I have a Stacked bar chart, and i need to change the colors of the bar; each measure is the name of the header in a column so Pick&Match doesn't work.I would also like to change the line color. Please help me
That looks like a Qlik Sense chart. If so then it can't be done. You can't specify colors for each separate measure in Qlik Sense. If you need that you'll have to code an extension that provides that functionality.
