Making a Timeline

As you can see, the technique works well. I've shown how you may insert more than one range on a timeline. Also verified that you may use dates. :-)

Hi Jim,

Here's your data, rearranged on the table, with some added columns, presented as a scatter chart, with connected pairs of data controlling the beginning and end of each 'life line.'

The numbers in the yellow columns are the y values for each x,y pair. They control the height of the line above the base line.

The names and symbols on the left are the Legend of the chart, automatically generated, but forced into a vertical stack by decreasing the width of the text box Numbers generated to hold this information.

The Legend was repositioned to the left of the chart, and Show Y-axis labels was unchecked in the Yaxis options.

Numbers offers no control over spacing of the list in the legend, so the chart was shortened top to bottom to fit the existing line spacing of the Legend.

Regards,

Barry
