Vertical Axis in Pivot Line Chart Is not Tally

test1.png

I based on simple data to create a pivot line chart.
However my estimate line value dated 22/7/19 is 200 (1st point) but it located in between vertical axis value between 350 to 400.

Is there any mistake i make caused the line chart like that??
How to correct it?

Thanks.

I don't know why this is a common mistake, but it looks like you have chosen a stacked line chart, when you intended to ues a regular line chart (173+200 isabout 373, which is close to where the point is plotted). If you change your chart type to line instead of stacked line, you shouyld get what you want.
