echarts.jl's Introduction

ECharts.jl

Julia Library that wraps fully the ECharts (Baidu) JS Library

The library is very thin and fast, and fully passes all args to ECharts API

See ECharts Demos in: https://ecomfe.github.io/echarts-examples/public/index.html

See ECharts API in: https://ecomfe.github.io/echarts-doc/public/en/option.html

Examples

using ECharts,DataFrames

#### Create Random DataFrame
points=50
df=DataFrame()
df[:x]=rand(points)*100
df[:y]=rand(points)*10
df[:series]=rand(["SerieA","SerieB"],points)
df[:symbolSize]=rand(10:1:25,points)
head(df)

	x	y	series	symbolSize
1	31.84270924596433	1.1291218016205407	SerieB	25
2	9.51935323310824	0.7565851121855416	SerieB	19
3	74.79062647870633	6.802525807551829	SerieA	20
4	28.670134613169918	1.063095167149788	SerieB	22
5	75.85640060366802	0.7252974837492654	SerieB	17
6	88.8391920100435	1.1211873678638784	SerieA	17

## simple Chart using series helper sintax
EChart(ctype="scatter",x=df[:x],y=df[:y],series=df[:series],symbolSize=df[:symbolSize])

## simple Chart using series helper sintax
EChart(ctype="pie",x=[1000,2000,3300],names=["A","B","C"])

## Fully customized Chart using API sintax
ECharts.EChart(Dict(
        "legend"=>Dict("data"=>["S1","S2","S3"]),
        "xAxis"=>Dict("type"=>"category","data"=>["X1","X2","X3","X4","X5"]),
        "yAxis"=>[Dict("type"=>"value","name"=>"Amount"),Dict("type"=>"value","name"=>"Number")],
        "series"=>[
            Dict("type"=>"bar","name"=>"S1","stack"=>"s","data"=>[100,200,350,920,700]),
            Dict("type"=>"bar","name"=>"S2","stack"=>"s","data"=>[60,120,50,30,40]),
            Dict("type"=>"line","name"=>"S3","yAxisIndex"=>1,"data"=>[10,90,80,40,100])

echarts.jl's Issues

Save EChart to disk (PNG or SVG export)

Dear Antonio,

ist is possible to export an EChart as PNG over even better as a vector graphic (SVG)? I am creating Sankey-Diagrams like in your example (https://randyzwitch.com/ECharts.jl/sankey) and would like to save the resulting image automatically.

In the EChart documentation I found this: https://ecomfe.github.io/echarts-doc/public/en/api.html#echartsInstance.getDataURL

but I don't know how to acess the getDataURL function via the Julia wrapper.

Any help or feature addition would be highly appreciated.

All the best, and keep up the good work
Andreas
