> Type 'scatter' works as expected though Nice catch!! I even hadn't thought myself about comparing performance to the scatter chart. Could you then please add the label "_bug_" to this issue then, so hopefully somebody ever finds some time to have a look a it? It would be a really nice improvement for our (open-source Node-RED) dashboard, because this is a typical use case for our users. Thanks!! > See also my Demo in related https://github.com/apache/echarts/issues/18742, Yes you correct, that looks very smooth. And you even use `setOption` instead of `appendData`, which kind of surprises me that this works so well: because in my tests the `setOption` was horrible slow compared to `appendData`. I thought it was because Echarts then need to calculate the delta itself, so it has to compare all the datapoints to figure out at the end that only a single datapoint has been appended. But perhaps I am completely misunderstanding the entire concept then... > You may consider collecting new data and appending it only once within your preferred interval. Just like this demo. @Justin-ZS Thanks for joining here! Aah, why didn't think about that myself... Yes your demo contains a decent workaround. That way our application is in control of when the re-rendering needs to happen. Nice one! I am certainly going to use this as a workaround. Although it would be still nice if some day somebody could fix the original refresh issue... -- This is an automated message from the Apache Git Service.
