I fail at the first step, i.e. selecting the colormap. When I select a increment list ('Candy', 'Fire', 'Classic') the colors of the plot (plot.colormap) do change, but if I select any color palette ('Rainbow.pal', 'Maple.pal') the color of the plot doesn't change. According to the documentation of originpro.graph.Plot.colormap this should be working. Code used: [code] import originpro as op # Start a new origin project op.new() # Choose whether Origin should be visible or not (default = True) op.set_show(True) # Create grouped data set x = np.linspace(0, 10, 501) y1 = np.sin(x) y2 = np.sin(x+0.1) y3 = np.sin(x+0.2) y4 = np.sin(x+0.3) y5 = np.sin(x+0.4) # Create a new worksheet in writing mode wks = op.new_sheet('w') # Add data to the worksheet wks.from_list(0, x) wks.from_list(1, y1) wks.from_list(2, y2) wks.from_list(3, y3) wks.from_list(4, y4) wks.from_list(5, y5) # Create a figure gp = op.new_graph() # Create a graph object gl = gp[0] # Select the first layer # Plot entire worksheet plot = gl.add_plot(f'{wks.lt_range()}!(?,1:end)') # Group the plots gl.group() plot.colormap = 'Rainbow.pal' gl.rescale() [/code]   Check here to subscribe to this topic.
