如何将 Bokeh 与 Angular 4 集成？

2024-06-10

我在后端生成了散景图，我想将其嵌入到已经存在的 Angular 4 Web 应用程序中。 目前我使用了 bokeh.components 函数，它生成以下两个 html 标签。

<script type="text/javascript">
  (function() {
    var fn = function() {
      Bokeh.safely(function() {
        (function(root) {
          function embed_document(root) {

          var docs_json = '{"d199dc51-c663-4220-800f-a5f0d7c3a97a":{"roots":{"references":[{"attributes":{"bottom_units":"screen","fill_alpha":{"value":0.5},"fill_color":{"value":"lightgrey"},"left_units":"screen","level":"overlay","line_alpha":{"value":1.0},"line_color":{"value":"black"},"line_dash":[4,4],"line_width":{"value":2},"plot":null,"render_mode":"css","right_units":"screen","top_units":"screen"},"id":"f795b234-3b1e-4117-aa31-bccbbaaccf71","type":"BoxAnnotation"},{"attributes":{"axis_line_color":{"value":null},"formatter":{"id":"8c794376-5b4c-42f6-bcf4-662922d47df1","type":"BasicTickFormatter"},"major_tick_line_color":{"value":null},"minor_tick_line_color":{"value":null},"plot":{"id":"6fbff9b0-a4fc-4fc1-a50e-d34f906928b2","subtype":"Figure","type":"Plot"},"ticker":{"id":"5468ade8-3979-45b4-9dd0-fbb3cab5b888","type":"BasicTicker"},"visible":null},"id":"be01b966-482b-4e6f-8c6f-8bc0373791aa","type":"LinearAxis"},{"attributes":{},"id":"f9e57a1a-b5e1-4c3f-8e0d-4789dca393ec","type":"SaveTool"},{"attributes":{"fill_color":{"value":"#6C69EB"},"height":{"value":0.5},"right":{"field":"Sales"},"y":{"field":"ID"}},"id":"4dc67234-e29e-4e53-997c-3a6b2e40d5e5","type":"HBar"},{"attributes":{},"id":"db86af55-1185-4097-839a-8d5dc01f19a2","type":"LinearScale"},{"attributes":{},"id":"538fede7-868b-4740-a75e-cb6065ac1194","type":"ResetTool"},{"attributes":{"source":{"id":"946bc6d9-32c8-4dfe-8d34-a29c7c06a242","type":"ColumnDataSource"}},"id":"4ff758a6-c013-4e17-ae69-5c039b0c9394","type":"CDSView"},{"attributes":{"callback":null,"factors":["1348","1226","1306","1268","1103","1129","1340","1470","1783","1346","1264","1387","1775","1247","1771","1770","1773","1772","1190","1733","1727","1694","1584","1503","1113","404","403","401","509","1119","1653","1467","1677","1670","1565","1391","1699","995","1235","1314","1759","1218","1336","1553","1668","1134","1493","1742","1561","1501","1567","1676","1678","1251","1664","1056","1557","1753","1602","1288","1438","1657","1681","1604","1768","1105","1750","1009","1361","1666","1259","1766","1382"]},"id":"2949c368-f95d-4a48-addb-988e5d963ff9","type":"FactorRange"},{"attributes":{},"id":"925e5c0f-b284-4614-a702-33c0ee4bcf34","type":"WheelZoomTool"},{"attributes":{"grid_line_color":{"value":null},"plot":{"id":"6fbff9b0-a4fc-4fc1-a50e-d34f906928b2","subtype":"Figure","type":"Plot"},"ticker":{"id":"5468ade8-3979-45b4-9dd0-fbb3cab5b888","type":"BasicTicker"}},"id":"b1bd251f-e88f-46f1-ac91-5ab1d74ece4b","type":"Grid"},{"attributes":{},"id":"4f69bbc9-c6df-4c64-976c-9013fddff8db","type":"CategoricalTickFormatter"},{"attributes":{"callback":null,"tooltips":"\\n

也

<div class="bk-root">
    <div class="bk-plotdiv" id="74705daf-2fe7-47e6-9800-0ecaf72e9708"></div>
</div>

我可以将其嵌入到一个小样板中：

<!DOCTYPE html>
    <html lang="en">
        <head>
            <meta charset="utf-8">
            <title>Bokeh Scatter Plots</title>

            <link rel="stylesheet" href="http://cdn.bokeh.org/bokeh/release/bokeh-0.12.6.min.css" type="text/css" />
            <script type="text/javascript" src="http://cdn.bokeh.org/bokeh/release/bokeh-0.12.6.min.js"></script>

            <script type="text/javascript">
  (function() {
    var fn = function() {
      Bokeh.safely(function() {
        (function(root) {
          function embed_document(root) {

          var docs_json = <!---docs_json---!>
          var render_item = <!---items---!>

        </head>
        <body>
            <div class="bk-root">
        <div class="bk-plotdiv" id=<!--- div_id ---!>></div>
    </div>
        </body>
    </html>

为此，我需要从前两个脚本中解析出重要的变量（docs_json、render_id、div_id），然后使用 Flask 将它们作为 json 发送到前端。很像这样谷歌表格问题 https://groups.google.com/a/continuum.io/forum/#!topic/bokeh/McLDXP414ps

https://groups.google.com/a/continuum.io/forum/#!topic/bokeh/McLDXP414ps

有没有更好的方法将我的散景图发送到有角度的前端，而不必经历所有这些？
