Can anyone help me create graph of time ranges of all elements in Excel. My data looks like this:

I want to make:

Answer 1

Do the bars have to be different colors?

If not, you can use a clustered bar chart.

"Connected at" is one time series, "disconnected at" is another. The "connected at" series should be listed second in the data source window.

Format "connected at" with white border lines and white fill in the format data series pane.

Last step is to set the Series overlap to 100% in the Series Options pane.
