Re: [Scilab-users] arrhenius plot with two x-axis
Hello, Le 15/05/2015 11:59, Krzysztof Lewandowski a écrit : I'm trying to make arrhenius plot of my data ('ln(S)' vs. '1000/T') with another x axis with 'T' on the top of the graph, but I have no idea how to do that. Is it possible to make such plot in scilab? If the additional axis is linear, you may use drawaxis(): http://help.scilab.org/docs/5.5.2/en_US/drawaxis.html Otherwise, newaxes() could be necessary: http://help.scilab.org/docs/5.5.2/en_US/newaxes.html Even with newaxes, it could be very difficult to match both bottom and top scales. To turn this feasible and easy was somewhat the purpose of this report: http://bugzilla.scilab.org/show_bug.cgi?id=7739 Its (too) implicit aim was to enable plots such that the bottom axis is in wavelengths L and the top axis is in corresponding wavenumbers n=1/L or frequencies f=c/L This kind of plot is very common in physics, but hard and tricky to get with scilab, at least when keeping the autotick mode. After the report 7739, i think that the best way to enable such plots could be to add a callback attribute to the drawaxis object, that would point to a function F(x) computing its x'(x) values, with x spanning x data_bounds, and x'(x) tick being drawn at the x position in data scale. Depending on F(x), a smart x' grid could be quite difficult to draw, in particular for minor ticks (if any).

[Scilab-users] arrhenius plot with two x-axis
Hello, I'm trying to make arrhenius plot of my data ('ln(S)' vs. '1000/T') with another x axis with 'T' on the top of the graph, but I have no idea how to do that. Is it possible to make such plot in scilab? Thanks, Chris ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
