Suthiro, The 'Linear regression fit' is the same as 'Fit Linear', which is under the menu Analysis -> Quick Fit -> Fit Linear. This menu entry is visible when your graph window is in the 'first plane' (I don't know another way to describe it). If the window in the 'first plan' is a table, you'll not be able to access all fit options, but just the Fit Wizard.

Hi Suthiro, Are your data defined as 'numeric' or as 'text' in the table you used to create the plot? You can check this in the 'Type' tab on the right side of the table (see attached figure). Regards, Fellype

For what I can see on the bug report, it should be fixed on 2.5, am I correct? Well.. the exact number of the version I dont know. But will be in the next release (the current one is 2.3.0).
-
Hi Miguel, This is a known bug: https://sourceforge.net/p/scidavis/scidavis-bugs/400/ and has already been fixed, but a version with the fix hasn't been released. For now, it is possible to export all the existing tables in your project. Just activate the "all" checkbox.

Crashes when opening a SciDAVis project created from an Origin one
-
Regarding issue b) If you send me a sample project, maybe I can tell you what is wrong.
-
@Koushik and @LM, could you attach an opj file (with table(s) and graph(s)) here or send it to me at fellypao©yahoo.com.br (don't forget to replace © by @)? @LM, maybe the version of liborigin (3.0.0 - from 2018) shipped with SciDAVis does not support the file format generated by Origin 2019. So, the best that can be done is send a sample project to the liborigin team and wait for possible support in future versions of both SciDAVis and liborigin. @Koushik, I would like to check if to save an opj...
-
@Koushik and @LM, What version of Origin are you using? Origin files from version 8.x are working fine here (Linux, SciDAVis 2.3.0) - no crashes at all!
-
Hi Bedar, Just increase the gap between bars. I guess 82-85% will be good for your data. Do it for all datasets in the graph. Regards
-
Hi Miquel! The patch fix the orientation of bars in the graph. However, I found another bug: all tick marks for the dependent variable are the same, rounded to the highest one. Please, take a look at the attached project. I can open another ticket for this if you think it is appropriated. Regards

SciDavis isn't mature in my opinion and Origin and QtiPlot all have bugs but a competent development team addresses those bugs. Have you tried to report properly the bugs you have found at [1]? Have you took a look at [1] in order to check the number of bugs reported and how many were fixed? I agree that SciDAVis isn't as mature as other commercial/paid plotting tools. But the development team is good and very competent. The problem is that it is a small team. No one is making profit from SciDAVis....

When I face a limitation in SciDAVis graphs, I use Python + Matplotlib to do the job. It works from python notes in SciDAVis :-D Of course, the content of tables must be converted to arrays before it.

Hi Alexander, At the moment, the only way to align the axes is by adjusting the numeric format so to have the same number of characters in the axes labes. But, it is not always possible.
-
Hi Spyradion, Great job. Thanks for sharing it. Particularly, I don't use Windows. But I know that this will be very helpful to both users and developers. Python scripting is a missing feature in the Windows packages since SciDAVis 1.D8. Best regards, Fellype
-
This feature already exists, but it is not an automated task. The errors associated with a curve are treated as another curve in SciDAVis (1). Then, in the same way you attached a curve from left to right axis, you must attach the associated errors "curve" to the right axis too. (1) I'm not sure if this is a feature or a bug. Anyway, feature request #107 could be changed to: when changing the axis of a curve, automatically attach the associated errors to the corresponding axis.
-
Hi Miquel, Thank you for the patch. It works fine here. Best regards.
-
Is this bug present in SciDaVis 2.x? Yes. Same environment as in ticket #393 We're not intending to support 1.x and Python 3. I didn't understand what you mean. Will you drop python support on SciDAVis 2.x or will you move back to the EOLed Python 2 version?

Missing plot name in results log after fitting a curve
-
Hi Arthur, I don't know about the drag and drop behavior on MacOS. But to drag a file from a file manager and drop it on SciDAVis should work fine to import data files - .dat o anything else. An exception is described in [1]. Maybe you have to change the numeric preferences, according to the file you want to import, in Edit -> Preferences menu before trying to drag and drop a file. Another alternative is to import your file using File -> Import ASCII... (or simply type Ctrl + k). You have to adjust...

