You can select shown interval, selected and all data from the options. But shown interval currently downloads whatever data has been fetched, which is limited to the current server's maxDataNodes and maxDataPoints. I suggest these changes:
Rename "Download selected" to "Download selected rows"
Rename "Download shown interval" to "Download selected range" and change the functionality so that it orders the same job as when downloading all data, but with the additional startIndex and endIndex parameters.
Rename the title "Download" to "Download log data for 11 mnemonics" or something similar to make it clear that data will only be downloaded for the selected mnemonics.
