minimax	Posted - 12/11/2024 : 09:35:56 AM Hi cts18488, Besides the lt_exec() method ChaoC mentioned, you may also try following import originpro as op ms=op.find_sheet('m', '[MBook1]') gl = op.new_graph(template='image')[0] gl.add_mplot(ms, z=0, type=220) #220 is image plot type id #https://www.originlab.com/doc/zh/LabTalk/ref/Plot-Type-IDs gl.rescale() pl = gl.plot_list()[0] zl = pl.zlevels zl['minors'] = 4 zl['levels'] = [0, 8, 16, 24, 32] pl.zlevels = zl pl.colormap = 'Beach.pal'
ChaoC	Posted - 12/10/2024 : 8:03:14 PM Hello, 1. You can activate your matrix and run: op.lt_exec('run.section(Plot3D.ogs,ImagePlot)') 2. Documentation for setting colormap: https://docs.originlab.com/originpro/classoriginpro_1_1graph_1_1Plot.html#a5d33966d43e1be87689f6488d418a542 3. You can use lt_exec with these LabTalk options: https://www.originlab.com/doc/LabTalk/ref/Layer-CMap-obj E.g op.lt_exec('layer.cmap.nummajorLevels=8') op.lt_exec('layer.cmap.setLevels(1)') Best, Chao