Unable to import opju Origin files

Just a comment, Python is working fine in SciDAVis 1.26 - built from source; environment: Slackware-current (64 bits), Python 3.8.2, GCC 9.3.0, Qt 5.13.2, PyQt 5.13.2

[2.0.10 - beta] Can't use Python as scripting language
-
Hi, Well.. The curve associated to the table should be updated automatically when data points are changed. You can change the fit function using right click on the fitted curve -> Edit Function. But I'm not sure if this is what you want to do... Regards
-
Hi jl, If possible, attach an .opju file here (or send it to my email: fellypaoøyahoo·com·br - change ø by @ and · by .), so we can send it to the liborigin developers to be used as an example to improve the import tool. Best regards. Fellype
-
Hi, the file opens, meaning I briefly see the graphs and data sheets but they disappear at once... The same happens here. Any clues ? Click on View menu -> Project explorer (or just type Ctrl + e) --> You data should be in the Project explorer sub window, under the folder "Folder1" About opju files.. I never needed to open this kind of file. But I guess it's supported. Try to open it changing the file type to "All files" in the open project dialog window. Best regards, Fellype
-
Hi, Is there a way to prevent this from happening? The only way to prevent it happening in SciDAVis is to remove from your table the points that have the same X value The options box for integration is also different from anything I can find online... Where are you searching this? The latest version of the handbook can be found at: https://highperformancecoder.github.io/scidavis-handbook/ Best regards.
-
You need only to adjust the column types according to your needs. Select the desired column and change the appropriated type on the right side of the table.
-
We could put -lc in the qmake file for building the plugins, but what purpose does it actually serve? This question was already made before... and it was already answered (in somewhere in SF...). The fit plugins are intended to supply some non-linear fit (NLF) functions that are difficult to be implemented using the NLF provided by SciDAVis (but it is not limited to be used only for NLF functions) - an exception is the planck_wavelength plugin, that was included in order to provide a better convergence...
-
Hi Miquel, Very good tip. I have been using python to manipulate data for so long that I can't remember muParser's functions even looking at the manual :-þ
-
Hi Richard, SciDAVIs does not have formulas to manipulate an entire column at once like in Origin. The available commands/formulas to manipulate data (supposing you are using SciDAVIs on Windows) can be found at https://highperformancecoder.github.io/scidavis-handbook/scripting.html If you want to normalize a column (to set its maximum value equals to 1), you can just right-click on the desired column and click on "Normalize columns". You can also select multiple columns and perform the same ope...

Here the file size with 100k rows and 10 cols is ~74MB.

Hi, Double precision is the only option available in SciDAVis. An alternative to reduce the file size is to save your project as a compressed file (.sciprj.gz)
-
Hi Grzegorz, Since you have the data in a file, I guess it is better to import the file instead of do copy-paste. - Go to File -> Import ASCII... (or type Ctrl + k) - In the import dialog: 1° - uncheck the following checkboxes: Numeric data; simplify white spaces 2° - change the separator from "SPACE" to ";" 3° - select the desired file and click open Your file will be imported to a new table, with date in the 1st column and the numbers in the other. Now, you need only to adjust the column types...
-
Miquel, Using the last patch all import options in the importASCII dialog work fine - new table, new columns/rows and overwrite existing table. Good job and thank you for the effort in solve the issue.
-
I believe the problem originally reported is solved ... But we ended up finding others. I'll be out for 10 days, but I can examine the other bugs and create reports after that.
-
I assume that you use Qt4-python2. Yes, this is my config. Sorry for my previous report... I tried to import an ascii file using the importASCII python command.. In that case the cells are filled with ' - ' instead of zeros for the numbers with comas. Running new tests using the import ASCII dialog: Importing to a new table works as expected if the appropriated decimal separator (' , ') is chosen. But not if decimal separators remain the default (' . ') - the zeros appear in the cells in this case....

Hi Miquel. The patch does not work for me.

Hi Miquel, Yes, the patch solves the problem. Good job.

To change colors or delete the existing config file for SciDAVis solves the problem on Linux. I've tested only the 1st option on windows and it works.
-
The config file ~/.scidavisrc certainly does not exist on Linux installations. I'm not sure if it exists on windows, and don't know about Mac. On Linux,the configuration file for SciDAVis is 'SciDAVis.conf', whose path is usually: ~/.config/SciDAVis/SciDAVis.conf For some unknown reason, the file SciDAVis.conf is not being generated (or found) on windows 10 - the version used by Claudia Dörr when reporting the issue. This is supposed to be generated in the first run, but, even on Linux, it is generated...

