Query regarding Column Chart

Hi

I am working on version 19.1.

I have a query regarding column chart. I have created a column chart. The code for this is:

load(
  local!pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: -1,
    sort: a!sortInfo(
      field: "month",
      ascending: true
    )
  ),
  local!monthSelected,
  local!monthDetails:index(
    a!queryEntity(
      entity: cons!MONTH_DETAILS,
      query: a!query(
        aggregation: a!queryAggregation(aggregationColumns: {
          a!queryAggregationColumn(field: "month", isGrouping: true),
          a!queryAggregationColumn(field: "id", alias: "count", aggregationFunction: "COUNT"),
        }),
        pagingInfo: local!pagingInfo
      )
    ),
    "data",
    {}
   ),
  a!columnChartField(
    categories: index(local!monthDetails, "month", null),
    series: {
      a!chartSeries(
        label: "Months",
        color:"AMBER",
        data: index(local!monthDetails, "id", null),
        links:a!forEach(
          items: local!monthDetails,
          expression: a!dynamicLink(
            value:index(fv!item, "month", null),
            saveInto:{
              local!monthSelected
            }
          )
        )
     )
    },
    xAxisTitle:"Months",
    yAxisTitle:"Population",
    showLegend: false,
    showTooltips: true,
    showDataLabels:true
  )
)

The chart created is:

If you go through the chart created, except 3 months the column for each created for each month is in the range of thousands. For the months Jan, Jun and Sep; the column is not displayed on the chart (I guess because of the range on Y Axis is 10,000 and Appian doesn't display the column for these months) My requirement is, the columns are clickable links. So for these three months i.e. Jan, Jun and Sep; I would like to know how can user click the columns as columns actually don't exist for these three months despite data values being there.

Thanks in advance!!
