    Pie-chart legend problems Posts

    Hi there,

    Upon creating a pie chart, I’m trying to set the legend to display vertically next to the pie chart:
    legendLayout: { left: 225, top: 60, width: 50, height: 500, padding:5, flow: ‘vertical’ },

    However, the chart data is very dynamic and can be a huge list of data or a few entries. The problem this causes, is that the legend items fill a new column when reaching the height of the grid. This causes padding issues with the legend items.

    My question is: Is there any way to change the chart to:

    i) Display the top 5/10 legend items, or
    ii) Apply padding to the legend items, or
    iii) Prevent the legend from creating a new column of items when the items has reached the height of the grid.

    Your swift correspondence will be highly appreciated.

    Hello diekwagga,

    By modifying legendLayout, padding and the chart div’s width and height, you can fully customize the chart and its legends layout. For example:
