A flashy Rickshawgraph with the ability to modify the background color of the top data series

I am facing a challenge in modifying the background color of the rickshawgraph widget in dashing based on the maximum value of the highest graph from the latest incoming data. While I have successfully implemented this feature for one series, I am struggling to extend it to handle multiple series within a single graph. The code snippet below is extracted from the rickshawgraph.coffee file. I understand that I need to implement a loop to iterate through each series, identify the one with the highest value, and then proceed with the remaining logic. However, I'm encountering difficulties with the syntax. Any assistance would be greatly appreciated. The complete files are provided below.

  node = $(@node)
  series = @_parseData {points: @get('points'), series: @get('series')}
  data = series[0].data
  values = data[data.length - 1].y
  cool = parseInt node.data "cool"
  warm = parseInt node.data "warm"
   ...

Answer №1

My recommendation is to make the following changes. Within the "assets/stylesheets/application.scss" file, there are predefined warning and danger colors that you can customize or add new ones.

When working with your rickshaw graph widget, include the following snippet:

onData: (data) ->
 if data.status
    # clear existing "status-*" classes
    $(@get('node')).attr 'class', (i,c) ->
      c.replace /\bstatus-\S+/g, ''
    # add new class
    $(@get('node')).addClass "status-#{data.status}"

In your job's .rb file, define a status and send it accordingly.

For instance:

if count < 50
   status = 'warning'
else
   status = 'danger'
end

send_event('thread-count', { value: count, status: status } )

In this scenario, if the count is less than 50, it will display yellow blinking text; otherwise, it will be red.

IMPORTANT: The animation feature may not function properly in Firefox but works seamlessly in Safari and Chrome.

This answer showcases a simple and elegant solution. I had to make some adjustments because my charts utilized data-colors and data-stroke colors. Providing it here for reference.

To integrate into rickhawgraph.coffee at the beginning of the onData section:

  onData: (data) ->
    if data.status
      # remove existing "status-*" classes
      $(@get('node')).attr 'class', (i,c) ->
        c.replace /\bstatus-\S+/g, ''
      @assignedColors = ""
      @strokeColors = ""
      # add new class
      $(@get('node')).addClass "status-#{data.status}"
    else
      @assignedColors = @get('colors').split(':') if @get('colors')
      @strokeColors = ""

The HTML part:

<li data-row="1" data-col="1" data-sizex="2" data-sizey="4">
    <div data-id="apdex_score_stage" data-view="Rickshawgraph" data-bind-data-min="0" data-max="1" data-title="Apdex Score (1-Excellent)" class="" data-colors="#4D4D94" data-stroke-colors="#707070" data-unstack="false" data-stroke="true" data-default-alpha="0.5" data-legend="false" data-summary-method="last"></div>
</li>

Within the script:

 apdex_status=""

        if apdex_score_values_array_min.min < 1 #yellow if one of the values is less than 1
    apdex_status="danger"
end

print apdex_score_values_array_min[1]

if apdex_score_values_array_min[1] < 1 #red if last value is less than 1
    apdex_status="warning"
end

#red if last value is less than 1
if apdex_score_values_array_min.min == 1.0 #nothing to worry, no status
  apdex_status=""
end


send_event("apdex_score_stage", min: apdex_score_values_array_min.round(2), status: apdex_status, points: apdex_score_array)

Data-binding plays a crucial role in this setup for the rickshaw graph.
