Report:Timeseries Chart

Please Help Me!!!
In the report module, I want to achieve an effect as shown in Figure 1st, but i have got the last one.When I use TimeSeries Chart , I choose pen Style as bar(But I didn’t find anywhere where the width of the bar was successfully set)



It looks to me like you just have too much data for the width of the visible chart.
The bar width is dynamic compared to the chart width and number of points.

As shown , there are only 25 *3 data ,confusingly,the width of the bar has not changed.

Try changing the bar style to 3D bars.

In the 'Timeseries Chart ', i couldn’t found somewhere to set bar style to 3D bar, just like this

too few items can be set !
