Until a few days ago, I didn't think there was any way of altering your source
data cells once you'd created a chart. I've now worked out that if you
single-click on the chart, then you can right-click on the chart to get "Modify
Data Range", but if you double-click and go into the chart editing mode and then
right-click, the option is nowhere to be seen, in spite of plenty of related
options being available, such as changing the chart type. I would have expected
all these options to be together in one place, and if this confused me, it's
going to confuse Openoffice newbies even more. This is a minor issue, but it is
minor issues such as these that cause prospective Openoffice users to give up
after one attempt claiming it's too difficult.
