Line chart does not allow display of very small values

[kaimikael]

Timeseries version

0.5.1

Orange version

3.34.0

Expected behavior

In the attached workflow I have both a Line plot and a Line chart. They are fed with data where the y value is fairly small (on the order of 10⁻⁵–10⁻⁶). I expect the two widgets to show much the same display.

Actual behavior

The Line plot scales to the relevant range and shows the variations, whereas the Line chart shows the data as flat lines and cannot be rescaled.

Steps to reproduce the behavior

Load the attached workflow, check the two widgets named “Murders/capita over time”. Note that the Line chart version insists that all values are 0.
