We just upgraded from 8.0.12 to 8.1.0-rc2. Our Perspective project with Sparklines worked great prior to the upgrade. The sparkline displays machine speeds from tag history for current to 12 hours prior. Now, I get a red shade with green line and no data points on the Sparkline. The data table is 2 columns and 100 entries. Any idea why it doesn’t draw the sparkline anymore?
Anyone else seeing the same problem?
