I set up thing/device/variables/dashboard and data is transferred into IoT Cloud succesfully. In the dashboard I set up a chart to display one variable.
When I enter the web dashboard the chart's live section is initially empty. It is not filled unless two data points are tranferred from my device into the IoT cloud. The sending interval is 20s, so I have to wait for 20..40 seconds until I can see two data points. Every 20 seconds there is one more data point added.
When I enter the app dashboard (iOS, IoT Remote app), initially the chart is also ampty, with a message "No data available". After the first data point is transferred from the device into the IoT Cloud, it becomes visible as one data point in the chart. So I have to wait for 0..20 seconds until I can see the first data point. Every 20 seconds there is one more data point added.
As a customer I would expect to have the latest historical data points visible immediately when I open the dashboard. And the behavior of the web's and app's dashboard should be the same.
