Hi Ying,

You can't download data by graph, but if the user has allowed data download for the workbook the you can get the entire datasource downlaod in excel format. You will get the download option.

It depends on publisher of the viz. While publishing the viz If the publisher has given that access to download the data then only you will get that option. Most of the time public users don't give the access to download their data.

When you save your viz in tableau public you'll get a notification at top saying save complete. There is a edit details option. Go to edit details options where in toolbar settings you'll get an option to enable the download option for others.

See the screen shots. Let me know If you've any query.

Edit details> Allow workbook and its data to be downloaded by others.

there is a other settings If you've more that one dashboards in your workbook you can select that too.

If you've already saved your viz in your public profile then view your viz at the top right corner there is a edit details option. You can change the setting from there also.

Hope this help.
