Hello there! I ran into a same trouble a couple of days ago and found a
solution how to use a bar chart and line chart so that the filtering does not
cut off the data. This solved my problem with dataZoom
All that is needed is to change the weakFilter behavior logic in the
sources. For a line chart, using filters causes problems when 1-2 points
remain, but @cfwang123 was able to find a solution to the problem of filter
behavior, I suggest using the old filter for the bar chart, and in all other
situations, the modified filter @cfwang123
from:
`var thisLeftOut = value < valueWindow[0];`
`var thisRightOut = value > valueWindow[1]; `
to:
`if(seriesModel.subType === 'bar') {`
` var thisLeftOut = value < valueWindow[0];`
` var thisRightOut = value > valueWindow[1];`
`} else {`
` var thisLeftOut = value < valueWindow[0] && seriesData.get(dataDims[i],
dataIndex+1) < valueWindow[0];`
` var thisRightOut = value > valueWindow[1] &&
seriesData.get(dataDims[i], dataIndex-1) > valueWindow[1];`
`}`
