Show full prediction time series, not just tomorrow onwards

[jaryaman]

Plots like this don't look too great (Italy)

This is happening because the trend for the most recent few days don't quite fit the history. The model weights every data point equally, whereas plots like this beg us to give a higher weight to today's data.

If we show the full prediction time series, especially on a log scale, the eye is more forgiving, and more closely reflects what's going on under the hood with our predictions.

Suggestion: When toggling "show predictions", show:

• The full predicted time series (including past values)
• Default to showing on a log scale
