@Lux6 I see your point that how could the graph count for a single month could be higher than the total of the filtered values of the freeform table.
It looks like the line chart is plotted using the grand total i.e. 11.15M and not the filtered total as you'd expect. For that matter other trend type visualizations like Area and Area Stacked are also behaving in that manner. I'm assuming when you run a trended visualization on a ranked report it uses the grand totals for plotting the graph.
While I don't have the clear explanation for why the graphs behave this way I believe you can use the suggestion from my comment below to avoid the work of exporting the data to excel for accurate charting, you can achieve the correct charting based on the filtered totals if you convert your dimension level filters to a segment and use it either on panel or in freeform table against the metrics.
So instead of doing this,

do this,

or this,
