Vistasmakes shapes with loop in Plotly
So far i got this code `
shapes: [
{
type: "line",
xref: "x",
yref: "paper",
x0: data[i],
y0: 0,
x1: data[i],
y1: 1,
line: {
color: "red",
width: 2,
dash: "longdash",
},
},
],
I want to set up a vertical line in my plot on a specific position and this works fine. Now how can i do more of the exact same line ? cause my array of data will be updated after a button. If there is only one point in my array i get a line , but if a try to set up a second line it just wont work. Can i somehow make a for loop to plot me those lines ? i just want to plot more than one vertical lane at different places.

You can construct shapes as an array containing multiple dictionaries: something in the form [{shape 1 info}, ..., {shape N info}]. To do that you can loop through your data array, and use data[i] as the x-coordinates of each line in your shapes array.
Here is some sample code and the codepen.
var data = [1,2,3,5]
shapes = []
for (let i = 0; i < data.length; i++) {
shapes.push({
type: "line",
xref: "x",
yref: "paper",
x0: data[i],
y0: 0,
x1: data[i],
y1: 1,
line: {
color: "red",
width: 2,
dash: "longdash",
},
})
}
var trace1 = {
x: [2, 6],
y: [1, 2],
mode: 'markers+lines'
};
var layout = {
title: 'Vertical Line Annotations',
xaxis: {
range: [0, 7]
},
yaxis: {
range: [0, 6]
},
shapes: shapes
};
var plotdata = [trace1];
Plotly.newPlot('myDiv', plotdata, layout);
