I know this question has been asked before. I've used the charts.powerbi.tips to create a line chart with three Y-axis. But, the custom visual takes forever to load. Much longer than a line chart made within Power BI. The trends that I create for work, bacterial fermentation, involve 72 hours worth of data with 3 dependent variablesData points are logged every 15 seconds, which of course is part of the reason why it takes longer to load. But it is still much longer than the same line chart takes in Power BI.
I know that this can be done in Excel very easily. However, Power BI is very useful for me to compare different batch's trend data.
Clearly there is a demand for this type of chart. Creating a Power BI version would be very helpful. Thank you!
