图例和条形图颜色不匹配 [英] Legend and Bar Chart Colors do not match

问题描述

我有以下实现，我使用colorField来指定颜色。但是，即使我正确地为条形图堆栈对象着色，但此颜色与图例颜色不匹配。我认为它应该以某种方式绑定，我应该如何解决它？

I have the following implementation and I used colorField to assign colors. However, even though I color the bar stack objects properly, but this color does not match with legend color. I thought it should be binded somehow, how should I fix it?

我使用了 colorField ，因为我想要为条形堆栈列中的配对对象指定相同的颜色。

I have used colorField, because I want to assign same color for paired objects in bar stack column.

dataSample：

dataSample:

data[0] = {
    "value": 29,
    "series": 1,
    "category": "Men",
    "fname": "NY",
    "valueColor": "black"
},

推荐答案

这是一个解决方案，虽然它有点像hacky。

Here is a solution, although it feels kind of hacky.

我使用legend.item.visual重绘图例并从数据中拉入valueColor，很好地传递给了legened.item.visual功能离开。

I used legend.item.visual to redraw the legend and pulled in the valueColor from the data, which was nicely passed along to the legened.item.visual function.

legend: {
        item: {
            visual: function (e) {

                var color = ""

                for (var i=0;i<e.series.data.length;i++){
                    if (e.series.data[i].valueColor != "" && e.series.data[i].fname != "") {
                    color = e.series.data[i].valueColor
                    }
                }

              var rect = new kendo.geometry.Rect([0, 0], [100, 50]);
              var layout = new kendo.drawing.Layout(rect, {
                spacing: 5,
                alignItems: "center"
              });

              var marker = new kendo.drawing.Path({
                fill: {
                  color: color
                }
              }).moveTo(10, 0).lineTo(10, 10).lineTo(0, 10).lineTo(0,0).close();

              var label = new kendo.drawing.Text(e.series.name, [0, 0], {
                fill: {
                  color: "black"
                }
              });

              layout.append(marker, label);
              layout.reflow()

              return layout;
            }
         }
     },
