i hope you add generate the median curve of all selected curves

I am a little unsure if you just want a dialog where you can evaluate the sum of the point series or if you want to plot a function?

In your example all the point series are strait lines. Is that always the case? I.e. do the point series always contain only two points?

i want to plot afunction

all cases of point sieres i explain it in the following image

Thanks for the explanation.

I have attached a plugin PointSum.py, which should do what you want. You need to place the file in the Plugins folder where Graph is installed. You also need to install Python 3.2 from https://www.python.org/ftp/python/3.2.5 … -3.2.5.msi

Now you should see a menu item called *Plugins|Sum of point series*. It will create a function that adds all point series together.

Please let me know if this works as you expected.

this is the screen

thank you sir thank you very very very very much

yes it work exactly what i want

only three notes

it select all funtions automatic if you can make me choose this will be beter if not no problem

it plot afunction but icant get the points if you can make me get it,s points as atable this will be beter if not no problem

the x range is the common range not full x range please please make it full x rang

I have attached an updated version of the plugin. It will now allow you to select the point series you want to add. It will also add the full range and create a point series instead of a function.

excellent 100%

thank you very very very much

yo do all of every thing exactly

thank you thankyou thank you

new update has losted point of y

it seems the problem in the end

in this type of sieres

Unfortunately I am not able to reproduce the problem. Could you please attach the grf file you use so I can reproduce it?

this the graph files

Thanks. I can reproduce the problem now. It turns out it is a rounding problem, so the plugin was calculating the y-coordinate a little to the right of the point and therefore missed the value of the point.

I have attached a fixed version of the plugin.

still the problem

Can you still reproduce the problem with the two grf files you attached?

Are you sure you use the plugin I attached in the last message and not a previous version?

yes of course i do it and problem is still

i hope you do to help me know what is the problem

if the problem solved with you but still with me i will remove program and reinstall it again

sorry sir i find what problem it is very strange

if i rename the last update as the name of the first release exact the problem finish

now i can say the last update working 100%

thank you very very much

I am glad it works for you now.

I am a little unsure what you did, but I just noticed that the file doesn't work if the file name contains spaces or non-english characters. I will need to fix that.

when i download it the browser give it automatic the same name of the first release but add new mumber 1 . 2.3 and so on

this number was the problem

when you take it copy paste in plugins folder it dosent work but the previous update working instead of the final update but i didnot note that till you wonder from me
