Hi,

It is possible to change the color of lines in a linechart:
1) Select the linechart
2) Open the component layout settings
3) Under the styles tab click the ‘customize’ toggle
4) Click color -> color palette
Here you can change the colors of the lines in the linechart.

Small note: Right now the color is not linked to the parameter but rather the order in which the data is fed to the component. We have a task on our backlog to adress this.
