(btw our tool also can create pivot tables/charts by CSV up to 500mb or databases)
Is it happening on each screen - pivot/charts/stats and what does the Chrome Dev console say? You could try to uncheck the "First line is a header" in the settings (cog image on the right) might help if you don't have a header and the first line contains strange symbols. Feel free to drop me a line at hello at streamingpivot dot com, happy to continue the discussion there.
Same issue here.
Any chance you can send me a small sample of the csv file?
Actually it was disk io stats pulled from a grafana graph fed by sysstats/telegraf. Unfortunately it is from a corporate env so that's a no no. But If you give me a couple of days I can do it from my own services.
The issue was the mime type not being set to text/csv when ingesting, could you maybe give it another run?
