couturier	Posted - 02/18/2015 : 03:57:22 AM Origin Ver. and Service Release (Select Help-->About Origin): 2015 SR1 Operating System:win7 64bit Hi, I have 20 cols. Each col has an associated parameter (which can be in a col header or in a separated 20 rows col). I'd like to plot those cols and set lines color according to this associated parameter. Right now, I plot the parameters in a temporary scatter graph, set symbol color as self colormap, get each point color and finally set the colors to the line plots. Is it possible to speed things up and directly generate a color list, based on the parameters and a given colormap ? Thanks

Castiel	Posted - 04/01/2015 : 09:15:07 AM Apply palette to your graph. There's an x-function for you to create a palette. (It's less straightforward though, comparing to the one in MATLAB.) After setting symbol/line color as colormap of some column data, you can change a layer's palette through toolbar. I don't recall if it's possible to apply a palette to a single plot (layer cmap? doubted). Maybe you can getformat() of a dataplot in origin-c for details. (travelling without pc, can't help...) �c�� ȥ� �f�u�c �c�� Τ� �c/ �� c�ʥ� �� ' �̩�� /�� թ��f �� ` ��
SeanMao	Posted - 03/31/2015 : 05:56:40 AM Hi, Currently there seems no better way to colormap a set of grouped data plots using dataset in another column. Regards! Sean OriginLab Tech. Service
couturier	Posted - 03/26/2015 : 10:20:40 AM Thanks Sean for your answer. The point is not setting color curves once the colors are known, but precisely how to compute the colors. Another way to expose the problem: I have a col I want to use for color mapping. Is there a way to generate a dataset that will store the color values, without having previously generated such a plot ?
SeanMao	Posted - 03/23/2015 : 06:19:09 AM Hi, Suppose you have color index in column Comments, you can run the following code to color data plots in active layer to use the increment list in column comments: // Suppose worksheet name is Book1, sheet name is Sheet1 layer -c; // Count how many data plots in active layer //and put value in Count variable for (nn = 1; nn <= count; nn++) { layer.plot = nn; // Active nnth data plot set %c -c %([Book1]Sheet1!wcol($(nn))[C]$); } Try and see whether this is what you want.

charlieelectra	Posted - 03/17/2015 : 06:06:08 AM Thanks for the reply. I was looking to post the same question.
couturier	Posted - 02/18/2015 : 08:11:13 AM Not sure the explanations were clear. Another way to formulate the question would be: I have 20 grouped plots. If I set line color increment to follow a palette, the color follows the plot index. Is it possible to have the palette follow another dataset (whose size=number of plot) or custom row header ?
