You have shared only one node (an http request). Please select the charts and export those. Rather than attaching a file please paste the flow text here. In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)
```
code goes here
```
See this post for more details - How to share code or flow json
Also tell us how many lines are on each chart and what rate they are updated.
Have you worked out the total number of data points that the charts will hold once the charts are all full?
