I’d like to draw charts and indicators and put markers and notes on these.  Also, charting two or more syms and marking interesting points.

Which contributed visualization tools should I look at?

I generally use the R interface and do all of my plotting in there.It’s an extra step to transfer the data, but I haven’t found anythingthat comes close to ggplot2, IMO.JoshOn 13 October 2015 09:35 UTC, Jack Andrews wrote:> I’d like to draw charts and indicators and put markers and notes on these.> Also, charting two or more syms and marking interesting points.>> Which contributed visualization tools should I look at?>> Ta, Jack

If you want to avoid the extra step you can use rinit from here: https://git=
hub.com/kimtang/rinit

p) ggplot(`trade,aes(time,prx))+geom_point()

Here is trade a table living in Kdb.

q bindings for plplot: https://github.com/jaeheum/qplplot

qplplot supports 

  • plotting large data (e.g. 500ms to plot 100M data points)

  • both in interactive and in batch modes

  • many graphics formats

  • APIs, not commands

Or Python with Seaborn for example. Load the data into Python through pyq. http://code.kx.com/wiki/Contrib/PyQ http://stanford.edu/~mwaskom/software/seaborn-dev/examples/index.html

Data sets like share prices are commonly shown like  apple prices for the month [0]

does anyone have experience plotting sparse or “depleted” time series (or any series) where the domain is ordered, but non-continuous? 

the trick is choosing the right labels, whether it be just a year (“2013”) or mmm-yyyy (“Jan 2013”) using the space available in the length of the x-axis.

i’ve been drawing my charts in the browser with Javascript + SVG (and d3).  But would like it if there was something out there - a thin client for data sent from kdb+. I’ve looked at techan.js, but it’s design is rather thick client with the only data input being a price time series - I’d like to stack and grid financial charts with analytics from kdb+.

if not, i’ll continue on with “depletion” in the browser.
