D3-based histogramming and plotting library (for use in IceCube and other projects). This is a work in progress.
The following examples were all created from this HTML:
The HTML is pretty self-explanatory and serves as API documentation for the time being :-).
NOTE: you must use or adapt the styling rules in
style.css or your graphs will look hideously ugly.
Again, example.html shows one way to do it.
We looked around at quite a few JavaScript plotting libraries which might meet our requirements, which are (watch this space for updated status as the project progresses):
- High graphical signal/noise ratio
- Histograms / bar graphs based on provided array of bin heights
- Set color, transparency of histogram
- Scatter plots
- Line graphs
- Display X and Y axes, with labels
- Multiple graphs/histograms per plot
- Add rectangular highlights to X-ranges under plot
- Draw horizontal, vertical and other lines on top of plots
- Add text to plot in either data or display units
- Wrap everything in an object to avoid namespace pollution
- Time series X-axes
- Log / linear y-axes
- Two-sided error bars for points and histograms
- Allow addition of titles to plots
- Zooming / panning, with selective zoom on either access by holding shift key
- Minor (unlabled) gridline for X (or T) axes
- Axis-free representations (sparklines)
- Exporting plot graphic (either SVG or PDF would be OK)
- Show (x,y) plot coordinates of mouse [?]
- Optional grids in chart backgrounds
- Ability to “reset” the plot (if, for example, zoomed beyond recognition)
- Exporting data from plot
None of the canned plotting / graphing packages we looked at were quite what we wanted; D3.js does not provide these directly but is sufficiently powerful, flexible and fast to provide a foundation to allow us to implement these ourselves.
You can use Bower to pull down i3d3's dependencies. Just run bower install.
To update Bower with a new version, first update bower.json, then:
git tag <version>
git push --tags
