Following are some recommended edits to the Canvas UI text for consistency.

• click the Change Datasource link below -> click Change your data source above

• Elasticsearch Raw Documents -> Elasticsearch raw documents (sentence case)
• Use timelion syntax -> Use Timelion syntax
• Demo data -> Demo data
• Mock data set with with -> Mock data set with
• prices, projects, countries and phases. -> (no ending period for consistency)
• get a datatable -> get a data table (2 words)

• Welcome to the Markdown Element. -> Welcome to the Markdown element (lowercase e, no ending period)
• The datatable -> data table
• time cost username price age country state project -> time, cost, username, price, age, country, state, project. (use commas to make the sentence easier to read).
• Handebars Documentation -> Handlebars documentation. (lower case d, ending period)

• Overall, you should be consistent with case. The labels here use both title case and sentence case. The EUI guideline is sentence case, which means it should be Dimensions & metrics, Chart style, and Element style.
• Another place for consistency is whether to use the ending period. This screen uses an ending period for the text under X-Axis, but not under not Y-Axis.

• The drop down menus are also inconsistent with capitalization and use of ending punctuation.

• A static image. -> A static image (remove ending period because none of the other ones have one.

I'd be happy to go through the text together with you and identify the areas where we need to be consistent.
