Hello,
I am experiencing two issues in the Ignition Vision Easy Chart after enabling historian logging on one of my tags. I have attached screenshots/figures that show both issues clearly.
Issue 1 – Value does not update instantly on the chart
When I change the tag value from 0 to 10,000, the Easy Chart does not jump directly to the new value.
Instead, it slowly increases in small steps (for example: 0 → 20 → 24.5 → …) until it approaches the target value. However, in the database, the correct value is logged immediately (for example: 10000 is stored instantly when I change 0 → 10000).
Note : Refer figure 1 for issue 1

Issue 2 – Decimal drift when setting small values
When I change the value from 0 to 10,000, the chart should show exactly 10,000.
Instead, it shows drifting value like 9,119.232, 9,118.213, etc.
The value does not remain fixed at the number I set, even though the historian logs the exact value correctly.
Note : Refer figure 2 for issue 2

Figure 3: Refer to my tag configuration and the historian-enabled configuration
