How to add historical data in Real-time Line dynamically?

[tonyjin]

Hi All,

 

I provide the historical data when the chart has rendered for the first time. While the Real-time chart is running, I rewrite the XML file to add some new historical data. After rewrting, I refresh the web page.

 

And the problem happens, the chart displays the old historical data.

 

I guess that when the web page is refreshed the chart do not read the new historical data in the rewrited XML file.

 

 

 

Please let me know how to do in this case???

 

Thank you so much!

Hi,

 

 

 

Could you please try passing some random value to clear the cache as shown below?

 

 

 

myChart.setDataURL("Data Chart.xml?NoCache=some random timer value");

 

 

 

Hope this helps.
