I try search in chart.js documentation, and in stack overflow but don't find solution Unfortunately, the Chart JS documention on bubble charts is severely lacking as well.

     options: {
                    animation: false,
                    onClick: (e, i) => {
                        if (i.length) {
                            const bubbleSelected = i[0];
                            wordsTopic = `Topic${bubbleSelected.datasetIndex + 1}`
                            aBarCh.changeCanvas({data:groupDataByTopics(JSONDATA),topic:wordsTopic})
                        } else {
                            wordsTopic = `Default`
                            aBarCh.changeCanvas({data:groupDataByTopics(JSONDATA),topic:wordsTopic})
                        }
                    },
                    onHover: (e, i) => {
                        if (i.length) {
                            const bubbleSelected = i[0];
                            if(wordsTopic !== `Topic${bubbleSelected.datasetIndex + 1}`){
                                aBarCh.changeCanvas({data:groupDataByTopics(JSONDATA),topic:`Topic${bubbleSelected.datasetIndex + 1}`})
                            }
                        } else {
                            aBarCh.changeCanvas({data:groupDataByTopics(JSONDATA),topic:wordsTopic})

I had the same issue and adding this config to the chart's options solved the problem for me:

layout: {
  autoPadding: false,
},

Adding some inner padding to the axis overriding the min and max values could be also needed.
