changing labels of a bar chart to display other data

[TtNl]

Edit to combine two similar (I think) questions. Workbook small update.

Trying to have the labels of a bar chart show other data than the data used to build the chart.

I have 15 "steps" on the horizontal axis. The data used is a number, so for example the first bar (A) has a value of 5 so this would be a bar 1/3 full. I cannot change the data used.

1) Looking to change the labels of the horizontal axis from the numbers 1-15 to something else, for example "name1-name15".

2) Looking to change the data labels inside the bar chart to yet another data set that has dates. For example the first bar (A) has an attached date of 30/jun, so I would like to show 30/jun inside the bar chart as a data label.

Are these possible? I may be using the wrong chart/graph/tool to show what I want to show, if so please tell me where to look.

Thanks a lot!
