Can we draw a line between two values that are from different months and there are no continuous dates between them?
Yes, this can be achieved with the help of a line chart. Usually, what happens when you drag these Dimensions & Measures into the self, Tableau will automatically select the best chart for your data. All you have to do over here is go to the March self and from the chart type, select the line chart. by default, it will be selected as automatic.
