charts

问题 I have this pie chart: http://jsfiddle.net/gXjVY/ And as you can see, the data labels of the charts are overlapping. I tried to define the distance: -1 inside a serie, but it doesn't work. Anybody an idea, how I can define different positions, or distances for the series? 回答1: You can set for series, not for a point, different distances, see: http://jsfiddle.net/gXjVY/3/ series: [{ data: [...], dataLabels: { distance: -30 } }] 来源： https://stackoverflow.com/questions/16295279/highcharts-pie

问题 Im trying to use the MPAndroidChart library to develop a circular chart. But only Pie chart is available. So i tried giving two xvalue coordinates, with one color similar to background. So i got something similar to circular chart. But i'm not able to change the background color and font color of center text inside the pie chart? Thanks! 回答1: There are two possible solutions: Retrieve the Paint object used by the chart to draw the "center-hole" and modify it the way you want Paint p1 = mChart

问题 I'm using charts.js . This is my chart: I have 3 or more datasets in the same chart, each with a different scale, let's image that all the scales are on the left. As default when deactivating a dataset (for example in this case clicking on "Sold Products") the scale is rescaled between [-1, +1] as here on multi-axis demo code too. Is there a way in which I can make disappear the dataset's scale when that dataset is deactivated? For example in this case if I deactivate "Sold Products", I would

Indeed, pie does not return any value so you don't know where
