我就是这样做的。我正在使用 ASP.Net MVC,但您可以使用任何框架或语言。
values、legendvalues 和 sectorLinkValues 是在页面中创建的 .Net List 对象。
%>
<script type="text/javascript">
$(document).ready(function () {
<% =truViewPOC.Helpers.GraphaelChartHelper.GetJavaScript(100, 150, 90, title, values, legendValues, sectorLinkValues, null) %>
});
这是我的 GetJavaScript 方法:
StringBuilder javaScriptBuilder = new StringBuilder();
javaScriptBuilder.Append("window.onload = function () {var r = Raphael('holder');");
AppendCenterCoordinates(ref javaScriptBuilder);
AppendLegendInfo(ref javaScriptBuilder, title);
AppendPieChartInfo(ref javaScriptBuilder, xCoord, YCoord,radius, values, legendValues,sectorLinkValues);
AppendFunctionInfo(ref javaScriptBuilder);
javaScriptBuilder.Append("}");
private static void AppendFunctionInfo(ref StringBuilder javaScriptBuilder)
{
javaScriptBuilder.Append("pie.hover(function () {this.sector.stop();this.sector.scale(1.1, 1.1, this.cx, this.cy);if (this.label) {this.label[0].stop();this.label[0].scale(1.5);this.label[1].attr({ 'font-weight': 800 });}}, function () {this.sector.animate({ scale: [1, 1, this.cx, this.cy] }, 500, 'bounce');if (this.label) {this.label[0].animate({ scale: 1 }, 500, 'bounce');this.label[1].attr({ 'font-weight': 400 });}}); ");
javaScriptBuilder.Append("pie.each(function(){ this.sector.label=this.sector.value; })");
}
private static void AppendPieChartInfo(ref StringBuilder javaScriptBuilder, int xCoord, int YCoord, int radius, List<decimal> values, List<string> legendValues, List<string> sectorLinkValues)
{
javaScriptBuilder.AppendFormat("var pie = r.g.piechart({0},{1},{2},{3},", xCoord, YCoord, radius, ConvertValuesToString(values));
javaScriptBuilder.Append("{");
javaScriptBuilder.AppendFormat("legend: {0}, legendpos: 'east', href:{1}",ConvertValuesToString(legendValues),ConvertValuesToString(sectorLinkValues));
javaScriptBuilder.Append("});");
}
private static void AppendLegendInfo(ref StringBuilder javaScriptBuilder, string title)
{
javaScriptBuilder.Append("r.g.text(140, 24, " + "'" + title + "'" + ").attr({ 'font-size': 16 });");
}
private static string ConvertValuesToString(List<decimal> values)
{
string finalString = "[";
for (int i = 0; i < values.Count; i++)
{
finalString += values[i].ToString();
if (i<values.Count-1)
{
finalString+= ",";
}
}
finalString += "]";
return finalString;
希望这会有所帮助。如果您对此代码有任何疑问,请告诉我。谢谢。维卡斯}
