Chart Axis With a Filter

Hi,

I have 7 charts (One for each day of week) and I have put a filter on each chart to show that respective days data.

However I want the Y axis Value to remain the same for each day and i want this value to be the Maximum Value of the entire dataset.

How can I do this.

I have a field called MAX_AXIS but this is only showing me the max axis for that day not the week because of the filter

Thanks
