The width of a bar chart doesn't correspond to the width of the aggregation interval

created 6 years ago

Hi

I am trying to create a chart with a daily line series and a monthly bar chart of aggregated values. I have made a small change to your demo and attached a screenshot of how it looks to give you an idea of what i am seeing. (see MonthlyBarChart.JPG). For this sample i am looking for the pink bars to be a month wide since they include data for a month. They look 1 day wide.

In the past if have used the asp .net chart control and it would expand the width of the bars to fill the entire month if that was the period you aggregated by.
(For reference see dxChartVsASPChart.jpg where top half is dxChart and bottom is ASP .net Chart

Is there a way to include this feature in dxCharts?

Regards,
Ricard

    Hi,
    I have investigated our API and did not find a way to expand bars in a case where a few series are used and one of them is aggregated. The key point is that even if the barWidth field is set the size of a series point is limited by the current aggregation interval. I am going to discuss this behavior with my team to check if we can provide a workaround in further versions.
