
This is by design and expected behavior. Mathematically speaking, the log of zero or a negative number is undefined. Thus, Zoomdata will skip zeros and negative numbers when a logarithmic scale is used.
