Chart not working

I have used Cayenne for some time without problem. However I added a new project and I am getting data displayed. Unfortunately when I try to display the data on a chart I get a blank chart. On trying to get a chart on other projects which used to display data on a chart I get a blank chart. What’s going wrong? Any help will be appreciated

Are you using the correct data types for your widgets? Are you using same channel number for two widgets?

Thanks for your reply. Yes I am pretty sure I am using the correct data types and separate channel number. I switched off the eps device so that I would not get any data and found my other devices which used to display charts now do not. What has gone wrong?

can you private message me your email id so i can into the issue.
