[Bug] /economy/macro plotting series together doesn't work if one has daily data

[JerBouma]

The 10-year Government Bond yield of United Kingdom is depicted daily. This is not the case for Germany and France. Thus, plotting these together will not work. It completely takes out the lines for Germany and France.

Reproduce with the following code: macro --parameters Y10YD --countries France,Germany,United_Kingdom -s 2017-01-01 whereas this works fine macro --parameters Y10YD --countries France,Germany -s 2017-01-01 and this does as well macro --parameters Y10YD --countries United_Kingdom -s 2017-01-01. Raw data is also shown as NaN values.

Trying to fix this with plot only gives very odd results: plot --y1 china_Y10YD,united_states_Y10YD,united_kingdom_Y10YD --y2 germany_Y10YD,france_Y10YD,japan_Y10YD
