Yes, you can combine error-bar chart with any other chart-types with axis. Please take a look at this gallery example for combination of line and error-bar charts.

@yong-min-lee,
You can use JavaScript Timing Events and update chart-data every few seconds. Please refer this example on live updating data from AJAX/JSON.
If this doesn’t solve your requirements, can you kindly share working sample project along with sample database over google-drive or onedrive so that we can understand it better and help you out?
