Dummy it up.

Either add a textbox that contains a zero and position it appropriately

or add a dummy series that contains the desired values and show its
datalabels. For an example that you can adapt, see

I have an unconventional y-axis, with values of 2, 7, 12, 17 and 23 on my
y-axis in my chart. This was used to bring out the importance of the data.

However I now wish to have the y-axis show a 0 too, how do I do that while
keeping my unconventional axis values?

Would appreciate any help! Thank you! :)
