I am trying to use this template to create a bar chart for time data, preferably with a larger spacing when dates are further apart. But I don't quite get what I am supposed to input. Apparently, it's not
{{Graph:Chart|width=400|height=100|xAxisTitle=X|yAxisTitle=Y |type=rect|x=1900, 1930, 2020|y=100, 100, 100|xType=date|scale=year|xAxisFormat=%Y}}
?
