Update a specific field on a tophosts widget

[CristianR]

Hello Community,

How I can update the threshold field on the tophosts widget? I tried like below but that will update the field columnsthresholds.threshold.14.1 but also will remove all the other fields.

{
    "jsonrpc": "2.0",
    "method": "dashboard.update",
    "params": {
        "dashboardid": 162,
        "pages": [
            {
                "dashboard_pageid": 1327
            },
            {
                "dashboard_pageid": 1334,
                "widgets": [
                    {
                        "widgetid" : 3535,
                        "type": "tophosts",
                        "fields" : [
                               {
                                "type": 1,
                                "name": "columnsthresholds.threshold.14.1",
                                "value": "9700"
                                }
                        ]
                    }
                ]
            }
        ]
    },
    "auth" : "{{auth}}",
    "id": 2
}​

Any help is appreciated.

Thank you.
