The chm parameter is passed using the options similarly to other parameters.
The chd parameter is passed through the visualization DataTable. However,
there is no equivalent way to add the 't1' part description so you would
need the following table format:
In the example of the playground you have labels column followed by 4 number
columns. You need to add the bars column between the labels and the 4 number
columns of the candles.
Additionally, you need to add the option
options.firstHiddenColumn = 2;
To make the 4 last number columns not to appear as bars.
All other paramets should be passed via options as you did in the charts api
example (including the cht='bvg' and not 'lc').
Hope this helps,
