2 sets of data on single chart with different line style


I have 2 or more sets/groups of data
I am using line chart.

each entity with a group is color coded. so cant use color to differentiate between group entities.
So left option is to use different line styles like dotted, dashed, dotted and dashed, thick / thin etc.

How can I set line styles in line carts?


line charts can not be dotted. However, you may set line width and control item radiuses:



here is the sample dhtmlxChart/samples/05_line_chart/02_style.html
