Template with several other elements

[OpenFoam-User]

Hello,
is it possible to use a template that has other elements like text, arrows? Something like this:

When I try that template:

import figurefirst as fifi
import matplotlib.pyplot as plt
import numpy as np

layout = fifi.FigureLayout('template.svg')
layout.make_mplfigures()

x = np.linspace(0, 2*np.pi, 200)
y1 = np.sin(x)
y2 = np.cos(x)
y3 = np.sinc(x)

axes = layout.axes

axes['mainaxis'].plot(x, y1)
axes['secondaxis'].plot(x, y2)
axes['thirddaxis'].plot(x, y3)

layout.insert_figures()
layout.write_svg('out.svg')

I get the following error:

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    layout = fifi.FigureLayout('template.svg')
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 732, in __init__
    figuretree,grouptree,leafs,svgitemtree = self.make_group_tree()
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 867, in make_group_tree
    traverse_svgitems(self.layout,svgitemtree)
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 860, in traverse_svgitems
    traverse_svgitems(child,tree_loc)
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 860, in traverse_svgitems
    traverse_svgitems(child,tree_loc)
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 856, in traverse_svgitems
    item = FFSVGItem(child)
  File "/home/significantcell2/.local/lib/python3.8/site-packages/figurefirst/svg_to_axes.py", line 256, in __init__
    x = float(self.node.getAttribute('x'))
ValueError: could not convert string to float: ''

I 've attached template.svg here:
template.zip

Something is wrong with svgitem tag in your svg. As I understand, you have a group of objects (texts and an arrow) tagged as a svgitem, and that group does not have an x attribute, which causes the error. I tried removing svgitem tag from your svg file and then the code runs.

I guess if you want to tag a group, you need to use the svggroup tag, or tag individual objects as svgitems. There is an example about svgitems: https://github.com/FlyRanch/figurefirst/tree/master/examples/svgitems

In case you just want these elements to be present in the output, you can put them into a different layer and then you don't need any tags (see template_layer2.svg).
template_layer2.zip

Hope this helps.

@kukasyachka : Thank you very much.

@kukasyachka : Is it ok to ask questions here?
Is it possible to change text using figureFirst module, I mean I have to create a text placeholder in the template then add the text from the Python code.

Thanks

Yes you can change text, but the documentation on that functionality is somewhat sparse. There are some basic examples in the directory Anna pointed out, specifically, this notebook and associated template file: https://github.com/FlyRanch/figurefirst/blob/master/examples/svgitems/svgitem_editing_example.ipynb
