I have an issue with a chart. The dimension is a cycle group, and on 'Country', the legend takes a lot of space from the chart. It is any possibility to 'minimize' the legend, or to create a drop-down menu with those ?
to my knowledge there is no possibility. You can change the size of the space reserved for the legend (by hitting Ctrl+Sh inside the charting area) but I think you cannot minimize it - not like that anyway.
What you can do is, you can deactivate the legend and just create the same list yourself, along with the colours - a bit of work of course, but you can create a listbox with the colours alongside the labels for ex. And then you can design that any way you want.
Press the CTRL and SHIFT keys at the same time. You'll see red outlines around the chart elements like the legend. You can then resize the legend. You can also disable the legend and use a multibox and add the cycle group to it. Users can then use the multibox to select items.
