Highcharts, How can I change the datalable distance in a pie chart based on the value

由 天大地大妈咪最大 提交于 2019-12-23 12:44:10
问题 I am using Highcharts Pie Chart. The chart has a few large wedges and then several smaller wedges. I can use the distance to pull the datalabel into the wedge or have it outside the pie, but I want a mix. I want the fat wedges to have the label in the pie, but the tiny wedges I want the label outside. I can change the color of the label in the formatter function based on the value (this uses a span style="color:'+color'"). I tried adding distance to this span but it doesn't work. Can anyone

问题 I have a bar chart which shows different categories on the Y axis. I can change the color of all of them on the axis at the same time by using: chart.ChartAreas["MyChart"].AxisY.LabelStyle.ForeColor = "Red"; However it doesn't allow me to set the color for each of them. Any help will be much appreciated. 回答1: You can try adding custom labels to the chart, and that will allow you to modify each one individually. private void AddCustomLabelAtYValue(double YValue, string Text, Color ForeColor) {
