How to make infotable for proportional chart
Hello, Everyone.
I wnat to use a Proportional chart like as picture.

I have completed the tutorial. A proportional chart was created. (https://developer.thingworx.com/en/resources/guides/display-data-charts/ddc-configure-charts)

But, If I unchecked "Single data source" It doesn't work.
I would like to show the operating time of the equipment at a specific time in a proportional chart.
How can i do ?
Please provide it. If you have a sample program.
Best regard,
