Move the legend

Can I move the legend from the right to the left or the top in a bar chart?

Yes. Did you try reading the Google Charts manual for bar charts?

Also, can I avoid displaying empty rows in the bar chart?

Yes. Again, did you try reading about this plugin?

It’s probably going to help you to know about the tools you use. I’m not going to give you every answer if you’ve shown no sign of doing even the basic research yourself first, especially as this is the third thread you’ve opened with such a question in as many days.

Can you please provide me with the link for documentation of this plugin.

The link is on this page (like, this one, the one you used to post this message from).

I thought there was a more detailed one somewhere.

Try the other tabs. The “Other Notes” tab has a complete list of every supported shortcode attribute.
