Graph showing just Monday dates

[mbarnes106]

I have some basic data produced weekly.

I want to do a time series chart to show change over time but it puts every day of the week in the graph.

I do not want to look at ISO week numbers as my  business has different week numbers so that will be confusing (our week 33 is ISO wk24) but is there a way to create a graph just showing dates I have in my data
