bizcharts example : Doughnut Chart

Chart UI

key codes explaintion:

<Coord type='theta' innerRadius={0.45} />
without 'innerRadius={0.45}', UI will looks like:

without below codes, UI will looks like:

<Geom select={[false,{}]} type='intervalStack' position='percent' 

  color={['type', ['rgba(255, 255, 255, 0)']]} 

  style={{stroke: 'rgba(152,191,182,1)', lineWidth: 1}}> 

</Geom>

sed replace shell variable which include slash ('/')

Test content

cat test-sed.txt
aaa/bbb/ccc/ddd/eee
fff/ggg/ss

replace "ccc/ddd" to "CCC/DDD" via sed

NEW_STRING="CCC/DDD"
sed -i "s:ccc/ddd:${NEW_STRING}:" test-sed.txt

Notes:

1. use ':' as seperate char rather than '/', which is default
2. use "" include the replace command

Await is a reserved word error

Solution:

In order to use await, the function directly enclosing it needs to be async.
example codes:

async tryGetUserName() {   let session = await Auth.currentSession();   ...... } 

async should be there, otherwise you will get the error.
