Tricky Horizontal Axis Display Issue Excel 2013

[DocM1066]

Hi,

I am creating a simple spreasheet for a medication dosing regime. The problem I am having with the horizontal axis labels are best explained in screenshots, but I cannot post those. Therefore the links

Click here for the data I need to display as 2 charts.
Click here for the display as chart. I like the display with the dates of the tests on the x-axis. However, if you look at it carefully you will see that Excel, which is pretty good in ignoring data labels in the chart itself, displays the data label in the axis and therefore gets the dates wrong.
If I take the data label out (click here)...
Then the whole display starts looking messy, (click here)
For the data chart I need to select the whole row, because if I only select the cells, not only is the chart display also messy, but I cannot add on any new test results / values.

Many thanks for your help

Hi, I have tried to change the label names, but it still shows the "doses" label in the horizontal axis. Not uploaded a screenshot as it's essentially the same as in the previous link. Sorry, but thank you very much for trying!
