Save data and Y axis

[pescadoranton]

Hi!
I am using instrumentino for a university project and it works well, but I would like to save data from arduino on a csv file.
I am trying to modify instrumentino but I am starting with python and it dosen't work, someone could help me?

On the other hand, is it possible to change the axis units of the graph? I would like use absolute values, not %.

Thanks!

Hi, Instrumentino by default already saves all of your acquired data in csv files. Look for the "log" folder. It should be filled with csv files and text files, where your acquired data and operations are saved. I think this is mentioned in the Instrumentino articles, which you can find in the documents folder <https://github.com/yoelk/instrumentino/tree/master/documents> Regarding your second question, I've made the Y axis to show percentages so multiple signals may be shown on a single axis system (rather than having multiple Y-axes, which would take up a lot of screen space and might lead to confusion). But if you only have one signal, and you'd like to change the Y-axis units, here's how to do it (I think): - Open the file log_graph.py - on line 65 you should find the setting of the Y-axis range: self.axes.set_ybound(0,100) So replace 0 and 100 to your own range - On line 182 you'll find the method that translates real values to values to be shown on the graph: def NormalizePositiveValue(self, value, yRange): # unipolar range [X, Y] or [-X, -Y] relevantEdge = yRange[0] if yRange[0] >= 0 else yRange[1] return abs(value - relevantEdge) / abs(yRange[1] - yRange[0]) * 100 So Instead of the calculation in this method, you'd want to simply do: def NormalizePositiveValue(self, value, yRange): return value I believe this should do the trick. Good luck! Joel
