I am working with bokeh library in python to generate charts like bar chart , histogram , line chart for visualization of data.
Our code was developed in bokeh version 1.4.0. Now, I want to upgrade the bokeh version to 2.4.3 but, here the issue is when we are upgrading the code the chart is not getting generated….
We found the function SERVER_DOCUMENT() response in 1.4.0 was something like this as shown below……….
<script src=http://localhost:5004/histogram/autoload.js?bokeh-autoload-element=1094&bokeh-app-path=/histogram&bokeh-absolute-url=http://localhost:5004/histogram id="1094"></script>
Whereas, in 2.4.3 the SERVER_DOCUMENT() response is …….
<script id="1002">
(function() {
const xhr = new XMLHttpRequest()
xhr.responseType = 'blob';
xhr.open('GET', http://localhost:5004/histogram/autoload.js?bokeh-autoload-element=1002&bokeh-app-path=/histogram&bokeh-absolute-url=http://localhost:5004/histogram, true);
xhr.onload = function (event) {
const script = document.createElement('script');
const src = URL.createObjectURL(event.target.response);
script.src = src;
document.body.appendChild(script);
};
xhr.send();
})();
</script>
Previously, the server used to trigger “/histogram” endpoint but, in recent response the server is not triggering…
Attempts we tried but, failed to trigger the “/histogram” endpoint.. For bokeh 1.4.0 server is defined as
Server({'/histogram': histogram_doc},extra_patterns=[('/', ChartHandler)], allow_websocket_origin=["localhost:2502"],port=5004)
Now, for bokeh 2.4.3 server is defined as…
Server({'/histogram': histogram_doc},extra_patterns=[('/', ChartHandler)], allow_websocket_origin=["localhost:2502"],port=5004,use_xheaders=True)
We are expecting to trigger this endpoint.. Please share your thoughts…. To resolve the issue…
