Now I want to overprint all of them in a new bar graph like the picture below(Figure 1).Briefly, it is called 2D histogram by the author (Kay, N. J. et al,JPCC,2011,115,43,21402-21408) .The descriptions about the figure are as follows: 1.The color scaling represents the density of points having a high conductance, ranging from low (darker blue) to high (red). 2.To construct this 2-D plot, we employed a bin size of 0.012 nS for the conductance data(Y) and a bin size of 0.015 nm for the distance data(X). I am trying to plot this kind of 2D histogram.Firstly,I active my worksheet and get a matrix(X and Y columns)---Descriptive Statistics---2D Frequency Count/Binning---set x,y bin---check 'Output matrix').Secondly,plot the matrix(('Plot: Wire/Bar/Symbol: Bars') and only get figure 2 . [img]http://www.originlab.com/ftp/forum_and_kbase/Images/safaf.jpg[/img] I have been trying for some time now but do not have a solution to plot the histogram like Figure 1. Questions: 1.How can I make this 3D bar in 2D pespective like Figure 1? 2.Can the colorful scale bar be continuous ? Many thanks£¡ [/quote]   Check here to include your profile signature.
