Graphing Widget

The graphing widget shows graphs using the Rickshaw graphing library. The names of data fields should be (vaguely) familiar if you've used Rickshaw before.

It's recommended that you replace the /assets/javascripts/rickshaw.min.js from your dashboard with the latest from here.

Supported HTML data fields

  • data-title: Title to display.
  • data-displayed-value: If provided, then the value to display overtop of the graph. If not provided, then the most recent value will be used if there is only one series.
  • data-renderer: Any valid Rickshaw renderer, including 'area', 'line', 'bar', 'scatterplot'.
  • data-stroke: If "true", then area graphs will be drawn with a stroke.
  • data-unstack: If "true", then area and bar graphs will be "unstacked".
  • data-colors: A ":" separated list of colors to use for each plot. If there are fewer colors provided than there are series to graph, then pleasing colors will be automatically chosen. (e.g.: data-colors="#ccc:#ddd:#eee")
  • data-stroke-colors: A ":" separated list of colors to use for strokes.
  • data-color-scheme: One of "rainbow", "near-rainbow", "compliment", "default". Controls how default colors are assigned.
  • data-default-alpha: Alpha for default colors.
  • data-legend: If "true", then a legend will be added to your graph.
  • data-min and data-max: Set the highest and lowest values of the y-axis.
  • data-summary-method determines how the value shown in the graph is computed. If data-displayed-value is set, this is ignored. Otherwise this should be one of:
    • "last" - Default - If there is only one series, show the most recent value from that series.
    • "sum" - Sum of all values across all series.
    • "sumLast" - Sum of last values across all series.
    • "highest" - For stacked graphs, the highest single data point based on the sum of all series. For unstacked graphs, the highest single data point of any series.

Passing Data

Data can be provided in a number of formats. Data can be passed as a series of points:

points = [{x:1, y: 4}, {x:2, y:27}, {x:3, y:6}]
send_event('convergence', points: points)

Note that the x values are interpreted as unix timestamps. Data can also be passed as full-on Rickshaw-style series:

series = [
    {
        name: "Convergence",
        data: [{x:1, y: 4}, {x:2, y:27}, {x:3, y:6}]
    },
    {
        name: "Divergence",
        data: [{x:1, y: 5}, {x:2, y:2}, {x:3, y:9}]
    }
]
send_event('convergence', series: series)

You can even provide colors and strokes here, which will override the values defined in the HTML. Or data can be passed as Graphite-style data:

graphite = [
  {
    target: "stats_counts.http.ok",
    datapoints: [[10, 1378449600], [40, 1378452000], [53, 1378454400], [63, 1378456800], [27, 1378459200]]
  },
  {
    target: "stats_counts.http.err",
    datapoints: [[0, 1378449600], [4, 1378452000], [nil, 1378454400], [3, 1378456800], [0, 1378459200]]
  }
]
send_event('http', series: graphite)

You can even send data as JSON strings, straight from Graphite:

require "rest-client"
SCHEDULER.every '10s', :first_in => 0 do
    target = "aliasSub(summarize(stats_counts.http.*%2C%2720min%27)%2C%27%5E.*http.(%5Cw*).*%27%2C%27%5C1%27)"
    url = "http://graphteserver.local:8000/render?format=json&target=#{target}&from=today"
    graphite_json_data = RestClient.get url
    send_event 'http_counts', { series: graphite_json_data }

could you demonstrate a couple curl calls to utilize these graphs? I'm having a bit of trouble getting the graph to render the data I post, regardless of which format listed above I attempt to feed a widget.

wolfspyre commented Mar 2, 2015

Pretty please? Or point to an example git repo with sample jobs posting data in the proper formats to sample dashboards which display said data for the supported data types? It's mildly difficult for me to piece together all the bits, and examples speak volumes as to how the different parts play together.

I opened an issue against dashing here describing what I'm trying to do, and providing sample debug information. I believe I'm generating the graphite data correctly for send_event, but I'm unable to get graphs to actually render with data. Hopefully, someone will have a greater clue than I what I'm doing wrong, and also have the inclination to point me in the right direction.

Im having problems when the widgets span more than one row, it seems possibly the padding is'nt taken into account. I have made the edit as recommended above.

  _createGraph: ->
    $node = $(@node)
    $container = $node.parent()
    @clear()
    # Gross hacks. Let's fix this.
    width = (Dashing.widget_base_dimensions[0] * $container.data("sizex")) + Dashing.widget_margins[0] * 2 * ($container.data("sizex") - 1)
    height = (Dashing.widget_base_dimensions[1] * $container.data("sizey")) + Dashing.widget_margins[1] * 2 * ($container.data("sizey") - 1)
    ```
Any help would be appreciated! Thanks

Does anyone have troubles with the "unstack" attribute?
When I'm using it, it is still stacked when using areas, or not aligned as it should when using bars.

My x values are epoc values derived from the 1st day of the month.
For some reason it shows a future month off the widget, resulting in the month overlapping the next widget.
Anyone have an idea how to curb this?

If the series length is unequal, the line graph is not getting rendered properly. Did someone else have same issue?

