I assume the following points to solve your issue,
a) Plan is computed as Running Total ( Data availabnle in database like Cummulative Sales Volume).
b) Actual Values are Day/ Month wise.
1) Drag both measures onto the Row shelf and Dimensions onto Column shelf.
2) And If you want to create a Running Sum of Actual Value, Right Click on that select "Quick Table Calculation" then select "Running Total".
3) Right click on second measure on the view, then select "Dualk Axis".
I hope, now you will get expected visulization.
Thanks a lot for your reply.
But this doesn't answer my question.
Please see the attached snap shot in which the blue area chart I have to limit it wrt to today's date.
Once you create calculated fields & place them on the view then you can take the Area Chart, Line Chart combination to get your desired VIZ.