Hello Claudius, There are no such feature in SciDAVis. But if you are using it on Linux with python scripting enabled, I can tell you the directions to automate your fits. Best regards

Russell, The steps to reproduce the crash after load the project file are: - click on the data range selector button; - click on a point of the curve "T_2" It is always reproducible here. Regards

Crash using data range selector in graphs with linear fit

Number of major ticks of log axes not preserved on re-scale
-
Hi Tobias! There is a bug here. Not in SciDAVis, but in GSL (the routine used to perform the fit). See: https://sourceforge.net/p/scidavis/scidavis-bugs/277/#6ca8 There are two possible workarounds for you: 1- Remove the first line of your table (the line which contains zeros), and try to fit using the y=ax function (works here); 2- Instead of zero, in the first cell of column 3 (the yerr column), put there a very small value, say 1e-50, and perform a linear fit with the function y=ax+b (works here,...

It is possible to build SciDAVis 1.25 using Qt5, but, as Russell pointed out, this requires qwt5 and qwtplot3d built against Qt5 too. See: https://github.com/highperformancecoder/scidavis/pull/96 https://github.com/highperformancecoder/scidavis/pull/97 Some people reported that this is working (fine?)! Most distributions (probably all them) will not add to their repositories a qwt5 version patched to build against Qt5 (the qwt5_qt5 package mentioned by Russell). Then a complete move from Qt4 to Qt5...
-
No, it isn't. I guess that a new version will be reseased soon, but there is no exact date for this.
-
I guess this is a bug that is probably related to SFBug #359 (https://sourceforge.net/p/scidavis/scidavis-bugs/359/). The bug was already fixed at upstream.

[1.23.4 - beta] Duplicated 2d graph window have different layer height
-
Hi. SciDAVis does not have this feature at the moment. I guess the best you can do is to add a text on another layer and rearrange the layers according to your needs: - Go to graph menu -> Add text; - Choose "On New Layer"; - click on the graph and type the desired title (set the frame as "none" too); - resize and rearrange the layers. You should got a result like that in the attached figure. Best regards.

I could not reproduce the crash using a Linux (Slackware) package or a Windows one (via WINE). The SciDAVis version used was 1.23.1 in both cases. And the project file I've used is attached ¹ Maybe an issue that affect only Mac installations. ¹ @David, Your project file was not attached...

It is not blank here, only unorganized (probably due to my default settings).
-
Hi Jan, What version and operating system are you using? Have you tried to change the fitting algorithm from the default one - Scaled Levenberg-Marquardt - to another like the Unscaled LM or Nelder-Mead simplex in order to see if this produce the same error? By the way, you must have your reasons for trying to fit a linear function using simply y=ax. But the function y=ax+b must provide the same result for the value of 'a', within the uncertainty interval, of course.
-
This is reproducible here (Slackware 14.2, SciDAVis 1.23.4). Only adding the steps to reproduce: - from a table, plot a graph; - double-click on a curve; - click on "Plot Associations..." → the "Plot details" window closes and nothing else happens

Line color is preserved, but gets overwritten by a rectangular frame, as you can check by exporting to SVG and editing the obtained file. I thought this could be the problem after try to export a graph using SciDAVis on Windows, but it was to late to tell you this. Attached patch solves the problem. Yes, it solves the problem. Thank you!

Hi Phil, This is a bug. See: https://sourceforge.net/p/scidavis/scidavis-bugs/178/ https://sourceforge.net/p/scidavis/scidavis-bugs/270/ The best option at the moment is to select only the X1, Y1, yEr1, X2 and Y2 columns to plot and to add the yEr2 error bars to Y2 using the Graph menu -> Add Error Bars... (or type Ctrl + B) You can see more on the SciDAVis manual at https://highperformancecoder.github.io/scidavis-handbook/sec-graph-menu.html Best regards.

Fixed here. Thank you!

[1.23.2 - beta] Falsely changed project after window lose focus
-
Yes, the patch fix the problem. In Fedora I have no problem to change theme/style through Edit/Preferences/Style menu. I mean that the style used does not have effect on display or not the right-menu icons, since Oxygen style is not available when one ran SciDAVis using XFCE DE.
-
In addition: The theme/style used in SciDAVis (Edit -> Preferences... -> Style) does not seem to have any effect - tested with Oxygen and GTK+ using KDE and with GTK+ on XFCE.
