If you edit the source of the dashboard you should be able to find a section called "layout" within the JSON, as below. Adjust the "w" value for each of your visualization to 1/3 of the "width" value (in my case 1440/3 = 480). Set the second viz "x" position to 480 and the third viz "x" position to 2x480 (960) and this should give you an even 1/3 split. It doesnt look like there is an easier way (ie it "snapping" to 1/3 grid size) unfortunately. "layout": {
"type": "grid",
"options": {
"width": 1440,
"height": 960,
"display": "auto"
},
"structure": [
{
"item": "viz_NFlIOSoJ",
"type": "block",
"position": {
"x": 0,
"y": 0,
"w": 480,
"h": 250
}
},
{
"item": "viz_ZN3u7AG0",
"type": "block",
"position": {
"x": 480,
"y": 0,
"w": 480,
"h": 250
}
},
{
"item": "viz_6G8sJ2GL",
"type": "block",
"position": {
"x": 960,
"y": 0,
"w": 480,
"h": 250
}
}
],
"globalInputs": [
"input_global_trp"
]
}, I hope this helps!
