Y-axis, type:'log' , series type :'bar', the first data value is 0, the bars on charts is not normal.
option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'log'
},
series: [{
data: [0, 200, 150, 80, 70, 110, 130],
type: 'bar'
}]
};
log(0) is -Infinity. So after removing 0 it will be OK.
But it is needed to be think whether to trade 0 as an empty data.
Yes,removing 0 it will be OK.
Based the series type is 'bar', normally, data 0 should be accepted. and the bar length should be zero.
As you said, if Echarts trade 0 as an empty data when Y-axis type is 'log' should be a good practices.
Hi @100pah Is there any update on this issue? It is essential in most enterprise applications to allow users to switch between log scale and linear scale, and zero/negative values should be treated as empty in those cases.
@100p @pavish It might not be ideal, but I've switch the data to null when the value is zero/negative and switch it back to its original value when using the linear scale.

@jonavila I guess I can use that for now, until the issue is fixed. Thanks!
@jonavila I have found a better workaround for the moment. While changing linear axis to log axis just change min value config option to 1.
eg.,
yAxis: { type: 'log', min: 1 }
Although, if your values are lesser than 1, just set the min value to the least value in your data.
Years later and still not fixed? If you have one zero data point in your series you can't really use log axis currently....
@100pah is possible to replace all 0 to null by dataset transform ?
trade 0 as an empty data should be as simple as possible
hello guyz, any update on this ? my data are dynamic and i cant replace the 0 with null or empty data because it's a big difference in my case , (0 means no traffic and null means i fetched no data at this time), please if someone has a fix let me know

workaround - replace 0 with '' (empty string) and keep the nulls too.
This issue seems to be related to data preparation, not a ECharts bug. Label priority-high is a kind of a overkill.

I disagree. 0 is a valid integer which should not cause a charting library to break.

the same here, 0 and null should be treated separately :(
