Hello, My chart is working perfectly, grabbing data from msSQL server every second, but the browser memory usage increases by 1Mb per second, causing the browser to crash after some hours. I have been looking at old posts from 2012-2015 showing workarounds, but I have not been able to implement them since I don't understand the explanations of the workarounds suggested. For example:
if (chart) {
chart.clearChart();
}
Is there a newer version of the API, then what do I need to change in my
code to migrate? If not can someone help me in how to make the workarounds
to work ?
I added some code below that shows the main parts I used. And attached a
screenshot, and one of the php script I use.
Thanks Nick
