I am having trouble working with the Ignition Chart. I have posted a video on youtube just to show you what issue I am having: youtube.com/watch?v=8GxlugF … e=youtu.be
As you can see I am trying to plot a trend graph with the chart object. There should only be two continuous lines, but there are multiple streaks as the graph updates itself. I can’t seem to fix this problem.
The data is from the Ignition Historian that is reading OPC tags and storing them to a database. The chart then reads the database data based off a SQL Query that is updated based on the stated conditions.
I think the problem is that I am updating the Chart’s SQL Query data set too quickly and it is plotting over and over again?
Let me know if there is a way to fix this issue with the charts. The current version of my ignition platform is 7.6.6 and it is running on windows 7 32 bit.
