NVD3 visualisations give you tools on WordPress & Drupal 7 to generate impressive business quality charts based on the famous open NVD3 framework
Shortcode [jsChart] is your easy solution then: first create charts gallery by [demosGallery] shortcode & then start cloning your own charts to the new page/post. Each cloning of new chart creates you full example call of [jsChart] shortcode with a lot of options for it that you can try to turn on and off. All this happens safely in preview mode of WordPress before you are happy & ready to publish it all.
Sure, go to the charts gallery and select data input method Direct Input, press new chart button, and follow its further online help.
Also, you might like to take a look at shortcode_direct_data.txt on examples folder with this case, please.
You have 2 choices here: outside of chart container (normally div/span element & container) or inside its svg element. Take a look at example shortcode_margins_demo.txt to learn more about these options, please.
You can set palette of custom colors for each chart (bars, etc) separately with the following ways:
Look at your blog's root and the folder called charts_nvd3. Data sets are stored there by random names and they stay there until you remove them by FTP client manually. If you create very many/big data sets it is a pretty good idea to clean this folder from time to time.
Good point & question here !
YES indeed, the software is design so that it transparently creates and draws many charts on the same page and gives you exact control where you like to show them.
Note: since ver.1.8.0 charts gallery is improved to new visual form. If you need/prefer the old (table) type of look, you just call it by [demosGallery_old] shortcode.
Also, peek into examples folder of plugin and start to test shortcodes demos there with your blog.
No, you just remove all the options that you do not like/need and shortcode sets them to sensible default values automatically on the background.
Look at inside chart_options.html file and its comparisions table, please.
