Too many charts and too wide of screen for an HMI design. If you need all of the charts, then look at a Tab control to separate the views. However the charts will require a ton of memory.
I think you need to look at how you are going to acquire your data first. Then process it. Then display it. How much data will be measured and how much will be calculated?? If it is all measured, then look at using clusters to combine similar readings. Voltage phases in one cluster, Current in another cluster...
How long will the calculations take on the measured data?? Is the processing slower than the sample rate. Then you will need a queue to buffer the data until it is all processed.
If you can read the data, make some calculations, then store it all in a big array or database?? It may be easier to acquire the data, write it to a database, then query what you want to display out of the database. If the data structure doesn't use a ton of memory, you may be able to use a LV2 functional global to hold the data. The functional global controls writing data into the buffer and what is read from the buffer.
