Re: [Gretl-users] new things in CVS

Thanks very much for these. I am most grateful for the new features as I am currently using plots generated using gretl along with the LaTeX Beamer class to create very, very fancy looking econometrics lecture notes in Turkish. I have distributon graphs, multiple regression lines for comparing models, and all sorts of gretl plots and output in these notes. Soon I will put these on my web page under the creative cummons CC-by-SA license for everybody to benefit. I have tested the updates and everything seems to work pretty well. I have updated the tr.po file also. Here are a few suggestions for improvement: 1)- Ability to set more colors is great. What would be better is a small color button for each line, presumably next to the "line width" item. 2)- Also would be neat is a "remove" button, next to the "line width" as well. 3)- Some method to add vertical lines would be nice for completeness. 4)- Ability to use the existing scalars as input for the formulas would be nice for improved integration (but not crucial). 5)- The ability to define a horizontal range for every line would make gretl's gnoplot facility very very powerful, (but dashed lines comes first) 6)- Using the Gujarati Table_1.3.gdt, I again plot Canada versus France to see that I can now add horizontal lines such as y=1.3, but I cannot add any legends on this particular plot. (well, I can edit the legends fields but the contents don't show up) 7)- Adding line functionality doesn't work with the distribution graphs. 8)- Trying to remove or modify the legend in distribution graphs creates an error message. The error exists even if the legend is restored to its previous value, and closing the plot control window and reopening it also doesn't get rid of the error, rendering the plot completely uneditable. 9)- The newly added filter, which converts ',' to '.' in formulas when the locale decimal character is ',' seems to work OK but now I can have two formulas such as y=1.3 and y=2,3 together in the same window. This is inconsistent. How about making the process so that, when the wrong decimal point is used, the program does not proceed and warn the user about it. As an example, suppose the locale decimal point is ',' and the user enters, say, "1.3". Here, gretl would stop and give an error message about the '.' used. Once the user corrects the entry so that it is now 1,3 , gretl will first convert the ',' to '.' and go ahead and call gnuplot. 10)- Could the filter also filter "^"s and convert them to "**" please? This would be nice for the consistency of everything. Finally, I also agree with andreas that refing the gnuplot interface is the way to go. Graphing abilities is an important parameter defining the overall strength of a scientific program such as gretl. Gnuplot is already extremely powerful, so work improving gretl's interaction with it should have a high marginal return.
