the bottom axis date time. left axis fixed , has words labels. need show gap in data.

yes, looks weird @ first glance , error message not pointing in right direction.

the reason try add points series before have added series chart.

rangebar cannot combined other chart type except bar-type charts.

therefore (?) chart can't check if points added in valid way , instead of saying claims series accepts 1 y-value.

solution: add series2 chart before adding datapoints , well..
