Agree. kde-edu mailing list would be the appropriate place for such discussions. P.S.: at the moment, 'labplot2 ' opens the import file dialog only. The same happens when doing drag&drop with a data file. -- You are receiving this mail because: You are watching all bug changes.

Various cases can be handled with suitable command-line options. For instance, Grace uses the "-nxy" switch to indicate that following file is organised in several data columns, the first one being the common abcissa and the rest the curves to plot. Anyway, a bug tracker is not the best place to discuss that. I'll try to subscribe to some labplot mailing list and eventually make there my humble contribution to the discussion. Orestes.

It will be very helpful if Labplot > had such a feature. In principle this is easy to implement in LabPlot, too. The problem is that the different users have different scenarios here. Some people want to get the data automatically imported into a spreadsheet or into a matrix with 'labplot2 for further editing first, some people want to get the import dialog shown so they can set the settings for the file parsing, some people deal with live data and want our "add live data source" dialog to be shown where they can set the read options, some other users want to directly get the plots generated like in xmgrace. We're thinking about this already, we need to come up with a user-friendly command line interface to cope with all these possible use-cases. For example, xmgrace on a file with a custom header having the string values for the column names has issues - the error message "Column count incorrect" is shown and nothing is plotted. Also, how to generate one plot with one curve for every y-column in the data and how to add all curves to the same plot? This kind of different scenarios has to be taken care of here. But I agree with you in general, a 'labplot2 ' with all the read, parse and plot parameters set internally to reasonable values so that the user can directly see the plotted data would be great. -- You are receiving this mail because: You are watching all bug changes.

I tried to obtain a live plot update from data coming from Gnucap circuit simulation software. Give me some days (I'm in the middle of exam assessements) and perhaps I can provide you an example. Anyway, Labplot2 is a really great application, and its development seemed stalled few years ago but with your recent work and the porting to Frameworks I foresee a bright future for it. One suggestion: I used (and still do) Grace to plot my data, mainly because obtaining a rough graph from command-line is super-easy: simply "xmgrace " and you got it. It will be very helpful if Labplot had such a feature. Regards, Orestes. -- You are receiving this mail because: You are watching all bug changes.

How do you change the file?
