How do I edit the data location for X-axis?

It used to be possible in previous versions without having to destroy the chart and start from scratch again.

I got “set first column” and “set first row” selected. I want A2:A400 as the X axis. not W7:W385

It seems the answer is to use Excel to fix that.

Perfectly possible.

The attached ODS (Calc) file has data for a Chart in the “barometer” tab & the actual chart in the “chart” tab. Take the following steps to get the screen as shown in the screenshot above:

  1. Switch to ‘chart’ tab
  2. Click mouse 3 times in short succession on the Chart
    (the screen switches to that shown above)
  3. Click on “Data Ranges” icon
    (top-line, near middle of line)
  4. Click in ‘Data range’ line of Dialog & change value
  5. Press OK when complete

I do this all the time to update after adding new values within the ‘barometer’ tab.
