Axios not loading data to vue - vue.js

Question

I am trying to load cytoscape graph using vue and axios. Anyway cant configure cytoscape so I tried first with axios and vue only. There is still problem with scope, but I can't figure where? What should I change? How to properly set vue and axios.
EDIT
So after setting this.nodes i would like to draw a grapg in cytoscape.js , but I always get errors:
-The style property text-outline-color: is invalid
-Do not assign mappings to elements without corresponding data (e.g. ele 6b899f09-359e-424d-9461-d71c8c3fcd3b for property text-outline-color with data field faveColor); try a [faveColor] selector to limit scope to elements with faveColor defined
-Uncaught TypeError: Cannot set property 'mapping' of null
I believe it is array problem, but I can't figure out how to set array properly so this can work.
Here is code:
draw: function(){
this.cy = cytoscape({
container: document.getElementById('cy'),
layout: {
name: this.main_layout,
padding: 10
},
style: cytoscape.stylesheet()
.selector('node')
.css({
'shape': 'data(faveShape)',
'width': 'mapData(weight, 40, 80, 20, 60)',
'content': 'data(name)',
'text-valign': 'center',
'text-outline-width': 2,
'text-outline-color': 'data(faveColor)',
'background-color': 'data(faveColor)',
'color': '#fff'
})
.selector(':selected')
.css({
'border-width': 3,
'border-color': '#333'
})
.selector('edge')
.css({
'curve-style': 'bezier',
'opacity': 0.666,
'width': 'mapData(strength, 70, 100, 2, 6)',
'target-arrow-shape': 'triangle',
'source-arrow-shape': 'circle',
'line-color': 'data(faveColor)',
'source-arrow-color': 'data(faveColor)',
'target-arrow-color': 'data(faveColor)'
})
.selector('edge.questionable')
.css({
'line-style': 'dotted',
'target-arrow-shape': 'diamond'
})
.selector('.faded')
.css({
'opacity': 0.25,
'text-opacity': 0
}),
elements: {
nodes: this.nodes
},
ready: function(){
window.cy = this;
}
});

I assume that response.data is an array or object ans vm.projekt with null there is no vue-getter registred. So please try to do
Vue.set(vm, 'projekt', response.data) there is also a $set in every vue instance (this)
instead of
vm.projekt = response.data
In general i would advise you to push ajax-datas into reactive arrays, that works very well.
