Proto REPL Charts is an Atom plugin that extends Proto REPL and allows you to display tables and graphs of results from executed Clojure Code.
Execute this in Proto REPL:
(proto-repl-charts.charts/line-chart
"Trigonometry"
{"sin" (map #(Math/sin %) (range 0.0 6.0 0.2))
"cos" (map #(Math/cos %) (range 0.0 6.0 0.2))})... and display this:
- Install Proto REPL.
apm install proto-repl-chartsor go to your Atom settings, select "+ Install" and search for "proto-repl-charts".
Proto REPL Charts are invoked from Clojure code run in Proto REPL. A very small Clojure library, proto-repl-charts, defines a namespace prc with functions for displaying different charts.
(Not necessary for self hosted REPL. The dependency is already available.)
Add
project.clj file.
(Proto REPL comes with a default Clojure project. If you bring open a new Atom window for and start a REPL it will already have proto-repl-charts dependency loaded and available.)
2. Start the REPL in Proto REPL and wait for it to come up.
3. Execute one of the functions in the proto-repl-charts.<chart-type-ns> namespace. See the examples below.
The chart functions are all of the form (proto-repl-charts.<chart-type-ns>/<function-name> <tab-name> <series-map> <[options]>)
chart-type-ns- one ofcanvas,charts,graph, ortablefunction-name- the name of the function to invoketab-name- is the name of the chart to put in the Atom tab. Repeated execution will replace the chart in the tab with the matching name.series-map- should be a map of series names to a sequence of values for that series. For example{"alpha" [1 2 3], "beta" [2 4 5]}would display two series named alpha and beta with the values 1, 2, and 3 for alpha and 2, 4, and 5 for beta.options- an optional map of display options. The only option supported right now is:labelswhich is a list of labels. The index of the label in the list corresponds to the index of the values in the series.
(let [input-values (range 0.0 6.0 0.5)]
(proto-repl-charts.charts/line-chart
"Trigonometry"
{"sin" (map #(Math/sin %) input-values)
"cos" (map #(Math/cos %) input-values)}
{:labels input-values}))
(proto-repl-charts.charts/bar-chart
"GDP_By_Year"
{"2013" [16768 9469 4919 3731]
"2014" [17418 10380 4616 3859]}
{:labels ["US" "China" "Japan" "Germany"]})
(let [tlr (java.util.concurrent.ThreadLocalRandom/current)]
(proto-repl-charts.charts/scatter-chart
"Randoms"
{:gaussian (repeatedly 200 #(.nextGaussian tlr))
:uniform (repeatedly 200 #(.nextDouble tlr))}))
Displays a custom chart in a tab with the given name. C3 is the charting library used. The chart config will be converted from Clojure to a JavaScript object and passed to C3. It can be any configuration data C3 supports. See C3 examples for more.
(proto-repl-charts.charts/custom-chart
"Custom"
{:data {:columns
[["data1" 30 20 50 40 60 50]
["data2" 200 130 90 240 130 220]
["data3" 300 200 160 400 250 250]
["data4" 200 130 90 240 130 220]
["data5" 130 120 150 140 160 150]
["data6" 90 70 20 50 60 120]]
:type "bar"
:types {:data3 "spline"
:data4 "line"
:data6 "area"}
:groups [["data1" "data2"]]}})
Proto REPL Charts can display a table of data that can be sorted by individual columns. The row data can either be a sequence of sequences or a sequence of maps.
(proto-repl-charts.table/table
"Users"
[{:name "Jane" :age 24 :favorite-color :blue}
{:name "Matt" :age 28 :favorite-color :red}
{:name "Austin" :age 56 :favorite-color :green}
{:name "Lisa" :age 32 :favorite-color :green}
{:name "Peter" :age 32 :favorite-color :green}])
Graphs of networks of nodes and edges can be displayed using the proto-repl-charts.graph/graph function.
See Graphs for details.
Proto REPL Charts supports building more complex visualizations by drawing on an HTML canvas embedded within Atom using the proto-repl-charts.canvas/draw function.
See Canvas for details.
