The first example is contrived data that you can see here. Dataset types are assigned with the parameters "dataset0Type", "dataset1Type", and so on. Available types include Line, Stick, and HLOC. This chart expects dates in the first column and additional columns of data are consumed as follows: each "Stick" dataset uses a single column, each "Line" dataset uses a single column, and each HLOC dataset uses 3 columns - high, low, and close observations.
This chart is a conventional HiLoClose chart, which expects a column of dates, and 3 additional columns of high, low, and close observations.
This Stick chart is similar to a Bar chart, but more appropriate for certain kinds of financial observations: It expects a column of dates and additional columns of observations defining the stick height. Because the bars are a single pixel wide, many observations can fit on a single chart, and because this chart uses a DateAxis, it will automatically create labels appropriate for Date or Time information.
