A bar chart cannot be combined with a line chart as of now. As a workaround, you can create a chart with a combination of column and line chart and rotate the chart-container(div) by 90deg as shown in this JSFiddle.
I checked it out , but Y axis is not shared by them , I want both of them to use same y axis.Do you guys have any idea to implement this feature ? I asked it before 4 years.
In the JSFiddle shared both bar(column) and line chart shares the same y-axis. If this doesn’t fulfill your requirements, kindly share an example and brief us more about your requirement so that we can understand your scenario better and help you out.
