Which chart package are you using? Is it Google Chart, Chartjs, D3, etc? Tks,

Pls try this code:

BarChart::create(array(
    ...
    "options" => array(
        ...
        "vAxis" => array(
            "viewWindowMode" => "explicit",
            "viewWindow" => array(
                "max" => $yourMaxValue,
                "min" => $yourMinValue,
            )
        )        
    )

Let us know if it works for you or not (if not pls post error messages and screenshots). Tks,
