Hello,

I want to be able to change the color of the pie and to make the lines of the slices visible and the data label of each slice, how can i do them? in qlik sense i can only edit the color of the selected slice i want to change the color of the pie it self.

Thanks

I've made you a demo here that has buttons that change the colors and the labels. In essence, you just set the new data on the chart and then call the RGraph.redraw() method.

There's also a button that changes the data.
