I have such type of line graph where extra space is coming along X axis after Feb'18.
I want the line to end at Feb'18 and remove the extra one. I have tried some options in Graph Properties to do so, but not able to achieve this yet.
Can anyone please help me regarding the same?
Do you mean the space between X axis and Feb'18? That should be dependent on the value of Feb'18 for yellow line. My guess is the red dot is from another value that has only 1 value in Feb'18. Put the values in a table, you will see it.
