help to fit graph report into dashboard / screen

help to fit graph report into dashboard / screen

Hey guys maybe somebody can help me

1. Can I change the graph report size to be seeing in the window without using a scroll bar?

2. I am embedding reports like the previous in my dashboard, however the graph, even with a scroll bar, won't show the whole X axis, below the code I am using in it, I'm using a previous dashboard code so maybe I need an extra line to fit it in, thanks 

      .monthFrame{
                width: 99%;
min-height:380px;
max-height:100%;
                //margin-left:10px;
                //margin-right:10px;
                margin-top:12px;
                border: 1px solid #efefef;
//box-shadow: 1px 1px 2px #d1d1d1;

                -webkit-border-radius: 25px;
                -moz-border-radius: 25px;

.zc-component .monthFrame
{
border:none;


                                <iframe class='monthFrame' frameborder='0' scrolling='yes' src='<%=zoho.appuri%>report-embed/Comparativo_mensual/zc_Header=false&zc_BdrClr=transparent'></iframe>
<!---div class="monthFrame" elName='zc-component' viewLinkName='Comparativo_mensual' params='zc_Header=true'></div---> 

Thanks,