Great widget, however I'm having trouble with a sizing issue and would welcome any help.

I want to shrink the widget content so that it isn't being drawn from 0,0 and add some padding into it. Currently the labels are all squished and it doesn't look great.

Thanks.

Has anyone got this working with renderer 'multi'?

I'm trying to build a burnup chart with this and it's so very close to exactly what I need.

my code looks like this but doesn't work:

in the erb file:

<li data-row="3" data-col="4" data-sizex="2" data-sizey="1">
    <div data-id="burnup-chart" data-view="Rickshawgraph" data-renderer="multi" data-max="40"></div>
</li>

and i want to pass the data like so:

iterationEstimates = []
iterationEstimates.push({name: "Delivered", renderer: "bar", data: currentPoints}, {name: "Estimated", renderer: "line", data: estimatePoints}, {name: "Outlook", renderer: "line", data: outlookPoints})

Where currentPoints, estimatePoints, and outlookPoints are predefined x and y points.

Has anyone managed to do something like this? If so.... how? :)

Hi,
im having this problem with "redcarpet" when im loading the widget.

i installed the GEM but still failing.

iWARN: tilt autoloading 'redcarpet' in a non thread-safe way; explicit require 'r
edcarpet' suggested.

@andrescolodrero, I'm running into the same issue as you. Any progress?

does anyone else have major problems with the axis?

the X axis tick text overwrites itself when using a time base, so you can't read it as it tries to write 24 hours worth of hh:mm text in one column of space!

the Y axis scaling seems a bit random - i've got values that are all over 20 and yet the line graph Y ticks are 0,5,10,20, so you end up with a vertically squashed graph at the top of the widget and the bottom 90% of the widget empty.

so is there any way to auto-scale the Y axis (not data-min/data-max as it needs to be dynamic) and/or limit the number of X ticks?

@sej7278 you can send min and max in you send event so for raw graphite data you can do:

def data_with_minmax(nested_array)
  out = nested_array.first[:datapoints].collect {|ind| ind[0]}.minmax
  {series: nested_array, min: out[0]-1, max: out[1]+1 }
end

send_event("open_tickets"  , data_with_minmax(graphite_data) )

Results

@andrescolodrero, @zd-cseeman, I ran into the redcarpet problem as well. The solution is to add gem 'redcarpet' to your Gemfile.

@snayler0 did you ever get the multi renderer working? I've tried it about 20 different ways and have yet to get it working.

@derro, @aireater, @jwalton
I believe the unstack option failing is due to this issue.

I think this is fixed in my fork.

@davepmarshall thanks that fixed it!

@MattRK, i got multi rendering working:

Simply send your event like so, setting your renderer for each plot:

        series = [
          {
            name: 'Lines Added',
            data: lines_added_points,
            renderer: 'bar'
          },
          {
            name: 'Lines Deleted',
            data: lines_deleted_points,
            renderer: 'bar'
          },
          {
            name: 'Linear Regression',
            data: line_fit_points,
            renderer: 'line'
          }
        ]
        send_event("code churn #{data_id}", series: series)

And in your graph2.coffee, change the graphOptions to set the renderer as multi:

    graphOptions = {
        element:  $graph.get(0),
        renderer: 'multi',
        width:    width,
        height:   height,
        series:   series,
        stack:    !@get('unstack')
      }

Let me know if that works for you... i did multi rendering 2 months ago so i maybe forgetting something else, but that's all i remember now :shipit:

@aysark, this is quite out of context, could you please elaborate on this? Tried everything you mentioned and it doesn't work :(

It seems to be impossible to change graph X-axis label color from default black to anything else, e.g. white?

Interestingly the Y-axis label color can be changed easily through the CSS.

Can anyone please help?

@cob16 - I can see that your graph has white labels, how did you make it work?

Sorry but I have to ask, how can I use this widget?

I have no experience with coffee nor scss.

I asked a question in SO (http://stackoverflow.com/questions/35272320/how-to-use-rickshawgraph-of-django-dashing) about this..

I have learnt to delete my history.yml file everytime prior to starting Dashing, this seems to help with bad "crashy" data not being used.

However, my problem is that I just can't get my X axis ticks to display, despite passing in unix timestamps, my data look like:
{"x"=>1461898499, "y"=>3.255}
I don't have any ticks or values displayed at all on the X axis

I'm having a hard time working out how I can apply the documentation on the official Rickshaw page to Rickshaw-Dashing. The official Rickshaw docs (http://code.shutterstock.com/rickshaw/) suggest to enable time, use this:

var xAxis = new Rickshaw.Graph.Axis.Time({
    graph: graph
});

xAxis.render();

...but I've got no idea where that goes or how it applies to rickshaw-dashing. Does anyone have any help?

Hi! Great widget!!

Has anyone implemented a graph with two y-axis? If so, can you share the solution?
I've seen it done in a Rickshaw example page, but so far I was not able to get it working on Dashing.

Hi, is there a way to change the x-axis to display beneath the graph area?

Hello
Is it possible to hide/remove the x-axis?
