Hello,

There is a kind of graph that is great for large analysis of time series data: horizon charts.
It exists this js library Cubism.js which implement this type of graph.

Mat,

There are currently (as of 0.7) no high level functions for constructing horizon charts, although it has been suggested for possible inclusion in the bokeh.charts interface. I do think a horizon chart would make a great addition to bokeh.charts, but for it to happen in the short term, would probably require a pull request from an interested new contributor. (If you have any interest in working up a bokeh.charts.Horizon PR please let us know!) That said, Bokeh can certainly draw everything needed for a horizon chart, but right now you’d have to compute all the horizons and specify the low level lines, patches, etc, to draw yourself.

Thanks,

Hi Mathieu,

There’s two ways:

• draw overlapping patches that have alpha < 1 so that the alpha values stack up and the shade of each patch is different.

• draw non-overlapping patches that have their color set explicitly

The latter offers more control but the former may be easier. You can see an example of “stacking areas” by hand here:

    [http://bokeh.pydata.org/en/latest/docs/gallery/brewer.html](http://bokeh.pydata.org/en/latest/docs/gallery/brewer.html)

There is also a bokeh.charts.Area high level schematic interface but it may not (curretntly) offer enough control for you.

Thanks, I lookk forward to seeing the result!

Hello Bryan,
still made some progress... I decided to play with overlapping area and alpha colors finally.

There is one last thing I cannot find how to fix: the y axis.
I need a linear axis even if I smash folds together and number not really match the ticks on the axis. Instead, what I would like to do is display is something similar to a categorical axis that represent the name of each serie of the time series. Is is possible to add another y axis on the plot?

Mat,

That looks great! You can add an additional y-axis, you can see an example here:

    [https://github.com/bokeh/bokeh/blob/master/examples/plotting/file/twin_axis.py](https://github.com/bokeh/bokeh/blob/master/examples/plotting/file/twin_axis.py)

Basically you configure the plot with an extra (named) range, then then you can add a new axis that refers to that range.

Bryan, two problems...

1) I am trying to put on the y axis strings, so I am doing this:

    plot.extra_y_ranges = {"series": FactorRange(factors=self.series)}

but I do get this error:

    "expected an element of Dict(String, Instance(Range1d)), got {'series': <bokeh.models.ranges.FactorRange object at 0x109e12c90>}"

How it is possible to add another type of axis?

2) How can I hide the original y axis in order to display only the second one?

thanks,
Mat

Mat,

That looks great! You can add an additional y-axis, you can see an example here:

        https://github.com/bokeh/bokeh/blob/master/examples/plotting/file/twin_axis.py

Basically you configure the plot with an extra (named) range, then then you can add a new axis that refers to that range.

I do think a horizon chart would make a great addition to bokeh.charts, but for it to happen in the short term, would probably require a pull request from an interested new contributor. (If you have any interest in working up a bokeh.charts.Horizon PR please let us know!) That said, Bokeh can certainly draw everything needed for a horizon chart, but right now you'd have to compute all the horizons and specify the low level lines, patches, etc, to draw yourself.

Hi Mathieu,

There’s two ways:

• draw overlapping patches that have alpha < 1 so that the alpha values stack up and the shade of each patch is different.

• draw non-overlapping patches that have their color set explicitly

The latter offers more control but the former may be easier. You can see an example of “stacking areas” by hand here:

    [http://bokeh.pydata.org/en/latest/docs/gallery/brewer.html](http://bokeh.pydata.org/en/latest/docs/gallery/brewer.html)

There is also a bokeh.charts.Area high level schematic interface but it may not (curretntly) offer enough control for you.

I do think a horizon chart would make a great addition to bokeh.charts, but for it to happen in the short term, would probably require a pull request from an interested new contributor. (If you have any interest in working up a bokeh.charts.Horizon PR please let us know!) That said, Bokeh can certainly draw everything needed for a horizon chart, but right now you'd have to compute all the horizons and specify the low level lines, patches, etc, to draw yourself.
